If the can is directly refrigerated after opening, it may increase the risk of bacterial contamination and metal dissolution. Experts suggest that it should be stored in glass, ceramic or plastic containers and consumed within 2 to 3 days, which is safer.
How to store canned food after opening?Many people buy canned food. How do you eat canned food? Some people eat directly after opening the can, while others pour the food out of the bowl and then eat it. But if you can’t finish the can after opening, how should you best store it?
Before the food is finished, most of it is wrapped directly in plastic wrap or placed in a crisper, and then stored in the refrigerator. If you are used to eating directly from the canned container and the canned food is not finished, many people may also put the canned food directly into the refrigerator.
However, according to an interview with the Japanese Canned and Bottled Retorted Foods Association by the Japanese daily life website "grape", it is better to store the cans in other containers after opening, as this is safer.
Because once a can is opened, microorganisms will enter the can from the outside, and the contents will easily spoil due to contamination by foreign microorganisms. However, different types of food have different spoilage rates.
In addition, if it is a tinplate can or tin can without an inner coating, and the food is still in the can, the air in the can will make it easier for the tin to dissolve into the food.
Therefore, be sure to transfer it to a glass, ceramic or plastic container and store it in the refrigerator.
But if there is a coating inside the can, which can prevent metal from dissolving, it is better to consider placing the can directly in the refrigerator.
Even if it is placed in the refrigerator, the shelf life is only about 2 to 3 days. It is still recommended that it is best to eat it at the same time, and do not refrigerate it for more than 3 days if you cannot finish it.
If you want to store it for a longer period of time, you need to slightly heat (sterilize) it before storing it.
Things you must do before opening a can to avoid contaminationAccording to the food website Mashed, although eating cans is simple, many people may make a key and potentially dangerous mistake when using them: not cleaning the lid of the can before opening it. Cleaning the outer can is as easy as wiping it down with a clean paper towel, washcloth, or disinfecting wipe.
Because cans may be contaminated with a lot of dust and dirt during the process from factory production to supermarket shelves. Although the food inside the can is protected, the top of the can can come into contact with all kinds of dirt, dust, dirt and other unhygienic materials, leaving behind harmful microorganisms and bacteria. If the outside of the can is not wiped first, these bacteria and microorganisms may enter the food after it is opened and cause disease.
Canned food still has nutritional valueIn addition, many people may have the myth that canned food must be unhealthy. In fact, this is not entirely true. Food experts and nutritionists point out that canned food still has its value, and the main contents are selected, such as beans, fish, canned tomatoes, etc., which are very nutritious. But beware of products with no added salt or low sodium.
