Abstract

The present invention relates to an euphausia superba ice temperature preservation method which comprises the following steps: (1) pre-treatment; (2) preservative agent A treatment; (3) preservative agent B treatment; and (4) low temperature storage. The preservative agent A is a fluidized ice solid-liquid mixture which consists of a fluidized ice solid and aqueous solution; and wherein the mass concentration of the fluidized ice solid is 30-40%, and concentrations of each components of the aqueous solution are as follows: 6-10 g/L smoked plum extract, 8-12 g/L honeysuckle extract, 3-5 g/L citric acids, 1-2 g/L phytic acids, and 0.05-0.3 g/L magnesium salt. The preservative agent B is also a fluidized ice solid-liquid mixture, wherein the mass concentration of the fluidized ice solid is 50-80%, and concentrations of each components of the aqueous solution are as follows: 7-10 g/L smoked plum extract, 10-14 g/L honeysuckle extract, 2-3 g/L citric acids, and 0.8-1 g/L phytic acid. The ice temperature preservation method can effectively suppress the large reproduction of pathogens and spoilage organisms, effectively prevent shrimp body melanosis, and ensure shrimp meat quality and freshness.

Description

technical field [0001] The invention relates to the field of seafood preservation, in particular to an ice-temperature preservation method for Antarctic krill. Background technique [0002] Antarctic krill (Euphausia superba), also known as giant krill or Antarctic krill, is a krill that lives in the waters of Antarctica in the Southern Ocean. Antarctic krill is a shrimp-like invertebrate that lives in groups, sometimes with a density of 10,000-30,000 individuals / m 3 . They feed on tiny phytoplankton, from which they convert the energy from primary production to maintain their life cycle in the pelagic zone. They are key species in the Antarctic ecosystem. In terms of biomass, they may be the most abundant on Earth. successful animal species. Antarctic krill is the largest animal protein pool on earth. According to estimates, the biological reserves of Antarctic krill are 400-1.55 billion tons, and the annual sustainable catch is 70-200 million tons. The water content of...
