The invention provides a low-temperature quick micro-freezing preservation technology of utensils. The low-temperature quick micro-freezing preservation 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 utensils frozen for preservation, an innovative freezing curve is applied, and the utensils are directly frozen in the micro-freezing fluid for preservation. According to kinds and sizes of materials, freezing preservation of the utensils is completed in 6-15 minutes or 15-30 minutes, which is presented in the respects that cell membranes of the utensils after the freezing preservation are not frosted to be cracked and are under an organism micro-freezing condition; and then refrigerating is performed so as to maintain the utensils after the freezing preservation fresh in quality. The low-temperature quick micro-freezing technology is an innovative micro-freezing preservation technology in the world, the cells of the utensils are kept not cracked, and thetransformation of polysaccharides substances in the utensils is improved; and when freezing preservation is performed on the fresh utensils in the shortest time according to the freezing curve, afterthe fresh utensils are stored under the refrigerating condition for 10 years or more, the fresh quality of the fresh utensils is still maintained.
