Drinks and food are sealed. Such as no obvious change in appearance, fading, turbidity, precipitation, etc. After the shelf life, you can still drink it, but pay attention to the taste, and don't drink it if it smells bad. In addition, it is recommended to drink it within 1 day after opening the bottle.

Shelf life is not the only criterion to determine whether food has gone bad. The shelf life of food consists of two elements, one is storage condition and the other is duration, which are closely related and inseparable. Food labels must indicate the storage conditions, which usually include normal temperature, dark storage, cold storage and frozen storage.

If the storage conditions of products do not meet the requirements, the shelf life of food is likely to be shortened. Even the food within the shelf life may deteriorate prematurely due to changes in storage methods, environment and other factors; And the food beyond the shelf life does not mean that it must have gone bad and can't be eaten. Specifically, you can judge for yourself.
