Today, a customer asked me, can food sterilization be sterilized after skin packaging ? After searching for relevant radiation sterilization information and combining the characteristics of food vacuum skin packaging film, Fengyuan Skin Packaging Network Information Department It was concluded that foods such as salmon seafood and aquatic products, cold fresh meat and beef can be sterilized by irradiation sterilization after vacuum skin packaging, which has no adverse effects on the skin packaging itself and the packaged food.
Food skin packaging irradiation sterilization concept
Irradiation (or irradiation) sterilization of salmon, seafood, aquatic products, cold meat and beef is to sterilize food (including raw materials) with a certain amount of ultrashort wave ionizing radiation, and use gamma or beta rays produced by the radioisotope Cobal Irradiated packaged food. T 60 and cesium 157. handle. Delay the development of certain physiological processes (germination and maturity) of fresh foods, or carry out insecticidal, disinfection, sterilization, and mildew prevention treatments on foods to extend storage time, stabilize and improve food quality. X-rays, γ-rays and electron rays are commonly used in food sterilization. X-ray-ray generators that produce electrons mainly from electron accelerators and gamma rays are mainly composed of radioactive isotopes. Commonly used radioisotopes are 60 co and 137 cs. Gamma rays are very penetrating. Suitable for internal disinfection of various packaged foods and finished foods. Electron ray penetration is weak. Generally used for sterilization of small package foods or frozen foods, especially food surface sterilization. The temperature of sterilization is basically the temperature of the product itself. Moreover, the US imported raw materials used in food skin packaging film have a great feature is that it has good chemical resistance, so after irradiation, skin packaging The film itself does not have any adverse effects. While vacuum packaging the packaged food, it will not change any of its chemical properties when irradiated, so it has no effect on packaged salmon seafood, aquatic products, cold fresh meat beef and other foods.
Food Skin Packaging Irradiation Sterilization Type
1) Completely sterilized by irradiation
Irradiation of 25 ~ 50 KGy on sealed food can kill all pathogenic microorganisms of damaged food and achieve disinfection effect. Before irradiation, table salt and sodium triphosphate can be added to food to reduce water loss and improve the killing ability of radiation to bacteria. The radiation-sterilized beef, chicken, ham, pork, sausage and fish and shrimp can be stored at normal temperature (21 ℃ ~ 38 ℃) for more than 2 years, and can maintain good color and taste.
2) Irradiation disinfection
The dose of 4-10KGy can effectively inhibit the growth of microorganisms and pathogenic microorganisms that are harmful to public health. It can effectively remove salmonella that is harmful to foods such as meat, dairy products, and egg products that are packaged in vacuum. When irradiated with 5KGy, it can reduce the number of Salmonella by hundreds of millions and kill Salmonella in deep frozen foods.
3) Food sterilization is safe and reliable.
Practice in the world for more than 40 years has proven that vacuum-packed irradiated food has never found any residual radioactive substances, and can maintain the original quality, color and fragrance. In the United States, skin-packed food irradiation has taken space, and astronauts have proven to be harmless to humans. The advantage of irradiated food is that it can be kept fresh for several years after irradiation, which not only sterilizes, but also inhibits and delays the metabolism of the food itself and eliminates the source of food deterioration. Irradiation sterilization can save a lot of energy. Any food skin packaging can be stored in ordinary packaging after being sterilized by irradiation. It can save a lot of materials and energy such as making, freezing and refrigerating. Some refrigerators.
After the above analysis, food packaging can be completely sterilized by irradiation with the correct and reasonable dose .
