Ice-temperature fresh-keeping method for large yellow croakers

Abstract

The invention relates to an ice-temperature fresh-keeping method for large yellow croakers. The method comprises the following steps: 1) pre-treatment; 2) cold sterilization; 3) pre-cooling by fluidized ozone ice; 4) injection of a freezing point conditioner for fish bodies; and 5) packaging and insulating. The method provided by the invention has the following advantages that 1, during packaging, the temperature of the fish bodies is reduced by ozone ice which has a remarkable sterilizing effect and can remarkably inhibit deterioration of the fish bodies; 2, the large yellow croakers are pre-cooled by using the fluidized ozone ice, and the fish bodies are fully immersed in the ozone ice, so that not only can physical damage to the surfaces of the large yellow croakers be reduced, but also oxygen can be isolated, thereby preventing oxidization; 3, on the basis of the ozone ice and fluidized ozone ice, ice temperature storage is adopted, and the three ways are combined to realize the collaborative effect, thereby effectively inhibiting activities of microorganism and conversion of various enzymatic activities; 4, the process of the freezing point conditioner entering into the fish bodies is greatly improved by way of injection.

Description

technical field [0001] The invention relates to an ice temperature preservation method for large yellow croaker. Background technique [0002] Large yellow croaker belongs to the order Perciformes, and belongs to the family Scrotoaceae, commonly known as yellow croaker, also known as yellow croaker, big fresh, and big yellow flower. one. It has a very important position in the ocean fishery in the western Pacific Ocean, and now it is one of the six famous and high-quality aquatic products that our country has a high reputation and competitiveness in the international market.

Problems solved by technology

[0003] Due to the processing characteristics of large yellow croaker and people's consumption habits, more than 90% of large yellow croakers are circulated and sold in the form of chilled whole fish. In the actual production and distribution process, the shelf life of large yellow croaker is only more than ten days, which is seriously limited by the short shelf life. The sales market of large yellow croaker
