When consumers buy food at supermarkets, it is easier for consumers to ignore the issue of food shelf life. Which foods are easier for us to ignore?

1. Frozen foods are often not stored at the refrigerating temperature marked on the packaging. If so, they will expire prematurely, such as cooked food. At the same time, refrigerated meat cooked foods, soy products, salad dishes, etc. may also be replaced by the label, obviously it was done the first day, but it is attached to the day's label. If consumers do not raise their vigilance, they feel that they are still eating directly without heating, and that the total number of pathogenic bacteria or bacteria exceeds the standard, even leading to the risk of bacterial food poisoning.

2, frozen foods are written --18 degrees below the shelf life for many months, in fact, it has no way to achieve complete stability in the transport and supermarkets at -18 degrees. The freezer is open, directly in contact with the air at room temperature, and many people are turning, so they will expire in advance without any suspense, and the taste of the flavor changes, it will no longer be worth so much money. Therefore, when buying these frozen foods, do not buy them at the critical period, or buy those products that are most recently manufactured.

3. If a food cannot be stored under the specified conditions, the shelf life is not counted. For example, yoghurt should be refrigerated, and if sold at room temperature, its true shelf life will be greatly reduced.

4. Some foods are long-shelf foods, such as sweets, honey, solid drinks with high sugar content, etc. They are virtually safe for several years, because they are too dry and microbes cannot breed.
