Features of deoxidizer packaging
Deoxidation packaging refers to a packaging in which a deoxidizer that can chemically interact with oxygen is enclosed in a sealed packaging container, thereby removing the oxygen in the packaging, and the packaged objects are stored under conditions of very low oxygen concentration or even almost no oxygen. technology. Oxygen is the main factor causing the deterioration of food quality. It can effectively remove the oxygen in the package to achieve a near anaerobic environment, which can inhibit the oxidation of the oil, pigment, vitamin, amino acid, aromatic special and other components in the food, and better maintain the original color, aroma, taste and nutrition of the product; At the same time, the removal of oxygen inhibits the long-term reproduction of aerobic microorganisms, thereby reducing the problem of spoilage and deterioration caused thereby. Therefore, all pests need oxygen to maintain life. If the oxygen in the environment is lower than 0.1%, all the pests can die within half a month. Although the use of a vacuum packaging machine for packaging or inflatable packaging can solve the problem of oxygen influence, this mechanical deoxidation method still has 2% to 3% of oxygen remaining in the packaging, and cannot remove the oxygen infiltrating the packaging from the external environment. It will still be oxidized, stale and stale; and the deoxidizer can completely remove the oxygen in the package, and can also remove the oxygen dissolved in the liquid or filled in the micropores of the solid sponge-like structure from the outside world. , so as to effectively control the various spoilage changes caused by oxygen in the food in the package and reduce it to a minimum. Deoxygenation packaging is widely used in the storage and maintenance of food brands in Japan, Europe and the United States and other developed countries. Enclosed deoxidizer packaging is a new type of packaging formed after the emergence of vacuum packaging and inflatable packaging. It overcomes the shortcomings of vacuum packaging and inflatable packaging that are not completely deoxygenated. At the same time, the technology requires simple equipment, convenient operation, high efficiency, and use. flexible. Deoxygenation packaging has advantages unmatched by other packaging technologies: 1. Improve safety. By encapsulating deoxidizers in food packaging, it is not necessary to add chemical additives such as anti-mildew or anti-oxidation in the food production process, thereby making food safer and beneficial to people's health. 2. Protect food quality. The use of suitable deoxidizers can reduce the amount of oxygen in the package to 0.1%. The food is stored in an environment close to anaerobic, which can prevent the oxidation of nutrients such as oils, pigments and vitamins, and better maintain the original food. Some color, aroma, taste and nutrition. 3. Resist the proliferation of microorganisms. Deoxygenation packaging is more effective than vacuum packaging and air-filled packaging to prevent or delay spoilage caused by oxygen microorganisms, so it can appropriately increase the water content in food (such as bread) and prolong the shelf life. In production practice, the combination of encapsulated deoxidizer packaging with vacuum packaging and air-filled packaging can improve the effect of food preservation. Zhongshan Kenwei's multi-functional rewinding packaging machine is very suitable for use in industries such as deoxidizers and desiccants.
