Project background (background info can be found in Taten Statt Worte)
Optimising cold chains of fruits and vegetables across all unit operations is of key importance to maintain fresh food quality and to reduce food losses. Temperature and the gas composition in the air are affecting decay and food quality, so need to be controlled during precooling, refrigerated transport and cold storage. By optimizing these environmental parameters, shelf life can be maximised, and the need for protective packaging is reduced. Currently extensive monitoring is performed of the environmental conditions in food supply chains (air temperature and humidity). The key objective is to use these monitored data to improve commercial cold chains and, in the end, to reduce the plastic packaging wherever possible. This project is performed in collaboration with the Swiss retailer Coop.
