Quick-frozen foods are a kind of food processed by rapid low temperature (below -18 °C). The moisture and juice in the food will not be lost, and at such low temperatures, the microorganisms will not multiply. Therefore, using the quick-frozen method to process food can effectively improve the flavor and nutritional value of the food, and improve the safety and quality of the food.
Some people think that since the growth of microorganisms in the low temperature state is hindered, it is not necessary to strictly control the sanitary conditions of the workshop in the production process of quick-frozen food. So, is this correct?
Zhou’s legislative engineer of Shanghai Kangjiu Disinfection Technology Co., Ltd., which specializes in developing food quality assurance technology, believes that this statement is wrong. Although quick freezing can inhibit microbial reproduction, if the production environment is poorly sanitized, the microbiological indicators of quick-frozen foods will still exceed the standard, which will lead to a decline in food safety.
In order to improve the safety and quality of frozen food, Fujian Yuweixiang Food Frozen Food Co., Ltd. installed a pipeline type dual-core ozone generator to transport ozone to each workshop. It is reported that the pipeline ozone generator is an industrial ozone generator, which effectively prevents the deterioration of frozen foods, prolongs the shelf life of frozen foods, and promotes the development of enterprises.
The ozone generator is a kind of ozone generating machine, which is divided into three types according to the principle of ozone generation. The ozone generator is mainly divided into three types: a high-pressure discharge type ozone generator, an ultraviolet irradiation type ozone generator, and an electrolytic type ozone generator. The dual-core ozone generator is manufactured by a high-pressure discharge type, which uses a high-frequency current of a certain frequency, and then generates a high-voltage corona electric field to electrochemically react oxygen molecules in or around the electric field to generate ozone.
According to the weekly legislative engineer of Shanghai Kangjiu Disinfection Technology Co., Ltd., a high-efficiency ozone disinfection machine with dual-core ozone generator has the characteristics of mature manufacturing technology, stable work, long service life, large ozone output and high sterilization efficiency. In the process of food production and storage.
Yuweixiang Food Company has a large workshop area. The company uses a dual-core industrial ozone sterilizer to transport ozone to each food shop through PVC pipes to improve the sanitation of each workshop. The general manager of Yuweixiang Food has a clear understanding of the role of ozone sterilization machine. After communicating with Shanghai Kangjiu Disinfection Company, the food company purchased several ARD-S200 industrial ozone generators to sterilize the food workshop and achieved obvious bactericidal effect. After being combined with other food quality assurance measures, it effectively avoided The occurrence of microbial over-standard problems has prolonged the shelf life of food.
Pipeline dual-core ozone sterilization technology can improve the safety and quality of quick-frozen foods, and has been praised by many food enterprise customers. Due to the remarkable ozone sterilization effect, it can obviously prevent food deterioration caused by microorganisms and improve food safety and quality. Therefore, many food enterprises in the country have installed dual-core ozone disinfection machines in food cooling and food packaging workshops.
The sterilization of the dual-core ozone generator is mainly due to the strong oxidation of ozone. Ozone sterilization includes three forms: 1. Ozone oxidizes the enzymes required to break down the internal glucose of the bacteria, inactivating and dying the bacteria. 2. Ozone directly acts with bacteria and viruses, destroying their organelles and DNA and RNA, destroying the metabolism of bacteria and causing the death of bacteria. 3. Ozone penetrates the cell membrane tissue, invades the cells, acts on the outer membrane lipoprotein and the internal lipopolysaccharide, causing the bacteria to undergo permeability distortion and dissolve and die.
Quick-frozen food refers to rice, noodles, miscellaneous grains and other main raw materials, and meat, vegetables and other auxiliary materials. After processing into various kinds of cooked or uncooked staple foods, they are quickly frozen and processed to freeze. Foods stored, transported and sold under conditions, such as quick-frozen dumplings, quick-frozen dumplings, quick-frozen steamed buns, quick-frozen dumplings, frozen frozen rolls, frozen spring rolls, etc.
The development of the frozen food processing industry can digest a large amount of grain and oil materials, improve the processing conversion rate and added value of grain and oil agricultural products, increase farmers' income, promote rural economic development, enrich the food varieties of residents, optimize food structure, and maintain social stability. It is also of great significance.
With the increase of economic income and the accelerated pace of life, the time spent by the general public on food cooking will be reduced accordingly. Convenient and quicker will be the development trend of kitchen cooking in the future. Convenience food will enter more and more family kitchens. . This is both an opportunity and a challenge for fast food enterprises in the convenience food category. Quick-frozen food companies can only improve their production processes and adopt food-grade equipment such as dual-core ozone sterilizers to improve the quality and production efficiency of quick-frozen foods, so that they can gain a firm foothold in the fierce market competition and move forward steadily.
