Research on the International Refrigeration Society shows that the food corruption deterioration caused by various reasons in the world accounts for 45%of the annual output due to various reasons. Biological factors are the main aspects of food deterioration, while bacteria, mold, etc. are the main microorganisms of food corruption and deterioration; Fruit, raw leaves, fish, meat and other foods will cause corruption in room temperature for about 2 days.

  External cause: First, microorganisms pollute food. After microorganisms are polluted by food, these microorganisms must survive and breed quickly on food under the condition of suitable conditions. During its reproduction, the food must be constantly decomposed to ingest the nutrition and self -surviving energy, so that the nutrients in the food will continue to degrade some complicated and biochemical reactions under the action of microorganisms, which changes the sensory traits of the food. Essence At the same time, microorganisms must be metabolized in the process of survival, and some of the metabolites are toxic. This makes the food completely lose its edible value.

   The second is environmental reasons. Another important external cause of food corruption and deterioration of food storage for food storage.

     Temperature; because the vast majority of microorganisms are difficult to survive or slow down, and stop breeding at high temperature and low temperature, they can no longer decompose food. The most suitable temperature for most microorganisms to survive is between 30 ° C-40 ° C, so Fresh foods can be kept in a short time below 0 ° C, and food can be saved for several years when below minus 24 ° C. However, when the ambient temperature exceeds 40 ° C, most microorganisms are difficult to survive, or slow down or stop their reproduction. Most microorganisms were killed when the ambient temperature was higher than 65 ° C. Therefore, the food that has been treated with high temperature can be appropriately extended the preservation period. humidity. In addition, all microorganisms are like other creatures. Survival cannot be separated from water. If the water content in the environment is extremely low, microorganisms cannot survive. Therefore, dry foods can be stored for a long time, such as dry sea cucumber and fungus.

        At present, due to the lack of attention from food processing enterprises in China to the environment in the environment, various food poisoning and resources of resources are countless.

          Plasma air purification equipment can quickly kill harmful microorganisms in the food processing workshop and food storage library, such as viruses, bacteria, mold, fungi, floating dust in the air and eliminating odor molecules in the air. The natural evaporation of water, efficiently improve the freshness and freshness of food, make foods not easy to deteriorate and mold, thereby ensuring the quality and safety of food. During the fresh -keeping storage process, due to the sharp optimization of air quality, the temperature of the freezing air inside the storage room can be appropriately increased, so that the power consumption of the air conditioner can be clearly saved by about 35%.
