    Modelling textural changes of vegetables during acidification under isothermal and non-isothermal conditions2001In: Acta Horticulturae, ISSN 0567-7572, Vol. 566, p. 323-328Article in journal (Refereed)
    Abstract [en]

    Acidification can be used to improve the quality of canned vegetables because it can decrease thermal processing requirements. Moreover, there is some evidence that acidified vegetables retain a better texture than non-acidified ones. Optimisation of the acidification processes requires the knowledge of the relationship between texture and thermal process at low/moderate temperature. The main objective of this work was the modelling of textural changes of vegetables during acidification under isothermal conditions, and the application of the model to predict textural changes in non-isothermal processes. Turnip was the vegetable used in the experiments. The effect of pre-treatments (blanching, freezing/thawing, calcium addition and vacuum infusion of water before acidification) on the kinetics of textural changes during acidification was also studied. Turnips were acidified in acetic acid under isothermal (20, 50, 70, 80, 90 and 100°C) and non-isothermal conditions (20 to 90°C). Texture was modelled by a two subtract first order kinetic model, assuming an Arrhenius-type dependence of the rate constants on temperature. The model parameters were estimated by nonlinear regression. At temperatures lower then 70°C no significant changes in texture were detected. At higher temperatures the model showed a good fit to the data for all the conditions tested. Acidification decreased the percentage of heat labile substrate from 96% to 62%, thus improving firmness retention. The parameters of the kinetic model estimated under isothermal conditions provided an adequate prediction of texture changes under non-isothermal conditions. The methodology developed in this work can be further applied to model the textural changes of vegetables during other thermal processes, such as drying, blanching, and frying.

    Improvement of texture by modifying processing conditions2003In: Acta Horticulturae, ISSN 0567-7572, Vol. 604, p. 277-283Article in journal (Refereed)
    Abstract [en]

    Fruit and vegetable processors, faced with the challenge of gaining and maintaining a healthy position in the competitive fruit and vegetable sector, are optimising traditional processes towards product quality. Using frozen potatoes as a case study, the aim of this study was to evaluate the potential of improving the texture of potatoes by modifying the processing conditions. The texture of processed frozen potatoes is the result of the integral effect of the unit operations applied through the production chain. Production of frozen potatoes includes a blanching, a freezing, thawing/cooking step before being served. In this study, blanching temperatures from 70 to 97 °C up to 10 minutes were tested and combined with freezing by two freezing methods, impingement and air-blast freezing. The texture was measured after cooking of frozen potatoes in boiling water. Besides texture, water holding capacity, microstructural evaluation and pectinmethylesterase (PME) activity were determined. Blanching of potatoes prior to freezing can both improve water holding capacity and texture of potatoes, but this effect depends on the freezing rate and blanching temperature. Potatoes frozen with fastest freezing method are firmer and hold more water than the ones frozen by air-blast freezing. Blanching at 70 °C can lead to potatoes that after cooking retain a firmer texture, compared with blanching at 90 °C. The duration of the blanching treatment has also an important effect on texture changes. The studies of PME activity showed a good correlation between texture and PME for blanching at 90 °C, but for blanching at 70°C and longer times, the development of texture does not seem to be solely related to PME activity. Microstructural studies showed that the differences in texture are due to differences in the degree of starch gelatinisation and integrity of the cellular structure.

    Assessment of Self-Heating in Wood Pellets by FE Modelling2017Conference paper (Refereed)
    Abstract [en]

    The self-heating process in a laboratory scale experiment has been modelled using the Comsol Multiphysics software. In the simulations the gas flow and air movement in the volume and heat diffusion in the bulk were taken into account however only one reaction in the pellets bulk is considered. The input data is found from measurements of the reaction chemistry and the heat transfer properties. It is found that all relevant physics is needed in order to obtain reasonable predictions in particular the heat transfer between the bulk and the gas is important but also condensation and evaporation of moisture.

    An evaluation of residential sprinklers and water mist nozzles in a residential area fire scenario2017Report (Other academic)
    Abstract [en]

    Commercial residential sprinklers are usually fitted with 3 mm glass bulbs having a nominal operating temperature of 68°C or a high-sensitivity solder link, usually with a nominal temperature rating of 74°C. Previous work show that there is a significant potential for improving sprinkler response times in a residential room fire scenario by using glass bulbs with a lower Response Time Index (RTI) and lower operating temperature than commonly used. The objective of this study was to investigate any improved performance due to earlier activation of residential sprinklers. A series of fire tests was conducted inside a test compartment sized 3.66 m by 3.66 m. The fire test source consisted of either a simulated or authentic upholstered chair. For the majority of the tests, the flow rate of the residential sprinkler was 30.3 liter/min (corresponding to the minimum design density 2.05 mm/min as per the recommendations in NFPA 13D and 13R). Additional tests were conducted at 60.6 liter/min (the minimum design density 4.1 mm/min as per NFPA 13). Tests were also conducted with commercial low- and high-pressure water mist nozzles and a stand-alone high-pressure water mist system.

    The results show that earlier activation of residential sprinklers had a small effect on its performance, especially for the authentic upholstered chair scenario, when flowing 30.3 liter/min. The rather small effect is probably due to that the discharge density was too low to provide fire suppression. When the flow rate was increased to 60.6 liter/min, the performance was considerably improved as compared to the flow of 30.3 liter/min. Any improvement in performance of earlier activation was, however, not investigated for the 60.6 liter/min flow rate.

    The flow rates of the commercial low- and high-pressure water mist water mist nozzles ranged from 17.2 liter/min to 36.7 liter/min. Roughly, it could be concluded that the performance of the water mist nozzles were comparable or better than the residential sprinkler at approximately half the water flow rate for the tested fire scenarios.

    The stand-alone high-pressure water mist system had a flow rate of 8.2 liter/min. The performance was comparable to that of the other water mist nozzles in the study The performance was comparable to that of the other water mist nozzles in the study, despite a considerably earlier activation. However, the results indicate that the performance was relatively much influenced whether the simulated upholstered chair was orientated with its front towards the test compartment or with its front towards the back wall (poorer performance). This would suggest that the position of the fire test relative to the position of the unit is a crucial factor and underlines the importance of a thoughtful positioning in practical applications.

    Response Times Of Sprinkler Glass Bulbs In A Residential Room Fire2017In: International Fire Protection, no 71Article in journal (Other (popular science, discussion, etc.))
    Abstract [en]

    The response time of fire sprinklers is essential for their performance, especially in applications where life safety protection is desired. The earlier the sprinkler activates, the smaller the size of the fire. The aim of this study was to determine the response time – and the corresponding heat release rate – of different sprinkler glass bulbs in a residential room fire scenario.

    Water distribution tests using Extended Coverage sprinklers for the Muskö Tunnel2017Report (Other academic)
    Abstract [en]

    The objective of the tests was to determine the water distribution characteristics using different water pressures and sprinkler spacing of two selected Extended Coverage sprinklers. The sprinklers may be used for the protection of the Muskö tunnel and the test set‑up simulated a freight truck trailer positioned inside the tunnel.

    Adequate sprinkler coverage would require that sprinklers are positioned close to the peak of the ceiling. A relatively short vertical distance from the sprinklers and the ceiling is also essential for proper thermal activation. These requirements are best met by the use of upright sprinklers. Two extended coverage upright sprinklers with a K‑factor of 363 (metric) and 202 was selected for the tests.

    For the extended coverage upright K363 sprinkler (Tyco model EC‑25), a sprinkler spacing of 4.0 m is recommended, in order to account for the fact that full coverage of the freight truck trailer was not achieved at the tested 4.2 m spacing. A density of 10 mm/min requires an operating pressure of around 0.7 bar at this particular spacing.

    The tested extended coverage upright K202 sprinkler (Tyco model EC‑14) provided a wider water discharge pattern, with a proper water distribution on the top of a freight truck trailer positioned offset in the tunnel at sprinkler spacing up to 5.0 m. For an actual installation, a K202 sprinkler designed for a density of 10 mm/min require an operating pressure of around 3.6 bar at this particular spacing.

    Boundary crossing in product introductions considering humans, technology and organization2014In: Proceedings of ODAM NES 2014 / [ed] O. Broberg, N. Fallentin, P. Hasle, P.L. Jensen, A. Kabel, M.E. Larsen, T. Weller, 2014, p. 349-354Conference paper (Refereed)
    Abstract [en]

    The objective of the paper is to analyze how a product introduction involving Swedish-Chinese collaboration was influenced by human, technological and organizational aspects. The study showed that technical challenges concerned the infrastructure for communication and quality issues; organizational challenges concerned the new project model and updating drawing versions; and human related challenges included cultural differences and communication. The product introduction was highly challenging by crossing earlier boundaries in the human, technical, and organizational subsystems. Strong work demands were placed on the individuals while offering great opportunities for individual learning. Concurrent development of a new project model resulted in organizational learning.

    Comparison between GaAs and graphene QHR standards for resistance realisation at SP2016Conference paper (Refereed)
    Abstract [en]

    We report the first precision QHR measurements at SP using a graphene chip. We compare the results of a resistance calibration using GaAs based chips with the results using a graphene chip. The results agree within a few parts in 109 for calibrations of 100 Ω and 10 kΩ resistors. Consistency checks indicate that the uncertainty is lower with the graphene chip, and the noise level is slightly lower. The measurements with the graphene chip were performed exclusively at 4.2 K, which simplifies the calibration procedure considerably compared with GaAs chips.

    Bacteriological safety issues in red meat and ready-to-eat meat products, as well as control measures2002In: Meat Science, ISSN 0309-1740, E-ISSN 1873-4138, Vol. 62, no 3, p. 381-390Article in journal (Refereed)
    Abstract [en]

    The importance of Eschericha coli O157, Listeria monocytogenes and Salmonella typhimurium DT104 as meat-borne pathogens is well established. Pathogenic bacteria such as Aeromonas spp., Arcobacter spp., psychrotrophic Bacillus cereus, Campylobacter spp., Clostridium botulinum and non-invasive Listeria monocytogenes can be regarded as rookies, but not yet firmly associated with today's production of red meat and meat products. The development of PCR and other DNA-based techniques will shed new light on so called emerging pathogens. Important safety issues in meat production, such as insufficient cleaning and disinfection (including the stable/lairage, processing environment), carcass decontamination and chilling, and cross contamination are discussed. Furthermore, probability modelling of survival and growth is identified as an important way to achieve a better understanding of how to deal with the complexity of further processing, including heat treatment and storage. © 2002 Elsevier Science Ltd.

    Utveckling av Robust Produktionsutrustning: En guide för god samverkan mellan beställare och leverantör2016Book (Other academic)
    Abstract [sv]

    Av dagens globala och allt hårdare konkurrens följer korta marknadsfönster och krav på snabb volym- uppgång i produktion. Det innebär i sin tur ökade krav på snabb och effektiv utveckling av produktions- utrustning som säkerställer hög prestanda direkt vid produktionsstart. Robust produktionsutrustning med hög produktionseffektivitet och minskade kostnader för drift och underhåll är därför en av de viktigaste faktorerna för stark konkurrenskraft och hög lönsamhet för svenska industriföretag. God samverkan mellan beställare och leverantör är nyckeln till framgång i denna typ av investerings- projekt. Denna handbok presenterar därför en modell som kan användas av tillverkande företag som vill utveckla robust produktionsutrustning. Modellen och övriga rekommendationer i handboken fokuserar på projekt som ska genomföras i stark samverkan och riktar sig till både beställaren och leverantören. Den har utvecklats i forskningsprojektet ”EQUIP – kund- och leverantörsintegration i utformning av produktionsutrustning” som finansierats av KK-stiftelsen under 2013-2016. Modellen består av sju utvecklingsfaser som är baser- ade på produktionsutrustnings livscykel: Fas 1 – Förstudie Fas 2 – Konceptstudie Fas 3 – Upphandling Fas 4 – Detaljerad utformning Fas 5 – Uppbyggnad Fas 6 – Installation och driftsättning Fas 7 – Produktion I varje fas presenteras kritiska aktivitetssteg och rekommendationer för hur ansvaret för dessa bör fördelas inom och emellan deltagande parter. Modellen använder ett livscykelperspektiv för utvecklingsprojekt för att underlätta samverkan samt tydligare visualisera sambandet mellan aktiviteter och deras påverkan på projektets framgång. Inom ramen för ett investeringsprojekt finns stor potential att utveckla hållbara produktionslösningar. Därför presenterar denna handbok även sju guider som kan stödja er i att ta fram produktionsutrustning som är säker, lean och hållbar under hela utrustningens livscykel. Huvudsyftet med handboken är att underlätta samverkan under hela investeringsprojektet på ett sätt som gagnar båda parter och bidrar till varaktiga relationer. Forskningsprojektets resultat visar att det finns ett stort intresse för främjad samverkan från både beställ- are och leverantör. Därför behövs stöd, verktyg och beredskap från båda parter för att våga investera tid och resurser på samverkan redan från början, i de tidiga faserna av ett nytt utvecklingsprojekt. Det är då potentialen att lägga grunden till långsiktig samverkan och utforma bästa möjliga produktionsutrustning på kortast möjliga tid är som störst.

    The principles of high voltage electric field and its application in food processing: A review2016In: Food Research International, ISSN 0963-9969, E-ISSN 1873-7145Article in journal (Refereed)
    Abstract [en]

    Food processing is a major part of the modern global industry and it will certainly be an important sector of the industry in the future. Several processes for different purposes are involved in food processing aiming at the development of new products by combining and/or transforming raw materials, to the extension of food shelf-life, recovery, exploitation and further use of valuable compounds and many others. During the last century several new food processes have arisen and most of the traditional ones have evolved. The future food factory will require innovative approaches food processing which can combine increased sustainability, efficiency and quality. Herein, the objective of this review is to explore the multiple applications of high voltage electric field (HVEF) and its potentials within the food industry. These applications include processes such as drying, refrigeration, freezing, thawing, extending food shelf- life, and extraction of biocompounds. In addition, the principles, mechanism of action and influence of specific parameters have been discussed comprehensively. © 2016.

    Design-driven innovation: A literature review2016In: Exploring design-driven innovation: A study on value creation by SMEs in the Swedish wood products industry, p. 246-282Article in journal (Refereed)
    Abstract [en]

    Design-driven innovation focuses on innovating product meanings. This concept has been studied since the early 2000s from a variety of perspectives, and in different contexts. This paper presents a review of published research. The aim of this review is to provide a comprehensive understanding on the contribution of design-driven innovation to value creation. In a systematic literature review, 57 papers and book chapters on this subject were identified and analyzed. The facets of design-driven innovation which contribute to value creation were identified through an iterative coding process. The value of design-driven innovation is created by including a focus on the intangible values of products. Five facets of design-driven innovation which contribute to value creation have been identified: (1) understanding new product meanings; (2) required knowledge; (3) actors and collaborations; (4) capabilities; and, (5) process. These facets, and the connections between them, are presented in a theoretical framework. This paper contributes to theory by presenting the theoretical framework that provides an overview of available knowledge and that creates a context for future research. The main practical implication is that the five facets are connected and reinforce each other. Therefore, companies need to approach design-driven innovation from a holistic perspective.

    European Initiative on CDIO in Raw Material Programmes2017Conference paper (Other academic)
    Abstract [en]

    One of five Knowledge and Innovation Communities (KICs), was launched in Europe in 2014 and has its focus on exploration, extraction, mineral processing, metallurgy, recycling and material substitution of raw materials. To reach the vision, where the European Union’s industrial strength is based on a cost-efficient, secure, sustainable supply and use of raw materials, a new generation of skilled people entering industry, universities and research needs to be developed. Today’s technical MSc graduates in raw materials and especially primary resources (i.e. exploration, extraction, mining and mineral processing and metallurgy) best suits large companies where they often act as specialists and experts. For small to medium enterprises as well as for our future engineers other skills than technical are necessary. As a part of the KIC Raw Materials, the education project “The implementation of CDIO in raw material programmes” started in 2016. The project focuses, during 2016-2017, on (WP1) faculty- and (WP2) pilot case development. There are no academic institutes in Europe that have yet applied CDIO for primary resource related MSc programmes. This paper describes an education project within the KIC Raw material and presents key outputs with implementing CDIO in mining and metallurgy related programmes.

    Effect of hydrocolloids and emulsifiers on the shelf-life of composite cassava-maize-wheat bread after storage2016In: Food Science & Nutrition, E-ISSN 2048-7177, Vol. 4, no 4, p. 636-644Article in journal (Refereed)
    Abstract [en]

    The objective of this study was to evaluate the effect of hydrocolloids and/or emulsifiers on the shelf-life of composite cassava-maize-wheat (ratio 40:10:50) reference bread during storage. Added hydrocolloids were carboxymethylcellulose (CMC) and high methoxyl pectin (HM pectin) at a 3% level (w/w) and/or the emulsifiers diacetyl tartaric acid esters of monoglycerides (DATEM), lecithin (LC), and monoglycerides (MG) at a 0.3% level (w/w). After 4 days of storage, composite breads with MG had comparatively lower crumb moisture while crumb density was similar in all breads. The reference bread crumb firmness was 33.4 N, which was reduced with an addition of DATEM (23.0 N), MG (29.8 N), CMC (24.6 N) or HM pectin (22.4 N). However, the CMC/DATEM, CMC/LC, and HM pectin/DATEM combinations further reduced crumb firmness to <20.0 N. The melting peak temperature was increased from 52 C to between 53.0 C and 57.0 C with added hydrocolloids and/or emulsifiers. The melting enthalpy of the retrograded amylopectin was lower in composite bread with hydrocolloids and emulsifiers, 6.7–11.0 J/g compared to 20.0 J/g for the reference bread. These results show that emulsifiers in combination with hydrocolloids can improve the quality and extend the shelf-life of composite cassava-maize-wheat breads. © 2015 The Authors.

    Creatinga structured MEETing arena for knowledge-sharing2014Conference paper (Other academic)
    Abstract [en]

    This paper aims to describe how to create and structure a meeting arena bycombining organisation structure and information structure; this will be used in orderto create an innovative and creative arena for knowledge sharing and problemsolving within the company. The model is exemplified by four industrial casestudies.Results reveal that most of the companies do not have any standards forinformation- or knowledge sharing, most improvement potentials are seen instructuring and storing the right information (IS), aiming from tacit towards explicitknowledge (OS) and this could be done by structuring the questions in the OS-M-ISmodel and by creating innovative and creative meeting arenas.

    Synchronized smoldering combustion2018In: Europhysics letters, ISSN 0295-5075, E-ISSN 1286-4854, Vol. 121, no 5, p. 50002-p1-50002-p2Article in journal (Refereed)
    Abstract [en]

    Synchronized, pulsating temperatures are observed experimentally in smoldering fires.The entire sample volume (1.8 l) participates in the pulsations (pulse period 2–4 h). The synchronylasts up to 25 h and is followed by a spontaneous transition to either disordered combustion orself-extinguishment. The synchronization is obtained when the fuel bed is cooled to the brink ofextinguishment. Calculations for adiabatic conditions, including heat generation from combustion(nonlinear in temperature) and heat storage in sample (linear in temperature), predict divergingsample temperature. Experimentally, heat losses to surroundings (linear in temperature) preventtemperatures to increase without bounds and lead to pulsations.

    Food supply in a network context: An alternative framing and managerial consequences in efforts to prevent food waste2016In: British Food Journal, ISSN 0007-070X, E-ISSN 1758-4108, Vol. 118, no 6, p. 1407-1421Article in journal (Refereed)
    Abstract [en]

    Purpose– The purpose of this paper is to present a “network” framing of food supply arrangements. Such frameworks have been asked for in previous research as supplements to prevailing supply chain conceptualizations.Design/methodology/approach– The framework builds on industrial network theory. According to this approach, business reality is analyzed in three inter-related dimensions: the activities undertaken, the resources used for this undertaking, and the actors controlling resources and activities. For each dimension, relevant concepts are derived for analysis of the features of food supply and food waste.Findings– The network framing was useful for analyzing the prerequisites and consequences for two approaches to reduce food waste: one based on extension of shelf-life, the other relying on enhanced responsiveness in the supply arrangement. The framework was then used for suggesting managerial actions to reduce food waste through increasing activity coordination, resource combining, and actor interaction with consideration of potential consequences of such actions.Practical implications– Managerial issues in food supply are discussed with regard to the role of activity coordination, the role of resource combining, and the role of actor interaction in efforts to prevent food waste.Originality/value– The paper suggests a novel approach for analyzing food supply networks with particular focus on food waste reduction. Such framings are applied in other supply systems, and requested by food supply researchers.

    Tjänstefiering i tillverkande företag2016Report (Other academic)
    Abstract [sv]

    Hårdare konkurrens, alltmer omfattande miljökrav och allt snabbare teknisk utveckling innebär stora utmaningar och driver företag att söka nya sätt att göra affärer och skapa värde för befintliga och nya kunder. Nya konsumentbeteenden som t ex delningsekonomi (sharing economy) och teknologisk utveckling inom exempelvis digitalisering, additiv tillverkning och förnyelsebar energiproduktion skapar också möjligheter till nya affärer och ökad hållbarhet. Med dessa scenarier på väg att förverkligas kommer det inte att räcka för kommersiella aktörer att bli bättre. De måste ha ett mer radikalt förhållningssätt till sin verksamhet och fråga sig vad som är teoretiskt möjligt när det gäller kostnadseffektivitet och resurssnålhet. Ett naturligt steg är att fokusera på att addera olika former av tjänster till sina varor, som till exempel reservdelar, underhåll och servicekontrakt. Varorna blir plattformar för tjänster som skapar nytta och ökat kundvärde – kallas ofta för tjänstefiering. Det kan också innebära att man förflyttar sig närmare slutkunden i värdekedjan. Men framför allt krävs det att man anammar ett nytt sätt att tänka, en tjänstelogik. Värdelogik/tjänstelogik är ett synsätt där man tar utgångspunkt från värdet kunden försöker skapa för sin kund. Där värde i användning är det centrala till skillnad från varulogik där transaktion av varor i sig är det centrala. Att tjänstefiera ett varufokuserat/tillverkande företag, innebär både möjligheter och utmaningar som bör identifieras, bedömas och hanteras. Att ha tydliga mål och en strategi för sin tjänstefiering är centralt. Övergång från försäljning av varor till försäljning av värde är ett stort steg eftersom det innebär en förändring i verksamheter som rör företagets kärn-verksamhet. Varor som är företagets inkomstkällor blir plötsligt kostnadsposter om kunderna betalar för levererat värde istället för varorna. Detta får radikala konsekvenser för organisation och produktutveckling. Utmaningarna till trots har övergången till värdeförsäljning dock visat sig fungera mycket väl vid ett flertal tillfällen och stora effektiviseringsvinster kan göras när det lyckas. Idag ses tjänstefiering mer som en kontinuerlig process för att skapa en portfölj med erbjudanden med den balans mellan varor, tjänster och affärsmodeller, som på bästa sätt stödjer kundernas värdeskapande processer. Varufokus överges för kundvärdefokus.

    Unveiling Fundamental Relationships in Industrial Product Development2016In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 50, p. 204-209Article in journal (Refereed)
    Abstract [en]

    Identification and clarification of relationships between product properties is fundamentally important in industrial product development. The process is however frequently perceived difficult. The presented research aims at clarifying if a visual tool can provide help in this work. The tool is a combination of previously known techniques and has so far been implemented at two product developing companies. Results and reactions from the tests are hitherto positive and the conclusion is therefore that this extended casual diagram can be a useful addition to the product developer’s toolbox.

    Towards a methodology for Kaikaku realization2011In: Proceedings of the 4th International Swedish Production Symposium, SPS11, / [ed] Jan-Eric Ståhl, 2011Conference paper (Refereed)
    Abstract [en]

    In today's globally competitive market where the speed of change is increasing it is of great importance that manufacturing companies are striving to achieve improvements in their production systems resulting in competitive edge. One way of doing this is to strive for radical change by becoming more innovative. Today however, there's a lack of modern methods guiding companies to be not only innovative and creative in their production development process, but also increasingly more innovative while using it. Hence, the objective of this paper is to present and discuss a preliminary first draft of a Kaikaku realization method, primarily based upon Concept Modelling and research within the domains of Operations Management and Strategy, Innovation theory and Change theory. The result is a sequential work process that provides guidance from an initial “current state” of production to a more desirable “future state” based upon an aggressive target that is set in line with the production strategy. Finally, future research is discussed, implying that more research should be subjected to the actual work process as well as the main support provided in the process - aggressive target setting and facilitation of innovative thinking.

    The role of pH in microstructural assembly2017Conference paper (Refereed)
    Abstract [en]

    Proteins are important biopolymers that can contribute significantly to food structure. Controlling the manner in which they aggregate and form matrices within food systems is fundamental to sensory attributes and can have an impact on digestive properties. This work investigated the structuring behaviour whey protein isolate (WPI) over the entire acidic pH range from pH 1.0-6.8. WPI is a commercially available mixture of several proteins. β-lactoglobulin is most abundant and tends to dominate the functionality. Some important aspects are the clarity of protein solutions in beverages, the temperature of denaturation, the aggregation characteristics and consequently the gel forming properties. pH is a key factor which affects all of these properties and there remains aspects worthy of further investigation. In this presentation, the role of pH in denaturation, aggregation and structuring will be discussed in detail along with the trends observed. Some previously unknown aspects surrounding the behaviour of whey proteins at specific pH points and their applicability to commercial products will be highlighted

    Modifying the microstructure and mechanical properties of whey protein isolate gels using large deformation oscillatory strain2016In: Food Hydrocolloids, ISSN 0268-005X, E-ISSN 1873-7137, Vol. 61, p. 672-677Article in journal (Refereed)
    Abstract [en]

    The effect of oscillatory shear during heat-induced gelation of whey protein isolate has been investigated. For each gel sample, a single oscillating strain was applied during the gelation process from within the range of 0-1.0. A strain sweep was then used to evaluate the linear viscoelastic region as well as the fracturing properties of each gel. The application of strains lower than ∼0.01 during gelation did not affect the storage modulus while larger strains resulted in lower storage moduli in the linear viscoelastic region. Furthermore, gels produced under small (<0.01) strain amplitudes showed a single fracture point, while gels produced under high (>0.01) amplitude strain were characterised by a two-step fracture pattern. Between the fracture steps, strain hardening behaviour was observed. Confocal laser scanning microscopy was used to identify structural differences between the gels. Greater inhomogeneity was found in gels produced under large amplitude compared to small amplitude strain. It is suggested that localised redistribution of aggregates due to shear during gelation increases the average pore size and possibly creates two distinct types of aggregate structure with differing moduli. The combined effect of heating rate and oscillatory strain was also investigated. We postulate that the mechanism underlying our observations is generic to many gel systems.

    Evaluation of drying methods on the content of some bio-actives (lycopene, β-carotene and ascorbic acid) of tomato slices2016In: African Journal of Food Science, ISSN 1996-0794, E-ISSN 1996-0794, Vol. 10, no 12, p. 359-367Article in journal (Refereed)
    Abstract [en]

    Tomato (Solanum lycopersycum L.) is one of the most important vegetables worldwide. As it is a relatively short duration crop and gives a high yield, it is economically attractive. Thus, the objective of this study was to evaluate the effect of drying method on the quality of the dried tomatoes based on three parameters viz; lycopene, ß-carotene and ascorbic acid contents. Thirty-six kilograms of tomatoes were sorted, cleaned, blanched and divided into three equal portions of 12 kg each. The tomatoes were sliced into 4, 6 and 8 mm, then sun, solar and hybrid dried, respectively. The value of lycopene content obtained for sun dried tomatoes ranged from 23.89 to 18.77 mg/100 g, solar dried ranged from 24.51 to 22.56 mg/100 g and hybrid dried ranged from 25.12 to 24.65 mg/100 g. The average value of β-carotene content obtained for sun dried tomatoes ranged from 4.12 to 3.72 mg/100 g, solar dried ranged from 4.94 to 4.25 mg/100 g and hybrid dried ranged from 4.98 to 4.65 mg/100 g. The values of ascorbic acid obtained for sun dried tomatoes ranged from 17.04 to 5.60 mg/100 g, solar dried ranged from 23.73 to 13.37 mg/100 g and hybrid dried ranged from 29.20 to 24.82 mg/100 g. Hybrid dried tomatoes slice showed higher retention of lycopene, ß-Carotene and ascorbic acid than both the solar and open sun dried methods.

    Influence of packaging material and storage temperature on the texture, colour, and weight of broccoli2003In: Acta Horticulturae, ISSN 0567-7572, Vol. 600, p. 323-326Article in journal (Refereed)
    Abstract [en]

    Sophisticated packaging solutions can be used in order to preserve vegetables during storage and transport. Polymeric films with selective barriers matching the respiration of the produce, thereby creating an ideal atmosphere inside the package, are available on the market. Fresh broccoli (Brassica oleracea L. var. italica 'Monterey') heads were packed in 4 different commercially available polymeric films, and stored at 4 and 10°C respectively. During storage the weight, colour, chlorophyll content and texture were monitored. The investigated polymer materials were oriented polypropylene (OPP), polyvinyl chloride (PVC) and two types of polyethylene (PE) packagings. The choice of packaging material had an impact on the measured quality parameters of broccoli. Storage in OPP resulted in the longest storage life. Broccoli stored in PVC film deteriorated faster than broccoli packaged in the other materials. It was also observed that the influence of the type of packaging material was more important at the higher temperature. The implications of this work for the packaging and storage of fresh broccoli will be discussed.

    The effect of packaging material on the sensory properties of broccoli2003In: Acta Horticulturae, ISSN 0567-7572, Vol. 599, p. 91-95Article in journal (Refereed)
    Abstract [en]

    Three different commercially available polymeric films were studied to determine their effect on the sensory properties of fresh broccoli (Brassica oleracea L. var. Italica cv. 'Marathon'). The polymer materials investigated were oriented polypropylene (OPP), polyvinyl chloride (PVC) and one low density polyethylene (LDPE) which contained an ethylene absorber. The fresh broccoli was packaged and stored for one week at 10°C or 3 days at 4°C followed by 4 days at 10°C. The oxygen and carbon dioxide concentrations inside the packages were monitored during storage. After storage the broccoli was evaluated according to sensory analyses, i.e. triangle test and quantitative descriptive analysis, by an analytical panel. The panel judged the broccoli according to smell, taste, texture and appearance. The triangle test showed significant differences between the smell of the broccoli samples, stored in the different packaging materials, when cooked. However, no differences between the raw broccoli, stored in the different packaging materials could be detected. The quantitative descriptive analysis showed that the following attributes; fresh smell and taste, chewing resistance, and crispness, differed significantly between the packaged broccoli when cooked. The appearance was shown to be the sensory property of broccoli most affected by the storage conditions, i.e. packaging material used and storage temperature. The results indicated the importance of the packaging material for maintaining the broccoli quality. However, one packaging material that was able to maintain all the studied sensory properties could not be identified. Copyright © ISHS 2003.

    An Overview on Magnetic Field and Electric Field interactions with Ice crystalization; Application in case of frozen food2017In: Crystals, Vol. 7, no 10, article id 299Article, review/survey (Refereed)
    Abstract [en]

    Ice nucleation is a stochastic process and it is very difficult to be controlled. Freezing technologies and more specifically crystallisation assisted by magnetic, electric and electromagnetic fields have the capability to interact with nucleation. Static magnetic field (SMF) may affect matter crystallisation; however, this is still under debate in the literature. Static electric field (SEF) has a significant effect on crystallisation; this has been evidenced experimentally and confirmed by the theory. Oscillating magnetic field induces an oscillating electric field and is also expected to interact with water crystallisation. Oscillating electromagnetic fields interact with water, perturb and even disrupt hydrogen bonds, which in turn are thought to increase the degree of supercooling and to generate numerous fine ice crystals. Based on the literature, it seems that the frequency has an influence on the above-mentioned phenomena. This review article summarizes the fundamentals of freezing under magnetic, electric and electromagnetic fields, as well as their applicability and potentials within the food industry.

    Ekodesign: praktisk vägledning2011Book (Other academic)
    Abstract [sv]

    Det blir alltmer uppenbart att vi behöver vara rädda om vår jord. Miljöfrågorna startade med debatten om kvicksilver och DDT och handlade sedan om direkta utsläpp från fabriker. Idag inser vi vikten av att sätta produkten i centrum. Att förbättra produktens egenskaper under hela livscykeln är centralt för ett framgångsrikt miljöarbete. Produktutvecklare är en av de grupper som har störst möjlighet att påverka denna utveckling i en positiv riktning. Många lösningar ger – förutom bättre miljö – dessutom ökat kundvärde till lägre kostnader. Bra miljö genom ekodesign är ett nytt sätt att tänka. Denna bok ger vägledning i hur man kan integrera miljöaspekter i produktutvecklingen. Boken visar också ett antal verktyg, checklistor och exempel på ekodesign i företag. Boken vänder sig i första hand till produktutvecklare och konstruktörer men också till företagsledning, inköpsavdelning, marknadsförare och miljöansvariga. Dessutom lämpar sig boken väl för undervisning inom ekodesign.
