Aquatic product sterilizing pre-treating and cold-preserving method

The invention discloses an aquatic product sterilizing pre-treating and cold-preserving method. The method comprises the steps of: firstly, washing an aquatic product by cold water to remove dirt and impurities; secondly, soaking the washed aquatic product in sub-acid electrolysed water or stirring for sterilization; placing the sterilized aquatic product in a foam preservation box and covering the sterilized aquatic product with preservation ice; and finally sealing the box. By using the method, the spoilage caused by microorganism pollution can be effectively restrained and the shelf life of the aquatic product can be prolonged; the preservation ice can be used for lowering the temperature and slowing down a series of biochemical reactions of the aquatic product; the water formed by melted ice during storage and transportation can play a further sterilization role; the sub-acid electrolysed water has a broad spectrum and high-efficient sterilization effect and especially can be reduced to water after reacting with organic matters; compared with the current other sterilizing agents, the sub-acid electrolysed water is safe without residues and is friendly to human bodies and environments; and the sub-acid electrolysed water is moderate in reacting functions and hardly has influences to the quality of meat. The method is not only applicable to preservation of fresh foods such as fish, shrimps and shellfish, but also applicable to the preservation field of meat products.
