Problems solved by technology

However, the moisture content of degreased large yellow croaker in this method is lower than that of chilled large yellow croaker. Although it is beneficial to freshness to a certain extent, it causes the loss of some fat-soluble flavor substances, and the reduction of water makes the large yellow croaker taste poor when eaten.

Abstract

The invention discloses a method for quick-freezing and fresh-keeping of large yellow croaker, which belongs to the technical field of fresh-keeping of aquatic products. The method for quick-freezing and fresh-keeping of large yellow croaker comprises the following steps: packing freshly caught large yellow croaker in a manner of stacking crushed ice and large yellow croaker, The crushed ice used is made of an aqueous solution containing food-grade hydrogen peroxide, sodium citrate and citric acid; remove the viscera, gills and scales of the large yellow croaker and clean them; soak the large yellow croaker in the first fresh-keeping solution for 7-12 minutes; After the film is formed, put it into the second fresh-keeping solution and soak for 2-5 minutes; then freeze it with liquid nitrogen. The quick-frozen and fresh-keeping method for large yellow croaker provided by the present invention can kill bacteria on the body surface of large yellow croaker, form two layers of protective films on the surface of the large yellow croaker, avoid contamination of large yellow croaker by miscellaneous bacteria, effectively slow down the speed of fat oxidation, and protect the large yellow croaker body The color of the surface avoids the loss of water during freezing and storage, ensures the freshness of the large yellow croaker after freezing, and improves the time and effect of the large yellow croaker’s frozen freshness.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of aquatic products, and in particular relates to a quick-freezing and fresh-keeping method of large yellow croaker. Background technique [0002] Large yellow croaker, Osteichthyes, Perciformes, Totoaceae, Yellow croaker, also known as yellow croaker and large yellow flower, is one of the four traditional marine economic fish in my country. Large yellow croaker is deeply loved by consumers because of its rich nutrition, tender meat and delicious taste. However, due to overfishing in marine fisheries, the production of wild large yellow croaker has been decreasing year by year. Almost all large yellow croakers sold in the market are artificially farmed large yellow croakers. Large yellow croaker is the largest marine fish cultured in my country, and artificial breeding is mainly concentrated in Fujian Province, Zhejiang Province and Guangdong Province also have a small amount of breeding. ...
