Anonymous users2024-02-12Dear, hello liquid stool, happy to answer for you, <>
The calculation of the production date and shelf life is as follows1Expiration time = shelf life days + production date time, how many days are left to expire = expiration time - present moment. For example, if a cookie with a shelf life of 6 months and a production date of January 1, 2020, and the expiration time = January 1, 2020 + 6 months, the expiration date is July 1, 2020.
2.Assuming that the "present moment" is June 27, 2020, how many days are left to expire = July 1, 2020 - June 27, 2020, which is 3 days, and there are 3 days left to expire (excluding June 27, 2020). Shelf life usually refers to the period of time during which a prepackaged food maintains its quality under the storage conditions specified on the label.
During this period, the product is fully merchantable and maintains the unique qualities that do not have to be stated in the label. In general, the shelf life of food involves not only the single dimension of time, but also the storage environment of the food, and the shelf life of the food should be analyzed in the specific storage state.
