Low-temperature quick micro-freezing fresh-keeping technology for bean seeds

Abstract

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

Description

1. Technical field [0001] The invention relates to the technical field of low-temperature fresh-keeping of bean seeds, and proposes a low-temperature rapid micro-freezing fresh-keeping technology of bean seeds. 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...

Problems solved by technology

In the industrial production process of bean seed freezing and refrigeration, when the temperature of the freezing equipment is lowered, ice crystals are first produced between the bean seed cells, and as the temperature gradually decreases, ice crystals are produced in the cells, which leads to Unbalanced pressure inside and outside the cell, which destroys the protoplasm and cell membrane, leading to cell lysis and death
