Abstract [en]

Agar-based extracts from Gelidium sesquipedale were obtained by applying a conventional hot water treatment and alternative ultrasound- and microwave-assisted methods, with and without the application of an alkaline pre-treatment. The alkaline pre-treatment produced refined extracts with higher purity; however, extraction yields increased from 2–5% to 7–19% by omitting this step. In particular, the ultrasound-assisted extraction allowed reducing 4-fold the extraction time, while keeping constant or even increasing the yield (up to 19% for the 1 h extraction) with respect to the conventional protocol. Interestingly, the presence of proteins and polyphenols conferred the semi-refined extracts a relatively high antioxidant capacity (19–24 μmol TE/g extract). The refined extract produced by the standard protocol formed the strongest hydrogels (>1000 g/cm2). On the other hand, the semi-refined extracts produced by the alternative protocols formed slightly stronger hydrogels (337–438 g/cm2) than the refined counterparts (224–311 g/cm2), due to their greater molecular weights of the former ones. LCA assessment showed lower global warming potential for the semi-refined extracts, especially the ultrasound-assisted extraction, hence highlighting the potential of this method to produce more sustainable agar-based extracts for food-related applications.

Abstract [sv]

Sammanfattning:Det här dokumentet har tagits fram i ett utvecklingsprojekt tillsammans med Mashie Foodtech Solutions (tidigare DKAB) och RISE och förutom den här rapporten så har projektet även innefattat framtagande av beräkningsmetodik samt implementering i Hantera.

Syftet med projektet är att hjälpa organisationer, främst kommuner och regioner, att ta att ta ett bredare grepp kring hållbarhetsfrågor och relaterade frågeställningar. Mer specifikt syftar projektet till att hjälpa till med att ta fram målsättningar och att nå målen med ett holistiskt angreppsätt, där samtliga frågeställningar beaktas och där uppfyllandet av ett eller några mål inte sker på bekostnad av andra målsättningar.

De frågeställningar eller områden som har inkluderats i det här projektet är klimatavtryck från livsmedelsinköp, andel ekologiska livsmedel av totala inköp, andel svenska livsmedel av de totala inköpen och matsvinn.

Dessa områden beskrivs i rapporten och det ges nationella riktlinjer för vart och ett av områdena. Även nuläget för respektive område presenteras, d.v.s. var de som använder Hantera befinner sig just nu. Eventuella målavvägningar mellan områden, d.v.s. om det föreligger konflikter gås igenom. Det ges också råd om hur arbetet kan bedrivas för att kunna nå målen.

Implementeringen av projektets resultat i Hantera har resulterat i en ny modul, där projektets områden visualiseras på ett innovativt och användarvänligt sätt. En av de nya funktionerna möjliggör jämförelser emellan organisationer!

Abstract [sv]

En växande insikt om betydelsen av livsmedel för global miljöpåverkan, särskilt animaliska livsmedel inklusive sjömat, har lett till ett behov hos producenter såväl som handeln att kommunicera miljöpåverkan av råvaror och produkter genom livsmedelskedjan. Detta visar sig i form av nya krav på att dokumentera produkters miljöavtryck, t ex vid certifiering och i regelverk. EU initiativet inom hållbar utveckling med en "inre marknad för gröna produkter" är ett exempel, med målet att dokumentera miljöavtrycket av produkter på EU marknaden enligt metoden Product Environmental Footprinting (PEF). Målet är att göra det möjligt för konsumenter, handel, producenter och lagstiftare att göra medvetna val och att etablera drivkrafter mot reducerad miljöpåverkan i produkters värdekedja.

För att kunna leva upp till dessa nya krav, krävs tillgång på representativ data av hög kvalitet, något som i stort sett har saknats för sjömatsprodukter. För att göra högkvalitativa, representativa data kring resursåtgång och miljöpåverkan av sjömatsprodukter (inklusive biomassa som direkt eller indirekt används till foder) tillgängliga, initierade den norska sjömatsbranschen ett pilotprojekt. Projektet definierade en rekommenderad metod och struktur för datainsamling och använde denna metod för att samla in tillgängliga data för ett antal pilotfall. Metoden för datainsamling presenteras i detta dokument och kan, tillsammans med pilotdataseten som gjorts tillgängliga i projektet, användas av näringen som grund för en bredare datainsamling för att skapa en utbyggd sjömats-LCI-databas.

Abstract [en]

An increasing awareness about the important role of food, in particular animal-based foods including seafood, for global environmental impacts has led to a need of producers as well as retailers to communicate environmental impacts of raw materials and products through the food chain. This is demonstrated by new requirements to document the environmental footprints of products, e.g. by certification schemes and policies. The EU policy for sustainable development with its "single market for green products" is one example, aiming for documenting the environmental footprint of products on the EU market according to the Product Environmental Footprint (PEF) method. The goal is to enable consumers, retailers, producer, regulators and policy makers to make conscious choices and establish drivers for reducing environmental impacts throughout product supply chains.

To be able to live up to these new requirements, representative data of high quality is needed, something which has largely been missing for seafood products. To make high-quality, representative data on the resource use and environmental impacts caused by seafood products (including biomass used directly or indirectly for feed) available, the Norwegian seafood industry initiated a pilot project. The project defined a recommended method and structure for data collection and used this method to collect available data for a number of pilot cases. The method for data collection is presented in this document and can, together with the pilot data sets made available through the project, be used by the industry as a basis for a broader data collection to create an expanded seafood LCI database.

Abstract [en]

The Life Cycle Assessment methodology often applies a product perspective but can be used to assess novel production technologies by comparing novel products with a baseline product, as long as the functional unit of the product is considered to be the same. There is increasing environmental concerns in society and pressures on industry to take into account their impact on the environment. Tools are available for this, but not tools adapted to specific industry needs. The reasons to use LCA are foremost to guide the development towards the most sustainable solutions and to evaluate the market potential from an environmental perspective. Challenges arise when applying LCA in early development stages, e.g. getting access to recent development data, to increase commitment and incentives to take early LCA results into consideration, to present results in an attractive way etc. LCA calculations must also keep up with the sometimes rapid development. In order to meet these challenges interactive report software have been introduced to industrial partners (non-LCA experts) in an EU project called FutureFood (Grant agreement no: 635759). The project goal is to develop a new processing technology for foods (CO2 drying). In order to meet the LCA related challenges a platform has been used that is developed by PRé Consultants (Pre, 2016?), called Share and Collect. It allows LCA experts to develop tools for non-experts so that users are able to alter parameters in the LCA model and assess the result of the changes. It is done by providing the industrial partners with an intuitive web based graphical user interface (GUI). When a user changes input data in the GUI, parameter values also change in the model, an LCA calculation engine runs the model and the GUI presents the corresponding results. In the project a tool for assessing the processing technology has been developed and the industrial partners  are provided rights to access the tools and create ‘what if’ scenarios. Examples of changes are change of electricity production, transport distances, transport types or modes, raw material source, packaging, production resource or energy efficiency etc. The tool has been evaluated by the non-LCA expert industrial partners, and the first review results show that it is user friendly, visually appealing and interesting in its interactive way because of the instant feedback of results. Tailored models such as the ones developed in the project have the potential to support knowledge based decisions in innovation projects in companies.
