Try not to eat cream and cheese that have expired for 3-5 months. Although you may not see anything on the surface, the shelf life of food is scientifically based.

The reason why food has a shelf life is that the additives and preservatives in it will fail, the residual chemicals will be easily oxidized, microorganisms will easily breed, unpredictable changes will easily occur, and it will easily cause great harm to consumers.

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.
