Cover with plastic wrap to lock the deliciousness. Nowadays, people are increasingly dependent on plastic wrap. Vegetables, fruits, leftovers and leftovers, as long as they are covered, will feel more at ease. But recently, a study in the United States pointed out that not all foods are suitable for use in plastic wrap.
Fruits and vegetables with higher water content are more suitable for use in plastic wrap, such as apples, pears, tomatoes, rape, leeks, etc., which can not only keep fresh for a long time, but also increase some of the nutrients. Experiments have shown that 100 grams of leek wrapped in plastic wrap is supplied in Dongguan stretch film. After 24 hours, its vitamin C content is 1.33 mg more than when it is not wrapped, and rape and lettuce leaves are 1.92 mg more. However, the experimental results of some vegetables are quite different. After 100 grams of radish wrapped in plastic film is stored for one day, its vitamin C content is reduced by 3.4 mg, and beans are reduced by 3.8 mg. After cucumber is stored for one day and night, its vitamin C loss is equivalent to 5 Apples.
Cooked food, hot food, fat-containing food, especially meat, it is best not to store them in plastic wrap. Dongguan Stretch Film Supply | International Food Packaging Association Vice President Dong Jinshi pointed out in an interview with reporters that after contacting these foods with plastic wrap, it is easy to volatilize the chemical components contained in the material and dissolve into the food, which is harmful to health. Like the commonly used plastic bags, most of the cling films currently on the market are made of ethylene masterbatch. Some cling film materials are polyethylene (referred to as PE), which does not contain plasticizers and is relatively safe to use; some materials are polyvinyl chloride (referred to as PVC), which often add stabilizers and lubricants , Auxiliary processing agents and other raw materials are harmful to the human body. Therefore, we must be careful in choosing.
Nowadays, there are many food packaging products on the market, such as cling film, fresh-keeping bag, fresh-keeping box, etc. Dong Jinshi pointed out: "Preservation is mainly about water retention, quality retention, and nutrition protection. In this regard, the cling film has the best effect. The qualified cling film is highly breathable, and the internal and external oxygen can communicate, effectively preventing anaerobic bacteria. Breeding, within a certain period of time, the food can be kept fresh." But for foods like steamed buns, it is obviously inconvenient to use plastic wrap. In comparison, the fresh-keeping bag is thicker and the air permeability is not very good. It is relatively suitable, but Try not to seal the mouth tightly when using. The function of the fresh-keeping box is mainly to be sealed, which can effectively isolate the raw and cooked foods and increase the utilization rate of the refrigerator space.
