Shelf life usually refers to the period during which prepackaged foods can maintain its quality under the storage conditions specified in the label. During this period, the products are completely suitable for sale, and the unique qualities that need not be stated or have been stated in the label are maintained. The shelf life of general food involves not only the single dimension of time, but also the storage environment of food, so the shelf life of food should be analyzed in the specific storage state.

Article 99 of China's Food Safety Law, which was passed and implemented in 2009, clearly stipulates that the shelf life mentioned in this law refers to the time limit for prepackaged foods to maintain its quality under the storage conditions specified in the label. On May 20 1 1 year 13, the Ministry of Health issued GB 7718-201"prepackaged foods Labeling Standard", which redefined the shelf life. In the new standard, the shelf life is defined as: prepackaged foods's storage indicated on the label.

During this period, the products are completely suitable for sale, and the unique qualities that need not be stated or have been stated in the label are maintained. In order to ensure the quality and safety of food and the health of consumers, it is necessary to set a reasonable time limit for the storage and circulation of food. Through the shelf life of food, consumers can know the quality of the products they buy, and manufacturers can specify the correct distribution channels and sales models.

The shelf life of food is an important content of food label, which is an important information element to effectively ensure food quality and an indispensable contract certificate between food producers, operators and consumers. More importantly, it is also an important legal basis for supervision institutions at all levels in law enforcement.
