Embodiment 1

[0009] A fresh-keeping agent for swimming crabs three wart % glycerol, 0.05~0.5% hydrogen dioxide, 0.1~0.5% isothiazolinone, 3~8% succinic acid and the balance of sterile water; b preservative is composed of the following components and contents: 0.01~0.1 % nabumetone, 0.1~1% dihydromyricetin and the remaining amount of sterile water; it can inhibit the survival of various bacteria and microorganisms, has good bactericidal and bacteriostatic effect, and inhibits the rapid autolysis of the hepatopancreas and muscles of dead individuals , among which nabumetone and dihydromyricetin promote the inhibition of cathepsin activity, succinic acid and hydrogen dioxide can promote sensory effects, and have the advantages of long-lasting action time and strong practicability. The above experimental data are nonlinear Movement, preferably, a preservative is composed of the following components and contents: 0.13% chitosan, 0.7% tea polyphenols, 2% glycerol, 0.09% hydrogen dioxide, 0.1% is...

Embodiment 2

[0011] A fresh-keeping agent for swimming crabs three wart Polyphenol, 2% glycerol, 0.09% hydrogen dioxide, 0.1% isothiazolinone, 3.5% succinic acid and the balance of sterile water; preferably, b preservative is composed of the following components and contents: 0.01% naphthalene Methone, 0.1% dihydromyricetin, 0.01~0.1% peptide aldehyde and the balance of sterile water; has unexpected effects, in addition to inhibiting the survival of various bacteria and microorganisms, it has good bactericidal and bacteriostatic effects, and can also Inhibit the rapid autolysis of the hepatopancreas and muscles of dead individuals. Among them, nabumetone and dihydromyricetin promote the effect of inhibiting cathepsin activity, and succinic acid and hydrogen dioxide can promote sensory effects. At the same time, they have a long-lasting effect and are practical The advantages of strong sex; soak the swimming crab in b preservative for 2.5h, take out and drain, and then spray the a preservat...

Abstract

The invention provides a freshness preserving agent for portunus trituberculatus. The freshness preserving agent for the portunus trituberculatus is characterized by being composed of a freshness preserving agent a and a freshness preserving agent b; the freshness preserving agent a comprises the following components in the following percentage: 0.1-2% of chitosan, 0.1-1% of tea polyphenols, 1-3% of glycerine, 0.05-0.5% of hydrogen peroxide, 0.1-0.5% of isothiazolinones, 3-8% of butanedioic acid, and the balance sterilized water; and the freshness preserving agent b comprises the following components in the following percentage: 0.01-0.1% of nabumetone, 0.1-1% of dihydromyricetin, 0.01-0.1% of peptide aldehyde, and the balance sterilized water. The freshness preserving agent for the portunus trituberculatus is capable of inhibiting existence of multiple bacteria and micro-organisms. Thus, the freshness preserving agent for the portunus trituberculatus has the following advantages: the freshness preserving agent for the portunus trituberculatus has good microbicidal and bacteriostatic effects, and is capable of inhibiting rapid autolysis of the liver, the pancreas and the muscles of dead individuals so as to promote improvements of the sensory effects; moreover, the freshness preserving agent for the portunus trituberculatus is long in effect duration and high in practicability.

Description

technical field [0001] The invention relates to a fresh-keeping agent, in particular to a fresh-keeping agent for Portunus three warts and its application. [0002] technical background [0003] The swimming crab three warts, referred to as the swimming crab, is an important marine economic crab in my country. Because of its unique flavor and rich nutritional value, it is very popular among consumers and has a large market demand. Significantly different, the swimming crabs are easy to die after leaving the water. The dead swimming crabs not only have poor flavor and taste, but also cause the histamine and other harmful substances in the crabs due to the rapid autolysis of the hepatopancreas and muscles of the dead individuals. The increase of substance content seriously affects the nutritional value and food safety of Portunus trituratus. For example, the Chinese invention patent with the prior art authorization announcement number: CN103734274B, the invention discloses a nov...
