Problems solved by technology

The protective agent composition used for cryopreservation and quick-freezing of monodon shrimp cannot inhibit the activity of phenoloxidase in the shrimp body, and will cause melanin precipitation on the shell of the shrimp, that is, the formation of black spots (blackening), serious It affects the appearance and also restricts the commercial value of the shrimp. In addition, the protective agent composition cannot maintain the original characteristic color of the shrimp. After thawing, the outer color of the shrimp will be dull, and the shrimp head will fall off from the shrimp body.

Embodiment 1

[0022] After washing and draining the Chinese tube whip shrimp, soak it in the Chinese tube whip shrimp cryogenic quick-freezing treatment agent at a temperature of 5°C for at least 10 minutes, drain it, and perform liquid nitrogen cryogenic quick-freezing. The Chinese tube whip shrimp and The mass ratio of the freezing treatment agent is 1:5, wherein the deep-freezing and quick-freezing treatment agent for Chinese whip shrimp is composed of the following components in mass percentage: 5% glycerin, 1% carnosol, 0.01% transglutaminase , 1% cysteine, 0.5% betaine, 0.1% arbutin, 0.1% flavanols, 0.1% cuminic acid, 0.5% konjac mannan, the balance is water, cryogenically frozen in liquid nitrogen The process steps are: first reduce the ambient temperature in the liquid nitrogen cabinet to -30°C within 3 minutes, then drop to -65°C within 4 minutes, and finally drop to -90°C within 3 minutes, and maintain the environment at -90°C The temperature continues to quick-freeze the Chinese ...

Embodiment 2

[0024] After washing and draining the Chinese tube whip shrimp, soak it in the Chinese tube whip shrimp cryogenic quick-freezing treatment agent at a temperature of 10°C for at least 10 minutes, drain it, and carry out liquid nitrogen cryogenic quick-freezing. The Chinese tube whip shrimp and The mass ratio of the freezing treatment agent is 1:10, wherein the cryopreservation and quick-freezing treatment agent for Chinese whip shrimp consists of the following components by mass percentage: 10% glycerol, 3% carnosol, 0.03% transglutaminase , 3% cysteine, 1% betaine, 0.3% arbutin, 0.3% flavanols, 0.3% cuminic acid, 1% konjac mannan, the balance is water, cryogenically frozen in liquid nitrogen The process steps are: first reduce the ambient temperature in the liquid nitrogen cabinet to -20°C within 3 minutes, then drop to -60°C within 4 minutes, and finally continue to drop to -80°C within 3 minutes, and maintain the environment at -80°C The temperature continues to quick-freeze...

Embodiment 3

[0026]After washing and draining the Chinese tube whip shrimp, soak it in the Chinese tube whip shrimp cryogenic quick-freezing treatment agent at a temperature of 7°C for at least 10 minutes, drain it, and carry out liquid nitrogen cryogenic quick-freezing. The Chinese tube whip shrimp and The mass ratio of the freezing treatment agent is 1:7, wherein the deep-freezing quick-freezing treatment agent for Chinese whip shrimp consists of the following components by mass percentage: 7% glycerol, 2% carnosol, 0.02% transglutaminase , 2% cysteine, 0.7% betaine, 0.2% arbutin, 0.2% flavanols, 0.2% cuminic acid, 0.7% konjac mannan, the balance is water, cryogenically frozen in liquid nitrogen The process steps are: first reduce the ambient temperature in the liquid nitrogen cabinet to -25°C within 3 minutes, then drop to -63°C within 4 minutes, and finally continue to drop to -85°C within 3 minutes, and maintain the environment at -85°C The temperature continues to quick-freeze the Ch...

Abstract

The invention discloses a deeply-cold quick-frozen treatment agent for solenocera crassicornis. The deeply-cold quick-frozen treatment agent is prepared from the following components in percentage by mass: 5-10% of glycerine, 1-3% of carnosol, 0.01-0.03% of transglutaminase, 1-3% of cysteine, 0.5-1% of betaine, 0.1-0.3% of arbutin, 0.1-0.3% of dihydroflavonol, 0.1-0.3% of cuminic acid, 0.5-1% of konjac glucomannan and the balance of water. The deeply-cold quick-frozen treatment agent for solenocera crassicornis is reasonable and scientific in formula, is good in fresh-keeping and color-protection effect, can prevent the situation that solenocera crassicornis heads come off from solenocera crassicornis bodies, and can effectively restrain nigrities. The invention further discloses an application of the deeply-cold quick-frozen treatment agent for solenocera crassicornis in deeply-cold quick-frozen solenocera crassicornis. The solenocera crassicornis is soaked in the deeply-cold quick-frozen treatment agent for at least 10min, then draining is performed, and liquid nitrogen deeply-cold quick-frozen treatment is performed, so that the method is simple in steps and high in maneuverability.

Description

technical field [0001] The invention relates to an additive, in particular to a cryogenic and quick-freezing treatment agent for Chinese tube whip shrimp and its application. Background technique [0002] Chinese tube whip shrimp [Solenocera crassicornis (H.Milne-Edwards)], belongs to Arthropoda (Arthropoda), Crustacea (Crustacea), soft armor subclass (Malacostraca), decapod (Decapoda), swimming suborder (Natanita ), the family Solenoceridae, and the genus Solenocera. Its common name is also called red shrimp, an annual crustacean, similar in appearance to Penaeus sinensis and Penaeus vannamei, the longest adult can reach 15cm, it is red, the shell is thin and smooth, and the first 6 abdominal segments are darker in color and red band-shaped , There are no fixed spines on the side of the telson. Compared with the shrimps caught in other coastal areas, this shrimp has its unique advantages. It is mainly distributed in the offshore areas near the coast of Zhejiang, and inhab...
