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. Studies have shown that foods vacuum-packed with “Friends of Food” are much more resistant to freezing than freshly 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. The comparison experiment of preservation was carried out. The experimental results were: After four weeks of freezing, chicken and beef preserved in a vacuum package with “Friends of Food” were free from weight loss, there was no ice flakes in the bag wall, no obvious fading and other deterioration phenomena, and the other two were used. The chicken and beef packaged in a refrigerator bag had a markedly reduced weight, and the bag walls were frozen, and frozen maceration that was visible to the naked eye was observed after two weeks of freezing.
“Friends of Food” is a fresh-keeping bag designed and produced by the company for a vacuum packaging machine. Its advantage is to make full use of commercial-grade vacuum to store foods so as not to be oxidized by direct exposure to air. It consists of three walls, of which, A layer of nylon is used to increase 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.
