The manufacturers of self-supporting zipper bag introduced that coliform group and total bacterial count in food exceeded the standard
One is the poor sanitation of production environment; the other is that the operators do not pay attention to personal hygiene.
Some vacuum packaged cooked food only exhausts the air in the packaging, which does not mean that the vacuum packaged products are sterile products. Only after the complete sterilization process can the food quality be truly guaranteed.
Vacuum packaging cannot guarantee safety
Recently, CCTV's "investigation" column conducted food safety tests on packaged cooked food sold on the market, and some of the products exceeded the standard of Escherichia coli. Eating a lot of cooked food with excessive bacteria will cause abdominal pain, diarrhea, vomiting, headache, food poisoning and other symptoms.
Vacuum packaging, box packaging and aluminum foil packaging in the market are all pre packaging. This kind of packing has many kinds, which can be divided into several kinds of packages which can be sold under normal temperature, low temperature and freezing conditions. The safety of food packaging mainly depends on whether sterilization, sterilization and other steps.
In comparison, self-supporting zipper bag manufacturers believe that aseptic packaging or sterilization packaging and other food are safer, with less bacteria content. The so-called vacuum packaging, nitrogen filled packaging and other packaging methods themselves can not play a sterilization role, if there is no sterilization, sterilization procedures, but only air exhaust, then the food shelf life is actually only a few days. Some foods on the market will mark on the package that the product has been sterilized by high temperature or pasteurization. Consumers can pay attention to the relevant marks on the package.
Aseptic packaging becomes the development direction
Any food production and packaging process can not be absolutely sterile. The use of antibacterial polymer packaging materials for food packaging can inhibit bacterial contamination, prolong the shelf life of food and ensure food safety. Therefore, asepsis will become the general direction of food packaging.
"Aseptic" packaging is a method of sterilization and packaging of packaged food by using instantaneous ultra-high temperature sterilization technology in a "sterile" environment. It is packaged with composite materials through different forms of extrusion and composite molding. It has the advantages of better keeping food, prolonging shelf life, saving energy, reducing packaging cost, and easy to realize environmental protection packaging.
Sterilization helps food packaging
Food packaging is an integral part of food products. Self supporting zipper bag manufacturer introduces that sterilizer is an important equipment for food packaging, and food sterilization is one of the main projects in food industry. It protects food and prevents the damage of biological, chemical and physical external factors in the process of food circulation from factories to consumers. Sterilization machine is an important equipment in the food packaging industry. It can kill the microorganisms on the products, packaging materials, packaging accessories and packaging parts to reduce them to the allowable range. Sterilizer is used for continuous sterilization of fruit and vegetable pulp, juice, concentrated juice, milk, juice beverage or similar products. China food machinery equipment network small editor that do the best quality sterilization equipment, help food packaging safety, contribute to the food industry. http://www.ycritai.cn/
