Many people understand that the vacuum fresh-keeping bag puts the food in the tape, and then vacuumizes it. In an environment without air, microorganisms cannot survive and achieve the effect of fresh-keeping. How many people know how to use the vacuum preservation bag safely and correctly?
Follow the instructions, but why doesn't it achieve the effect of preservation? These are common problems.
Vacuum preservation bags How can we better understand some of the safety issues of vacuum preservation bags? I believe that many of us in the current society have not understood these factors from the front, nor have we summarized them from the daily life around us. Everyone's index requirements for health and safety have also increased. For such a situation, here are a few safe methods for using vacuum preservation bags:
1. Do not use vacuum bags to pack alcoholic foods: Alcoholic foods and oily foods will dissolve the lead in the polyvinyl chloride plastic bag into the food, and this plastic vacuum bag cannot hold food with a temperature above 50 degrees. In addition, consumers should use special food vacuum packaging bags for food, especially plastic vacuum bags with a particularly dark color, which are likely to be reprocessed from recycled plastic vacuum packaging materials and should be resolutely avoided for food packaging.
2. Do not use ultra-thin plastic vacuum bags: ultra-thin plastic vacuum bags are light in weight and thin in thickness, but their load-bearing capacity is very strong. This is because plastic vacuum bag manufacturers have added plasticizers during the production process. Plasticizers are extremely harmful to human health, and national laws and regulations also prohibit manufacturers from producing and selling ultra-thin plastic bags.
3. Minimize the use of unprocessed vacuum bagged cooked food: Unprocessed vacuum bag packaging of cooked food often causes food deterioration. After eating, food poisoning symptoms such as vomiting and diarrhea are likely to occur. In addition, the untreated vacuum bags themselves will release harmful lifts. If they accumulate in a sealed environment for a long time, their concentration will increase with time, which will contaminate the food in the bag and affect human health, especially for children. It has a prominent impact on healthy development.
