These foods must not be wrapped in plastic wrap

Cling wrap has become indispensable in our lives, and people are becoming more and more dependent on it. As long as vegetables, fruits, and leftovers are covered with it, they will feel more at ease. But recently, a study in the United States pointed out that not all foods are suitable for using plastic wrap. Some foods are actually not suitable to be covered with plastic wrap, because this will affect health.

Apples, pears, rapeseed, leeks and other fruits and vegetables with high water content are suitable for using plastic wrap. Using plastic wrap on these fruits and vegetables can not only keep them fresh for a long time, but also increase certain nutrients in them. In the study, American scientists found that 100 grams of leek wrapped in plastic wrap had 1.33 mg more vitamin C after 24 hours than when not wrapped, and rapeseed and lettuce leaves had 1.92 mg more.

But the experimental results for radishes, cucumbers and beans were completely opposite. After 100 grams of radish wrapped in plastic wrap was stored for one day, its vitamin C content decreased by 3.4 mg, and that of beans decreased by 3.8 mg. After being stored for a day and a night, the loss of vitamin C in cucumbers was equivalent to that of 5 apples.

It is best not to store cooked food, hot food, oily food, especially meat, in plastic wrap. When these foods come into contact with plastic wrap, the chemical components in the plastic wrap material will evaporate and dissolve into the food, causing harm to health.

In addition to plastic wrap, the food packaging products on the market mainly include fresh-keeping boxes and fresh-keeping bags. In terms of "moisture retention", "quality preservation" and "nutrient preservation", plastic wrap is undoubtedly the most effective. However, for foods that are not suitable for plastic wrap, you can use plastic wrap boxes or bags instead.
