Fresh-keeping storage method for pseudosciaena crocea

Abstract

The invention discloses a fresh-keeping storage method of pseudosciaena crocea. The fresh-keeping storage method comprises the following steps of S1, selecting a live fish source, namely capturing live pseudosciaena crocea from an offshore net cage, wherein the specification is about more than 500g / per pseudosciaena crocea; S2, causing coma, wherein the live pseudosciaena crocea is placed in ice slurry with the ice content of 30%, the temperature is -2 DEG C to -3 DEG C, and the pseudosciaena crocea is completely in coma without reaction; S3, pre-cooling: injecting ice slurry with the concentration of 30% into a heat preservation container, adjusting the temperature to be between -2 DEG C to -3 DEG C, and putting the pseudosciaena crocea into the ice slurry for pre-cooling; S4, storage andfresh keeping: putting the pseudosciaena crocea cooled by the ice slurry into a foam turnover box according to a ratio of the ice slurry to the pseudosciaena crocea of 2: 1, and transferring the pseudosciaena crocea into a refrigeration house of 0 DEG C for refrigeration; and S5, transportation: taking out the pseudosciaena crocea refrigerated by the ice slurry, and quickly adding ice bags for air transportation and sending out, wherein after transporting for 24 hours, the ice bags in the heat preservation box are basically not melted, the pseudosciaena crocea body is relatively hard; and bycarrying out precooling, storage and fresh keeping on the pseudosciaena crocea, the freshness and quality of the pseudosciaena crocea are kept.

Description

technical field [0001] The invention relates to the technical field of preservation, storage and transportation of aquatic products, in particular to a method for preservation and storage of large yellow croakers. Background technique [0002] Large yellow croaker, commonly known as yellow croaker, large yellow croaker, and cucumber fish, is a wide-temperature and wide-salt group migratory fish. It is one of the traditional "four seafood" (large yellow croaker, small yellow croaker, hairtail, and squid) in China. It is mainly distributed in the southern part of the Yellow Sea. As far as the east coast of Leizhou Peninsula, it has a very important position in the marine fishery of my country and the western Pacific Ocean. It is the fish species with the highest production of marine fish farming in my country, reaching 226,000 tons in 2019. Large yellow croaker is favored by consumers because of its tender meat, delicious taste, rich nutrition, golden color and orange lips, whi...

Problems solved by technology

[0003] At this stage, there are still many defects in the fresh-keeping storage and transportation technology of aquatic products in my country. Due to factors such as short shelf life, high corruption rate, nutrient loss, and quality decline caused by the circulation link, it is difficult for most chilled aquatic products to form high economic benefits and markets.
