Abstract
Reducing food waste throughout the agri-food chain, as well as sustainable food choices by consumers, can contribute to more efficient resource management. In addition, food insecurity (FI), a socio-economic inability to obtain appropriate quality food in sufficient amounts, still exists. To provide scientific data related to FI, i.e., by reducing food waste, the aim of this pioneering study was to evaluate selected food quality components of food at the end of the date of minimum durability and during the following 6 months of storage. Food safety and sensory attractiveness of the products were taken into consideration. Food safety measurements included microbiological quality, water activity and pH analysis. Sensory attractiveness was evaluated by the quantitative descriptive analysis (QDA) and instrumental analysis. The evaluated foodstuffs were characterised by good sensory quality and safety on the last day of minimum durability. This condition was maintained for up to 3 months of storage. However, after 6 months, significant sensory changes were found, which disqualified the products. The obtained results provide the basis for establishing guidelines that will facilitate the organisation of traders and food banks as well as consumers to make a decision not to throw food but eat or transfer it for social purposes.Keywords
