If the shelf life has not passed, it can certainly be used for other purposes. Steaming steamed bread and making soup are good choices. Products that reach the shelf life immediately are also called "temporary products". The temporary value of different types of milk is also different. For example, UHT pure milk, the shelf life is generally about half a year, so its temporary value is 2 days before expiration; For foods with a shelf life of less than 15 days like pasteurized milk, the critical period is 1-4 days before expiration.

in principle, as long as it is within the shelf life, you can safely eat it. However, due to the influence of people's consumption habits, the price of temporary products is often much lower than that of newly produced products, and many people will take the opportunity to pick up the leaks.
