Colorful colored plastic packaging bags belong to recycled plastic packaging bags. The colorant that makes this plastic packaging bag bright contains a substance called benzopyrene. This substance is a strong carcinogen, which may be transferred to food after contact with food.
Under the gorgeous appearance of this plastic bag, there is a heart that destroys your life. Plasticizers can precipitate from the surface of plastic bags, and we will ingest them into our bodies by contacting the food in the bags, causing various hazards to our health. The danger of life is everywhere.
If you buy hot fried dough sticks and steamed buns in the morning, and the plastic packaging bags used by businesses are not up to standard products, there will be more plasticizer precipitation due to the rising temperature! Phthalates are common chemicals in plastic products, which can destroy the production of insulin and increase the risk of type 2 diabetes in the elderly.
Humidity is too high, easy to deteriorate. If the vegetables are placed in plastic bags, the humidity around the vegetables is very high, which is easy to breed bacteria and cause the vegetables to deteriorate. If plastic bags are used, the storage time should not be too long. Lack of ventilation consumes nutrition. In the case of hypoxia, fruits and vegetables will consume a lot of nutrients, producing acetaldehyde and alcohol toxic to cells. Therefore, pay attention to ventilation during storage to ensure oxygen supply.
Jinan plastic bag manufacturers believe that fresh-keeping films should be used for refrigerated and frozen food in refrigerators, rather than ordinary plastic bags. The special process and raw materials of fresh-keeping film have good air permeability and fresh-keeping performance, but ordinary plastic packaging bags can not achieve the purpose of fresh-keeping. Rhizome vegetables are relatively easy to preserve, but they are stored in a cool and ventilated place with mud.
Radish or turnip should be cut off before refrigeration, and then wrapped with plastic wrap and placed in the refrigerator for refrigeration, which can be stored for about 7-10 days. Green peppers will slowly soften if they are directly refrigerated and stored in sealed fresh-keeping bags. Tomatoes should be placed upside down, not stacked.
Fruit should be placed vertically with the pedicled side facing up to reduce vitamin loss. If the peeled fruit is soaked in cold boiled water, it can not only prevent oxidation, but also maintain the original color, making the fruit crisp and sweet.
This is the correct way to open plastic bags. I hope you can understand the above suggestions. For more information, please come to the website https://www.jnsuliao.com Consult.
