[Chinese Packaging Network News] Zhou black duck under normal bare storage, even if placed in a 0-4 degree refrigerated environment, in a very short period of time there will be deterioration, deterioration, corruption, or a variety of colonies exceeded, causing food Unsafe risk. Zhou Heidian modified atmosphere packaging used fresh modified atmosphere packaging, modified atmosphere packaging is a new way of food packaging. Suitable for cooked foods, cold meats, poultry and other meat foods that are not easy to keep fresh, put the food in the box, replace the natural air in the box with a certain percentage of fresh air, through the choice of packaging materials, good The sealing process extends shelf life and shelf life at refrigerated temperatures. The causes of corruption in Zhou black duck are: 1. Excessive amounts of microorganisms cause protein denaturation, resulting in various kinds of spoilage. 2, rancidity, most foods contain nutrients such as oils, proteins, etc. These components are oxidized in the presence of oxygen or decomposed by microorganisms or high-temperature oxidation, resulting in small molecules of acid, and release a unique odor, resulting in The acid value of food exceeds the standard and rancidity occurs. In severe cases, it will irritate the pungent hazel flavor. 3. Physical packing of food molecules caused by physical compression of vacuum packaging, frozen packaging, etc. may also cause variation in the taste of food. So how is modified atmosphere packaging to avoid this? For Zhouzao deli fresh locks, a mixture of carbon dioxide and nitrogen is usually used to replace the natural air inside the box, so that the oxygen content in the box is reduced to the limit, so that the well-being bacteria grow under such circumstances. Suppressed. At the same time, more than 20% of the concentration of carbon dioxide will also inhibit the growth rate of most bacteria, the growth of bacteria will be slow, and the preservation period will naturally be extended. After the modified atmosphere fresh-keeping package, the black ducks are locked in fresh containers, and the oxygen content in the package is extremely low, which also avoids the rancidity of the food. At the same time, fresh airlocks can be used for packaging, not squeezing aromatics in foods and foods, causing physical changes in foods, and not affecting the taste of foods as much as possible to maintain the original ecological taste.
