The storage conditions of food are very important to the quality of food. The shelf life is usually determined according to the relevant suitable storage conditions of this kind of food. During the warranty period, the manufacturer of the product is responsible for the quality of the product that meets the relevant standards or explicitly guaranteed quality conditions. However, the shelf life is not the only criterion to identify whether the food has gone bad, and the food may go bad prematurely due to storage methods, environment and other problems.
Food with defective packaging is easy to get wet or breed bacteria, and its safety is relatively low. For opened food, its shelf life will also be shortened. Therefore, food should be eaten as soon as possible after opening to avoid mildew.
