Abstract

Compared to other food categories, fruits and vegetables are the most wasted. This leads to the squandering of economic, social, and environmental resources. The reallocation of fruit and vegetable waste (FVW) into animal feed contributes to the sustainability of livestock production, reducing the impact of feed production for land use. In this study, the fruit and vegetable waste from the General Wholesale Market of Milan was considered. FVW samples were collected for one year and were analysed for safety parameters and nutritional, vitamin, and mineral composition. Data showed that dry matter (DM) was on average 10.82 ± 1.21% and neutral detergent fibre (NDF) was on average 22.43 ± 4.52% DM. The presence of soluble sugars (30.51 ± 7.61% DM, on average) was also detected. However, the high moisture content of this waste makes it easily perishable, with detrimental effects on quality, storage, and transportation. A strategy was therefore proposed to reduce the water content of FVW by pressing. Overall, the results highlighted the significant nutritional value of FVW from the wholesale market and the need to develop appropriate technologies to maintain the food chain line safe.
