Shelf life and quality of raw materials depend on optimal conditions for long-term storage. The optimal storage time, is the longest period, at which the loss of quality and nutritional value of raw materials do not exceed the allowable limit, depends on the temperature and humidity conditions. Throughout the entire storage period, the constant temperature should be maintained as long as possible, since its fluctuations even within +5°C can seriously affect the storage duration. On the territory of the Russian Federation, the temperature of outdoor air changes during the day from about 5 to 15°C, reaching 30°C in some regions. The seasonal temperature also varies significantly. Optimal conditions for storing pectin-containing raw materials are temperature limits of 0 − 5°C. One of the modes of storage of raw materials is storage in a refrigerated state, when the temperature of the raw materials and the surrounding space is lowered to − 10°C. Such conditions can be achieved by equipping storage facilities with artificial cooling. Using thermophysical methods, it is possible to objectively assess the optimal storage conditions for raw materials and predict storage periods.
