The shelf life of dark chocolate is generally about one year, but if it is stored for too long, its air oxidation will increase, which will cause the air oxidation degree of dark chocolate vegetable oil to exceed the standard, but it is generally difficult to distinguish it from the surface, and only machinery and equipment can detect it. Taking food with excessive malondialdehyde will have a great impact on our human body, such as gastrointestinal discomfort, diarrhea and liver damage. In addition, if it is stored for a long time, frost will appear on the surface, which will also make the taste of chocolate worse. So it is not recommended to eat unopened and unopened chocolate at the same time.
This is my answer to the question whether dark chocolate can be eaten after its expiration date. When we eat chocolate, we'd better buy it now and eat it now. When buying, we should not only pay attention to the production date, but also try to shorten the storage time. It is best to seal it in a fresh-keeping bag and store it in the refrigerator to avoid frosting affecting the taste.
