Problems solved by technology

In the industrial production process of green tea freezing and cold storage, when the temperature of the freezing equipment is lowered, ice crystals are first produced between green tea cells, and as the temperature gradually decreases, ice crystals are produced in the cells again, which leads to The pressure is not balanced, which destroys the protoplasm and cell membrane, leading to cell lysis and death

Abstract

The invention provides a low-temperature quick micro-freezing fresh-keeping technology of fresh tea leaves. The low-temperature quick micro-freezing fresh-keeping technology adopts a 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 fresh tea leaves frozen for fresh keeping, an innovative freezing curve is applied, and the fresh tea leaves are directly frozen in the micro-freezing fluid for fresh keeping. According to kinds and sizes of materials, freezing fresh keeping of the fresh tea leaves is completed in 6-15 minutes or 15-30 minutes, which is presented in the respects that cell membranes of the fresh tea leaves after the freezing fresh keeping are not frosted to be cracked and are under an organism micro-freezing condition; and then refrigerating is performed so as to maintain the fresh tea leaves 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 fresh tea leaves are kept not cracked, and the transformation of polysaccharides substances in the fresh tea leaves is improved; and when freezing fresh-keeping is performed on the fresh fresh tea leaves in the shortest time according to the freezing curve, after the fresh fresh tea leaves are stored under the refrigerating condition for within 12 months, the fresh quality of thefresh fresh tea leaves is still maintained.

Description

1. Technical field [0001] The invention relates to the technical field of low-temperature fresh-keeping of tea greens, and proposes a low-temperature rapid micro-freezing fresh-keeping technology of tea greens. 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 when the temperature rises. The evolution of organ...
