Abstract [en]
Swallowing disorders affect approximately 8% of the global population. It is more prevalent in the elderly, leading to malnutrition and dehydration. Different strategies have been investigated to design new texture-modified food products that would reduce or mitigate the suffering from these swallowing disorders. Despite the recent interest and research in this area, there are, however, still a lot of unknowns regarding the specific sensory insights by this targeted group. The aim of this work was to understand if the ease of swallow and related sensory characteristics are perceived differently by “young” and “elderly” healthy individuals. Broccoli purees with different textural properties were created by changing the fluid component (water or xanthan solution) or processing conditions. Samples were evaluated by an elderly panel (n = 19, average age = 68.9 years) and a young panel (n = 16, average age = 25.4 years). Multivariate data analysis strategies were used to understand the intrapanel sample discrimination and to compare between panels. Results showed a similar overall discrimination between samples between young and elderly panels. The use of xanthan improved the ease of swallow in both age groups. In the absence of xanthan gum, processing conditions determined the ease of swallow, which was related to the particle size distribution. Nevertheless, small differences were found between panels. For example, the elderly panel was more sensitive when discriminating samples based on the ease of swallow (p =.005). Therefore, panelist age seems to be relevant when designing tailored foods enhancing the ease of swallow for the elderly populations. Practical Applications: The present study highlights new insights on the relevance of age and sensory capabilities when designing new texture-modified food products. It also provides new insights regarding the key sensory attributes to consider and how these are affected by the type of food processing. © 2022 The Authors.
