Shelf life is not used to judge whether food has gone bad.
1. The shelf life of the product refers to the best edible period of the product provided by the manufacturer, which is generally marked on the product with limited use time. 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.
2. The storage condition of food is very important to the quality of food. The shelf life is usually determined according to the suitable storage conditions of this kind of food. For example, on the packaging of ordinary biscuits, we can see the words "storage method: store in a cool and dry place, and eat as soon as possible after opening".
That is to say, if cookies are stored in an environment with severe sunlight, high temperature or high humidity, their actual shelf life will be much shorter than the preset shelf life on the package. The integrity of food packaging is also an important standard to measure food quality.
3. 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.
