Low-temperature quick micro-freezing fresh-keeping technology for ocean-going fishing aquatic products

Abstract

The invention provides a low-temperature quick micro-freezing fresh-keeping technology of ocean-going fishing aquatic products. The low-temperature quick micro-freezing fresh-keeping technology adoptsa high-tech biological technology, the ice crystal condition of organism cells under a low-temperature condition is studied, a low temperature and ultra-low temperature technology and a newly-invented micro-freezing fluid from natural components is applied to the ocean-going fishing aquatic products frozen for fresh keeping, an innovative freezing curve is applied, and the ocean-going fishing aquatic products are directly frozen in the micro-freezing fluid for fresh keeping. According to kinds and sizes of materials, freezing fresh keeping of the ocean-going fishing aquatic products is completed in 6-15 minutes or 15-30 minutes, which is presented in the respects that cell membranes of the ocean-going fishing aquatic products after the freezing fresh keeping are not frosted to be crackedand are under an organism micro-freezing condition; and then refrigerating is performed so as to maintain the ocean-going fishing aquatic products after the freezing fresh keeping fresh in quality. The low-temperature quick micro-freezing technology is an innovative micro-freezing fresh-keeping technology in the world, the cells of the ocean-going fishing aquatic products are kept not cracked, andthe transformation of polysaccharides substances in the ocean-going fishing aquatic products is improved; and when freezing fresh-keeping is performed on the fresh ocean-going fishing aquatic products in the shortest time according to the freezing curve, after the fresh ocean-going fishing aquatic products are stored under the refrigerating condition for within 12 months, the fresh quality of thefresh ocean-going fishing aquatic products is still maintained.

Description

1. Technical field [0001] The invention relates to the technical field of low-temperature preservation of deep-sea fishing aquatic products, and proposes a low-temperature, rapid micro-freezing and fresh-keeping technology of deep-sea fishing aquatic products. 2. Background technology [0002] We have found that in nature, the somatic cells of hibernating animals have a natural antifreeze mechanism, such as frogs, loach, crucian carp, and other animals and aquatic animals that live in subtropical and frigid regions. The polysaccharide antifreeze substances of somatic cells have a sharp increase in the number of double bonds of fatty acid molecules in their subcellular membranes. The antifreeze is studied from the perspective of cell dynamics, so that the somatic cells are not frozen due to the drop in external temperature. Crystal frost heaves and ruptures; organisms preserve their living bodies by keeping their body cells in a slightly frozen state, and recover and revive w...

AI Technical Summary

Problems solved by technology

In the process of freezing and refrigerated industrialized production of distant-sea fishing aquatic products, when the temperature of the freezing equipment drops, ice crystals are first produced between the cells of distant-sea fishing aquatic products, and as the temperature gradually decreases, ice crystals are produced in the cells, so that It leads to the imbalance of pressure inside and outside the cell, thus destroying the protoplasm and cell membrane, leading to cell lysis and death
