Extended data:

The shelf life of a product refers to the best edible period of the product. The shelf life of the product is provided by the manufacturer and marked on the product for limited use. During the warranty period, the manufacturer of products is responsible for the quality of products meeting relevant standards or explicitly guaranteed quality conditions, and the seller can sell these products with confidence, and the consumer can use them with confidence.

Shelf life is not the only criterion to identify whether food and other products have deteriorated. The reason for deterioration may be the premature deterioration of substances with changes in storage methods and environment. Therefore, food should be eaten as soon as possible before the expiration of the shelf life.

The shelf life of opened food will be shortened, so use it as soon as possible to avoid the deterioration of product quality.
