There are many different types of food, and different foods, with different sources of raw materials, are exposed to different natural environments, so the microbial groups that contaminate them can vary somewhat. Overall, it is mainly summarized in the following ways.
1, through the raw material contamination of food
Food is processed from a variety of raw materials through the reasonable deployment of the compound mixture of raw materials, a wide range of different properties, there are oily raw materials, powdered raw materials, gelatinous raw materials, etc., in these raw materials, there are certain fats, proteins and starch. When these nutrients are exposed in space, germs can invade.
2, through the packaging materials contaminated food
The most common food packaging on the market (direct contact with the class of packaging containers) can be broadly divided into paper materials, plastic materials, glass materials, metal materials, ceramic materials, bamboo and wood materials, as well as other composite materials. Packaging materials (barrels, bottles, lids) of the unhygienic is caused by microbial contamination of food is an important reason, the contents of food due to containers and accessories and contamination of microorganisms is not uncommon, the container manufacturer's sanitation may not be able to ensure that the container in the process of production, storage and transportation of cleanliness and hygiene, so the packaging containers should be cleaned and disinfected before use.
3, through the utensils contaminated food
Food utensils, including raw materials, packaging health care products, transportation tools, production and processing equipment and finished product packaging materials and containers, etc., are likely to become a medium of microbial contamination of food, especially the surface of the utensils is not smooth more serious degree of contamination. These utensils should be thoroughly cleaned and sterilized before packing raw materials or finished products to ensure the hygienic quality of finished products.
4, through the air pollution of food
Air microorganisms are temporary, variable, although microorganisms in the air generally do not grow and reproduce, but the air is suspended everywhere with microbial dust, particulate matter or liquid droplets, these microorganisms are from a variety of different sources are brought into the air. These microorganisms are brought into the air from many different sources. There is a lot of dust in the air, and a large number of microorganisms are attached to the dust, and with the flow of air and changes in air pressure, the dust flies or settles, and the microorganisms are attached to the food. In addition, the human body with microbial sputum foam, snot and saliva droplets, in speech, cough or sneeze, may also be directly or indirectly through the air pollution of food.
5, through the personnel contamination of food
The surface of the human body, hair or clothes have many microbial adsorption. When people contact health care products, the human body can be used as a medium to contaminate food with microorganisms. Especially hands, the number of stray bacteria per square centimeter can be as high as a few million, caused by the most common food contamination. If the practitioners in direct contact with food production operations do not wear work clothes and hats or hands and work clothes and hats are not often washed and disinfected to keep clean, it will bring a large number of microorganisms into the food, resulting in food contamination.
How to eliminate microbial contamination of food
In the food production process, disinfection is a systematic project is also a technical work. Production of raw materials, packaging materials, utensils, environment, personnel, equipment, containers, production water and so on to maintain the sterilization, to do no dead ends, to avoid microbial breeding. Choose a suitable disinfectant is essential:
1, need to have a broad-spectrum and efficient bactericidal effect, a disinfection product can kill bacteria, fungi, molds and other pathogenic microorganisms;
2, does not produce bacterial resistance to meet the requirements of the long-term reuse;
3, the requirements of the food-grade disinfectants to achieve the consumption of harmless grade;
4, the requirements of the food industry in the production of raw materials and utensils, the environment, equipment, containers, production water and so on to maintain sterilization to avoid microbial breeding. p>4, required to have proven applications in the food industry;
So are there any sanitizers described above? The answer is yes.
Octitex
Octitex--imported from Germany, food-grade hydrogen peroxide-silver ion composite bactericidal disinfectant, colorless, tasteless, non-toxic, non-residual, non-corrosive and other characteristics of the product through the European Union EMAS testing and certification, the IFS International Food Standards testing and certification, ISO9001\ISO14001 management system certification, TUV Rheinland Certification etc. Its disinfection effect can fully meet the requirements of sterile workshop disinfection, and it has become the first product for daily disinfection in many food production enterprises. Tested by authoritative departments, the killing effect of Octex high-efficiency disinfectant on microorganisms (including spores) is very outstanding. Because of its unique features such as high bactericidal efficacy, safety and no residue, Octex disinfectant has been widely used in actual production. In particular, Octatex has been introduced into many high-end fields at home and abroad, such as food and beverage, biopharmaceuticals, medical and health care, and so on, and has been popularized.
The advantages of Oxytetracycline disinfectant
1, broad-spectrum sterilization: Oxytetracycline has an instantaneous bactericidal properties, capable of killing more than 200 kinds of bacteria, molds and viruses, including: Escherichia coli, Staphylococcus aureus, Streptococcus pyogenes, Bulgarian bacillus, Enterococcus faecium, S. pneumoniae, P. aeruginosa, P. aeruginosa, Pseudomonas aeruginosa, Pseudomonas aeruginosa, microbacterium lactis, bacterium bacillus, Bacillus, streptococcus etc.... , molds, viruses.
2. Oxytetracycline has the feature of no secondary pollution, because Oxytetracycline is through the release of hydroxide bonds, oxidation sterilization, so the residue is only water and oxygen, belonging to the pure ecological disinfection products without secondary pollution.
3, through the addition of silver ions, OCTASIA is different from ordinary hydrogen peroxide, only a small amount of hydrogen peroxide can be used to solve the problem of higher concentrations of ordinary hydrogen peroxide to solve the problem, successfully solved the problem of poor stability and corrosiveness of hydrogen peroxide.
