Choose a suitable fresh-keeping package and do not let the plastic wrap become a poison
Cooked foods should not be wrapped in plastic wrap
Today, people rely more and more on cling film, vegetables, fruits, leftovers leftovers, as long as cover it, my heart will be a lot of practical. However, a recent study in the United States pointed out that not all foods are suitable for cling film. People use cling film in order to preserve the quality of food in order to facilitate food safety and health, but never thought that if the cling film is used improperly, it will make the food poisonous.
Plastic wrap has different effects on different fruits and vegetables
Fruits and vegetables with higher moisture content are more suitable for cling film, such as apples, pears, tomatoes, canola, quail yellow, etc., not only can keep freshness, but also increase some of the nutrients. Experiments show that 100 grams of glutinous rice cake wrapped with plastic wrap, after 24 hours, the vitamin C content was 1.33 mg more than when it was unwrapped, and rape and lettuce leaf were 1.92 mg more. However, the experimental results of some vegetables are quite different. After 100 grams of radish wrapped with plastic wrap, the content of vitamin C was reduced by 3.4 mg and the amount of 3.8 mg of dried beans was reduced. Once the cucumber is stored for one night, the amount of vitamin C lost is equivalent to 5 Apples.
Cooked foods should not be wrapped in plastic wrap
Cooked foods, hot foods, foods containing oils, especially meats, are best not to be packaged and stored in cling film. Experts point out that after these foods come into contact with the plastic wrap, they can easily evaporate the chemical components contained in the materials and dissolve into the food, which is not good for health. Most plastic wraps currently on the market are made from ethylene masterbatch as well as common plastic bags. Some plastic wrap materials are polyethylene abbreviation PE, this kind of material does not contain plasticizer, it is relatively safe to use some; Some materials are polyvinyl chloride abbreviated PVC, this kind of material often adds stabilizer, lubricant, auxiliary processing agent Raw materials, etc., have some harm to the human body. Therefore, we must be cautious in our choice.
Choose the right fresh-keeping package
Today, there are many food packaging products on the market, such as plastic wrap, fresh-keeping bags, and crisper boxes. Preservation is mainly to preserve water, preserve quality and protect nutrition. In this regard, cling film works best. Qualified plastic wrap is highly air permeable, and internal and external oxygen can be exchanged, effectively preventing the growth of anaerobic bacteria, and ensuring food freshness within a certain period of time. However, for food such as steamed buns, it is obviously inconvenient to use plastic wrap. Compared with fresh wraps, the freshness of the wrap is relatively thick, and the air permeability is not very good. It is relatively suitable, but try not to seal the mouth when using it. The function of the crisper is mainly sealed, which can effectively store the raw and cooked foods in isolation and increase the space utilization of the refrigerator.
