Food storage is a way of decreasing the variability of the food supply in the face of natural, inevitable variability. It allows food to be eaten for some time (typically weeks to months) after harvest rather than solely immediately. It is both a traditional domestic skill (mainly as root cellaring) and, in the form of food logistics, an important industrial and commercial activity. Food preservation, storage, and transport, including timely delivery to consumers, are important to food security, especially for the majority of people throughout the world who rely on others to produce their food.
Significant losses of food are caused by inadequate storage conditions as well as decisions made at earlier stages of the supply chain, which predispose products to a shorter shelf life. Adequate cold storage, in particular, can be crucial to prevent quantitative and qualitative food losses.Food is stored by almost every human society and by many animals. Storing of food has several main purposes:
Storage of harvested and processed plant and animal food products for distribution to consumers
Enabling a better balanced diet throughout the year
Reducing food waste by preserving unused or uneaten food for later use
Preserving pantry food, such as spices or dry ingredients like rice and flour, for eventual use in cooking
