We all know that the use of plastic bags became a habit, but we thought about how much of his pollution of the environment, the following Shenzhen Environmental Protection Co., Ltd. for everyone to introduce the use of environmentally friendly bags of common sense, also welcome you to comment.
Take a look at the concept: plastic is a large number of small molecules, through the covalent polymerization of polymer compounds, it is based on polymer resin as the main raw material, adding the right amount of plasticizer. However, the synthetic plastic polymer is made of polyvinyl chloride, polyethylene, polypropylene, and their small molecules, including vinyl chloride, ethylene, propylene, etc., are toxic. In the process of polymerizing macromolecules into macromolecules, polymers that do not participate in the polymerization and the non-polymerized polymers are neurotoxic and cytotoxic. For example, vinyl chloride monomer can cause severe hepatic angiosarcoma. Of course, some additives, such as plasticizers, stabilizers and colorants, can also be transferred to food during food contact. Some plasticizers such as dicarboxylate and estrogen phthalate characteristics, some do not meet the requirements (see GB / t21661-2008) stabilizers, such as lead stearate, barium, cadmium and other large pair Dangerous body of the body. It is also recalled that plastic bags, especially chlorine-containing plastics, produce two British air pollutants, such as heating and burning, that can be attached to particles, sink into water and soil, and eventually enter the human body through the food chain. Therefore, we should reduce the chance of using plastic bags, or increase the chances of recycling. Can you put the plastic bag in the fridge? After we bought the food, we threw the plastic bag into the fridge. This is wrong.
First of all, plastic bag permeability is not good, if the bag is too much humidity and too little oxygen, will make fruit and vegetable anaerobic breathing, resulting in a lot of alcohol. At the same time, it will lead to the growth of bacteria, greatly reducing the safety and nutritional value of vegetables! Again, toxic and hazardous substances in plastic bags, such as vinyl chloride, small molecules, processing aids, etc., the longer contact with food, food transfer to the food more, so as soon as possible to separate plastic bags and food. How about storing food without plastic bags? You can not use plastic bags. Of course, you might ask the plastic wrap is not it possible? The Frozen film and frozen food can not be packaged with plastic bags, but instead of plastic packaging instead of ordinary plastic bags. Cloth film special process and raw materials have a good breathable fresh performance, ordinary plastic bags can not achieve the purpose of preservation. You may think that plastic packaging is plastic, will have the same small monomer pollution problem? This requires us to pay more attention when buying plastic film, in addition to the price and manufacturers, try to choose the packaging logo PE (polyethylene) material, to avoid PVC (polyvinyl chloride) synthesis of vinyl chloride into the food is dangerous.
Proper storage: different fruits and vegetables in fresh green leafy vegetables: green leafy vegetables, should be sprayed on the leaves of some water, and then into the plastic wrap, fresh layer to 0 ℃ to 8 ℃ storage. In addition, it is best not to store more than 3 days. Fruit: tomato, eggplant, pepper and other vegetables plus a head, can be sprinkled with a little water, wrapped with plastic wrap, directly into the refrigerator, or into the kitchen translucent plastic bags, placed in the ventilation.
