However, if pesticide, chemical fertilizer and veterinary drug residues are left in the soil during planting of the raw crop, food poisoning may occur. In addition, the raw wet noodles are easy to decay in the storage process, wherein bacteria are main microorganisms causing the raw wet noodles to decay, such as pathogenic bacteria, decay bacteria, yeasts, molds and the like, wherein bacillus and staphylococcus are dominant bacteria in the bacteria, bacillus subtilis is the main decay bacteria in the early storage period, staphylococcus aureus is mainly used in the later storage period, molds in the raw wet noodles are mainly aspergillus circulans and aspergillus candidus, and a small amount of yeasts with fermentation energy are also available in the storage process of the raw wet noodles; in addition, the abundant moisture and the abundant starch and protein in the raw wet noodles also provide ideal conditions for the survival of spoilage microorganisms, and the rapid growth and propagation of the spoilage microorganisms are main causes of the raw wet noodles. In addition, in order to prolong the shelf life of the noodles by a small number of manufacturers, certain safety problems can be caused by illegally adding excessive and out-of-range food additives. Therefore, the research on how to kill bacteria in fresh wet noodles, reduce the content of harmful substances in the fresh wet noodles, sterilize and disinfect the fresh wet noodles and prolong the shelf life of the fresh wet noodles is not slow.

At present, a plurality of methods for sterilizing and disinfecting food are available, a common method is to add bacteriostatic agents and preservatives into the food, the method can not only cause chemical residues, but also derive new toxic substances, increase the food toxicity, and cause the chemical residues, so that bacteria can generate resistance, and the treatment difficulty is increased.
