There is no magic date. It will depend on the quality of the food to begin with, the quality and type of container and the subsequent handling and storage thereof. Even canned, food will degrade and change color, texture and flavor. I have used some items that were a year past the coded date. They were edible, but I could tell the difference when compared to newer product. Many canned foods are coded with 2 and even 3 year shelf lives. But for best quality and nutrition, plan to use canned goods within a year. If you are trying to maintain a cache of canned foods, use product throughout the year and replace it with fresh stock. Use the FIFO method - First In First Out. Always use the oldest items first.

Most canned foods don't have an exact expiration date. Unless they were improperly canned, they are not degrading in the same way uncanned food does - but they will deteriorate in nutrition and quality. If the can has a best-by date on it, try to use it before then. If not, try to use it within a year of purchase. If home-canned, try to use it before the next harvest. As always, check canned goods for signs of spoilage before using them.
maybe shortly after the expiration date
It depends what kind of expiration date like on milk or food or drinks it should say A black Print that says a month and a date and the year thats the expiration date...
As a general rule, it is not recommended to consume any food product past its expiration date, even if it is unopened. The expiration date is determined based on the manufacturer's testing of the product's quality and safety up to that date. Consuming expired food products can pose a risk to your health due to potential bacterial growth or degradation of the product's quality.
