        1. normal fresh-keeping bags or films shall be used for fresh-keeping of fruits and vegetables as far as possible. Normal and qualified fresh-keeping bags or bags have good air permeability and safety. Oxygen can circulate, which can effectively prevent the propagation of anaerobic bacteria, while ordinary plastic bags can not achieve the purpose of fresh-keeping.

         

        1. ordinary plastic packaging bags should not be heated in the microwave oven as far as possible. Ordinary plastic films contain plasticizers, which are easy to release during the heating process. When heating food in a microwave oven, the packaging container with "special for microwave oven" shall be selected.

         

        1. do not put a plastic bag in the bowl to contain hot food. To save time, some vendors on the roadside often put a plastic bag on the bowl to contain hot and sour powder, bean curd, small noodles, and other food. This is very unhealthy behavior. Harmful substances in plastic bags are easy to be separated in case of high temperature and grease, which is not conducive to health.

         

        1. do not use plastic bottled oil. Try to use glass, ceramics, stainless steel, and other containers to hold edible oil.

         

        Finally, it is recommended to use fewer or no plastic bags for food, especially for hot or hot food. From the perspective of environmental protection, it is recommended to bring their own environmental protection shopping bags when shopping, reduce the use of plastic bags, and pay attention to the classification and recycling of garbage bags. If you have used plastic bags to contain food before, don't worry too much. As long as the harmful substances do not exceed the national standards, they will not cause damage to the human body. In addition, the human body has the metabolic function of plasticizers and other harmful substances. As long as they are not consumed in large quantities for a long time, don't worry too much.
