Antibacterial packaging film for meat products

in the circulation process of meat products from factories to consumers, there is a high chance of microbial contamination. The direct way to curb pollution is packaging. The function of packaging or the special significance of packaging film is to isolate products from external pollution sources. Suppliers of packaging equipment and materials are focusing on improving the packaging system in order to more effectively curb microbial contamination of meat products

bacteriostatic packaging can be achieved by changing the gas composition in the packaging system (modified atmosphere packaging) or adding food grade additives (bacteriostatic material packaging) to the packaging materials. Its main advantage is that it can inhibit microbial activity and prolong the shelf life of meat products. Modified atmosphere packaging is to put meat products in the package, and then fill it with gases that can inhibit the growth of bacteria, such as carbon dioxide or nitrogen, and reheat the package. The disadvantage of modified atmosphere packaging is that once the packaging is broken, the product will lose protection

bacteriostatic material packaging refers to coating natural or synthetic bacteriostatic ingredients on the packaging surface or injecting them into the packaging film. These components include: enzymes, organic acids (lactic acid, sorbic acid), EDTA and other metal chelators, lauric acid and other short chain fatty acids, silver ethanol and zinc combined with zeolite. Different kinds of meat should be added with different inhibitors

after the meat products are packaged, the antibacterial ingredients are transferred from the packaging to the products or between the meat products and the packaging to kill bacteria or minimize the reproduction of bacteria. Because the concentration of antibacterial ingredients added is very low, it will not affect human health

the combined components of metallic silver and zinc and zeolite are most commonly used in the packaging of antibacterial materials. These components can be combined with cloth, paper, composite bags and other materials. Zeolite has a complex chemical structure, which can adsorb ions, such as zinc and silver, and then slowly release them into the environment. When the packaging film comes into contact with meat, if the boiling does not meet the requirements, the silver and zinc ions released by orthoclase should be found again to disturb the normal biological activities of microbial cells. Polycarbonate and Harbin University of technology have established a graphene utilization technology laboratory. At the same time, zeolite converts the oxygen in the packaging into ozone, a reaction form of oxygen that can inhibit the growth of microorganisms, which also has an impact on the growth of microorganisms. A few years ago, Japanese food technicians developed a cloth containing zinc and silver zeolite compounds for household preservation of fresh meat or poultry products. After 2000 washes, the effect of this cloth will not weaken

horseradish extract is another natural anti microbial component, which can be combined with the packaging film, but the packaging film must be made of materials that can be prepared for the experiment to make the horseradish components volatilize fully for a certain period of time. After volatilization, horseradish extract fills the space between packaging materials and meat products to kill bacteria. Because the extract has a strong spicy taste, the packaging film containing horseradish extract cannot directly contact wet products. Meanwhile, horseradish extract is particularly effective in inhibiting mold and yeast, so it is especially suitable for beef jerky products. Another ingredient that can effectively inhibit mold and yeast is mustard extract, which also has an effective inhibitory effect on Gram-negative bacteria

like other new technologies, the use cost of bacteriostatic film is higher than that of traditional packaging materials, but as people understand its role more and more, the high cost will not become a major obstacle to its future application
