Kitchen Knowledge: Put the dish into the refrigerator and remove the plastic bag

When we came back to buy the dishes, we used to throw the plastic bags inside the refrigerator into the refrigerator. However, this move may have potential health hazards.

First of all, some plastic bags do not have good air permeability. If the humidity inside the bag is too high and the oxygen content is too low, anaerobic respiration will occur in fruits and vegetables, resulting in a lot of alcohol. At the same time, it will also cause bacterial growth, greatly reducing the safety and nutritional value of fruits and vegetables. Second, colorful colored plastic bags belong to recycled plastic bags, and do not rule out the possibility that the used colorants contain benzopyrene (a strong carcinogen) that may be transferred to food after contact with food. Again, if the production process is not closed, the plasticizer precipitates from the surface of the plastic bag, and the human body may ingest the product into the body by contacting the bag and may also cause harm to the human body.

Without plastic bags, what should we do? The correct way is to use plastic wrap. The special process and raw materials of cling film have good air permeability and preservation performance, and the quality of the cling film does not have the problem of contamination of small molecules. When purchasing, you should choose the outer packaging label PE (polyethylene) material. The identification method is: look at the color, the yellow color of the whole roll is PVC material, and the white material is PE material. Second hand rub, PE cling film is generally less viscous, easy to open after hand rub, and PVC cling film is sticky, easy to hand rub. If it is a green leafy vegetable, water can be sprayed on the leaves and placed in a plastic wrap. The fresh-keeping layer is stored at 0°C to 8°C for storage. It is better not to exceed 3 days. Tomatoes, eggplants, peppers and other vegetables with pedicles can be sprinkled with a little water, wrapped in cling film, placed directly in the refrigerator, or placed in a translucent plastic bag in the kitchen, placed in a ventilated place.
