Not all foods are good for plastic wrap

Cover it with plastic wrap to keep it delicious.

Nowadays, people are becoming more and more dependent on cling film. Vegetables, fruits, leftovers and leftovers, as long as they are covered, they will feel more at ease.

But recently, a study in the United States pointed out that not all foods are suitable for cling film.

33 mg, rapeseed, more lettuce leaves 1.

92 mg.

However, the experimental results of some vegetables are quite different. After 100 grams of cling-wrapped radishes are stored for one day, their vitamin C content is reduced by 3%.

4 milligrams, the beans are reduced by 3.

After 8 mg of cucumber stored for one day and one night, its vitamin C loss is equivalent to 5 apples.

  Cooked food, hot food, and oily food, especially meat, should not be stored in plastic wrap.

Experts point out that after contacting these foods with cling film, it is easy to cause the chemical components contained in the material to volatilize and dissolve into the food, which is not good for health.

Most of the plastic wraps currently on the market are made from vinyl masterbatches as well as commonly used plastic bags.

Some plastic wrap materials are polyethylene (PE). This material does not contain plasticizers and is relatively safe to use. Some materials are polyvinyl chloride (PVC). This material is often added with stabilizers and additives.Raw materials such as auxiliary processing agents are harmful to the human body.

Therefore, care must be taken in choosing.

  Today, there are many urban surface food packaging products, such as some plastic wrap, plastic bags, plastic containers, etc.

Dong Jinshi pointed out: “Preservation is mainly ‘water retention’, ‘quality preservation’ and ‘protection of nutrition’. In this regard, the effect of cling film is the best.

Qualified cling film has strong air permeability, and the oxygen inside and outside can communicate, which can effectively prevent the breeding of anaerobic bacteria, and can ensure food freshness within a certain time.

“But for foods like steamed buns, it seems inconvenient to use plastic wrap. For reference, the plastic wrap is relatively thick, the air permeability is not very good, it is relatively suitable, but try not to close the mouth when using it.

The role of the fresh-keeping box is mainly sealing, which can effectively isolate and store raw food and make the refrigerator space larger.
