How to calculate the shelf life?

Food, medicine and some daily necessities all have a shelf life. When people go shopping, they often pay extra attention to whether the goods they buy are expired or about to expire. So when people see the production date and the shelf life marked on the goods, I believe they will still have a question, that is, how to calculate the shelf life? Let me tell you how to calculate the shelf life. How to calculate the shelf life? (1) The shelf life of food is more complicated. There are two ways to calculate the shelf life. One is to calculate the shelf life from the time of production, such as bread and other finished foods. The other is to calculate the shelf life from the time of opening, such as salt, which is a food that can be stored for a long time.
