Abstract

The invention provides a shrimp preservative and a using method of the shrimp preservative. The shrimp preservative comprises the following components in parts by weight: 2-5 parts of edible salt, 0.1-0.5 part of potassium sorbate, 0.5-1 part of vitamin C, 0.5-1 part of epigallocatechin, 0.5-1 part of tetrasodium pyrophosphate and 0.1-0.5 part of glutamic acid. Another shrimp preservative comprises the following components in parts by weight: 2-5 parts of edible salt, 0.1-0.5 part of potassium sorbate, 0.05-0.5 part of sodium tripolyphosphate, 0.05-0.1 part of sodium pyrophosphate, 0.5-1 part of epigallocatechin, 0.5-1 part of tetrasodium pyrophosphate and 0.1-0.5 part of glutamic acid. The using method for the shrimp preservative provided by the invention comprises the steps of mixing the preservative and broken ice to make preservative ice; putting fresh shrimps into the preservative ice for refrigeration under 0-4 DEG C. Compared with the prior art, the shrimp preservative has the advantages that the storage period is prolonged from 8 days of single use of the broken ice to 17 days; the preservative effect is good, and the shrimps can not discolor or go bad; furthermore, the preservative provided by the invention is also suitable for other sea food.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a fresh-keeping agent and a using method thereof. Background technique [0002] Shrimp contains a large amount of vitamin B12, is rich in zinc, iodine and selenium, and is low in calories and fat, and is favored by consumers. However, due to its concentrated harvest period, high moisture content, high bacterial carrying capacity, strong autolysis and other reasons, it is very easy to spoil and deteriorate, so keeping fresh after fishing and transportation is always a problem. [0003] After the shrimp dies, the body undergoes anaerobic degradation under the action of enzymes. When the glycogen and ATP are reduced to a certain extent, the shrimp body begins to harden. After the meat is finished, the muscles gradually soften and loosen their stiffness. At this time, the decomposition of microorganisms in the shrimp body gradually intensifies, and the components...
