A multi-layer ice 
glazing method for frozen 
shrimp meat comprises steps as follows: 1) preparation of a first-layer ice 
glazing liquid: the 
mass concentration of NaCl is 0.04%-0.08%, the 
mass concentration of 
sodium alginate 
oligosaccharide is 0.5%-1.0%, and the 
mass concentration of 
lactitol is 0.4%-0.8%; the temperature of the first-layer ice 
glazing solution is controlled to be in a range of 0.2-0.8 DEG C, and 
shrimp meat is completely immersed for 3-7 s and then glazed with first-layer ice 
glaze according to conventional operation; preparation of a second-layer ice glazing solution; the mass concentration of 
sodium citrate is 0.05%-0.09%, the mass concentration of k-
carrageenan is 0.01%-0.04%, the mass concentration of 
carboxymethyl cellulose is 0.05%-0.08% and the mass concentration of L-
sodium ascorbate is 0.1%-0.3%; the temperature of the second-layer ice glazing solution is controlled to be in a range of 0.6-1.2 DEG C, the 
shrimp meat with the first-layer ice 
glaze is immersed into the second-layer ice glazing solution for 5-10 s and glazed with second-layer ice 
glaze according to conventional operation. The process is simple and safe and efficient to use, ice glaze 
cracking can be effectively prevented, 
microorganism growth is controlled, the product storage time is effectively prolonged, the total weight of ice glaze is only 8%-11% of the 
wet weight of the product, and the rights of consumers are protected.
