Preservative for euphausia superba on ocean fishing vessel, as well as preparation method and application of preservative

Abstract

The invention relates to a preservative for euphausia superba on an ocean fishing vessel. The preservative consists of the following components in parts by weight: 10 to 15 parts of bayberry extract, 12 to 18 parts of lonicera japonica extract, 5 to 10 parts of sargassum extract, 5 to 10 parts of hairtail ferrous peptide, 2 to 4 parts of an antioxidant, 1 to 3 parts of phytic acid, 1 to 3 parts of citric acid, 1 to 2 parts of sorbitol and 30 to 50 parts of distilled water. The invention also relates to a preservation method for the preservative and the application of the preservative to preservation transportation of euphausia superba. The preservative is scientific and reasonable in formula, a preparation process is simple, and each component is synergized to achieve good bacterium inhibition, preservation and blackening prevention effects; the euphausia superba treated by the preservative can be preserved for at least 30 days in a partial freezing state, so that the preservation time of the euphausia superba in the partial freezing state is greatly prolonged, an ocean transportation requirement is met, power consumption for low-temperature freezing storage in conventional ocean transportation is avoided, and the preservative can be widely popularized to ocean transportation of other marine products.

Description

technical field [0001] The invention relates to the field of fresh-keeping seafood, in particular to a fresh-keeping agent for Antarctic krill on an ocean-going fishing vessel, a preparation method and application thereof. 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 ...

In addition, krill shrimp shells contain high fluorine. After krill dies, the fluorine in the shrimp shells will slowly penetrate into the shrimp meat, resulting in a sharp increase in the fluorine content of the shrimp meat, thereby affecting its edible value. In addition, Antarctic phosphorus During the transp
