Problems solved by technology

At present, the commonly used large yellow croaker quick-freezing process is to pack the large yellow croaker directly into the flat plate freezer, and store it in the cold storage after freezing. This processing method will cause: 1. Protein freezing is more likely to occur during freezing and storage Denaturation, fat oxidation, color, and flavor deterioration; 2. The formed ice crystals are large in size, and the pressure causes the cell wall to rupture, and the nutrient loss is serious after thawing; 3. The freezing temperature and time are not well controlled, causing the vitreous body to freeze and make the eyes white , which seriously affects the appearance quality

Embodiment

[0024] (1) Cleaning and sterilization: immerse the fresh large yellow croaker in 5 times its volume of ozone water (concentration not less than 0.5mg / L) and wash it for 5-10 minutes. kills most of the bacteria carried on the surface of the fish;

[0025] (2) Rinse: put the cleaned and sterilized large yellow croaker in sterilized and cooled pure water for 2-3 minutes, and control the water temperature at 0-4°C to remove part of the cleaning solution remaining on the surface of the fish and achieve the purpose of pre-cooling at the same time ;

[0026] (3) Drain: Put the rinsed large yellow croaker into a plastic sieve with a mesh hole of 2-5mm in diameter, put the plastic sieve in a refrigerator at 0-4°C, let it stand for 3-5 minutes, and drain water on the surface of the fish;

[0027] (4) Packing: Put the drained large yellow croaker head upwards into a polyethylene vacuum bag with a length of 40-60 cm, a width of 10-15 cm, and a thickness of 0.18-0.25 mm. Use a vacuum pac...

Abstract

The invention discloses a pseudosciaena crocea rapid-freezing preservation process in which liquid alcohol is used as a refrigerant. A complete set of pseudosciaena crocea rapid-freezing preservation process is formed through the following steps of: washing, sterilizing, rinsing, leachating, packaging, locating, rapid freezing, rinsing, leachating, slow freezing and the like. The rapid-freezing preservation process is small in ice crystal formed on pseudosciaena crocea and capable of well keeping the quality of the pseudosciaena crocea, effectively preventing the eyes of the pseudosciaena crocea from whitening and keeping favorable appearance quality of the pseudosciaena crocea.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping, in particular to a quick-freezing and fresh-keeping process of large yellow croaker. Background technique [0002] Large yellow croaker is the main economic fish in China's coastal waters, and it is one of the traditional "four seafood" (large yellow croaker, small yellow croaker, hairtail, and squid). The meat is tender and delicious, high in protein, low in cholesterol, high in nutritional value and economic value, and is favored by consumers at home and abroad. [0003] In recent years, seawater cage culture has developed rapidly, and the production of farmed large yellow croaker is increasing, and the contradiction between production and marketing has become increasingly prominent, which has become the main factor restricting the development of large yellow croaker industry. [0004] The current large yellow croaker is mainly sold fresh, and the processed products are mainly frozen pro...
