A U.S. company launches a new type of refrigerator freezer bag

Foods that are frozen in refrigerators can prevent them from deteriorating, but they also cause deterioration in the color, smell and taste of foods. Especially when refrigerators store foods such as pork and poultry meat, deep freezing can destroy the structure of the meat and cause it to fade. Meat color, tasteless. How to prevent the refrigerator from destroying delicious food due to improper freezing? A manufacturer of household vacuum packaging machines in San Francisco, USA, recently announced that its packaging, called "Friends of Food," can better prevent food from freezing in refrigerators. This conclusion is based on experimental research conducted by another independent microbiological technology research institution. Research shows that foods vacuum packed with “Friends of Food”
Its ability to resist freezing is much better than the reusable plastic food bags that are widely used today.
In order to test the performance of the bags, they used chicken and beef as experimental objects, and they were packaged under the vacuum temperature of “Friends of Food” bags and two kinds of refrigerator bags commonly used in the market, and they were commonly used at the freezing temperature of household refrigerators. Compare the preservation experiment, the experiment result is:
After four weeks of freezing, chicken and beef preserved in a vacuum packaged by "Friends of Foods" have no weight loss, no ice chips on the bag wall, no obvious discoloration, etc., and chicken and beef packed in other two types of refrigerator storage bags. The weight was significantly reduced, the walls of the bags were frozen, and freezing was observed with the naked eye two weeks after freezing.
“Friends of Food” is a fresh-keeping bag designed and produced by the company for a vacuum packaging machine.
The advantage is to make full use of commercial-grade vacuum to preserve foods so as not to be oxidized by direct exposure to the air. It consists of three walls, one of which is nylon for increasing strength. The wall of the bag is also equipped with a suction channel, which is the company's patented technology that makes vacuum packaging easier. The "Friends of Food" vacuum bag is resistant to freezing and can be heated in a microwave. It can also be boiled, washed or resealed.
“Friends of Food” vacuum packaging bags and vacuum packaging machines can keep foods frozen for 3 to 5 times longer than normal storage bags. This technological achievement will change the way food is preserved in the kitchen.
