FRUITS AND VEGETABLES SHELF LIFE AND QUALITY PREDICTION METHOD

摘要

A fruits and vegetables shelf life and quality prediction method. In the invention, starting from the time a fruit or vegetable is picked, a temperature recording instrument is used to continuously record the ambient temperature of the location of the fruit or vegetable throughout the entire supply chain period, including during harvesting, sorting, storage, transport, and time on shelf. The effective accumulated temperature of a botanical fruit during the entire supply chain period is calculated, and said temperature is used to predict the commodity rate and the nutritional quality of the fruit. Commodity rate, hardness, and vitamin C content have an inverse correlation with accumulated temperature. Thus, the accumulated temperature during the storage and shelf life of harvested fruits and vegetables may be used to predict the commodity rate and nutritional quality thereof. This has important theoretical significance and good practical value for providing guidance for production practices that keep fruits and vegetables fresh during storage and transport, and that reduce post-harvesting damage to the fruits and vegetables.
