Embodiment 1
[0028] (1) Cleaning: After washing the Chinese tube whip shrimp, dry it with cold air until the surface is dry;
[0029] (2) Soaking: Soak the Chinese tube whip shrimp in the freezing treatment agent at a temperature of 5°C for at least 10 minutes, then drain. The mass ratio of the Chinese tube whip shrimp and the freezing treatment agent is 1:5, and the freezing treatment agent consists of Component composition in mass percent: 5% glycerin, 1% carnosol, 0.01% transglutaminase, 1% cysteine, 0.5% betaine, 0.1% arbutin, 0.1% flavanone Alcohol, 0.1% cuminic acid, 0.5% konjac mannan, the balance is water;
[0030] (3) Deep freezing and quick freezing: pre-cool the Chinese tube whip shrimp in step (2) until the central temperature of the Chinese tube whip shrimp is 5°C, and then place it in a liquid nitrogen quick freezing cabinet for deep freezing and quick freezing, the process steps of deep freezing and quick freezing It is as follows: first reduce the ambient temperature in th...
Embodiment 2
[0033] (1) Cleaning: After washing the Chinese tube whip shrimp, dry it with cold air until the surface is dry;
[0034] (2) Soaking: soak the Chinese tube whip shrimp in the freezing treatment agent at a temperature of 10°C for at least 10 minutes, and then drain. The mass ratio of the tube whip shrimp and the freezing treatment agent is 1:10, and the freezing treatment agent consists of Component composition in mass percent: 10% glycerin, 3% carnosol, 0.03% transglutaminase, 3% cysteine, 1% betaine, 0.3% arbutin, 0.3% flavanone Alcohol, 0.3% cuminic acid, 1% konjac mannan, the balance is water;
[0035] (3) Deep freezing and quick freezing: pre-cool the Chinese tube whip shrimp in step (2) until the central temperature of the Chinese tube whip shrimp is 15°C, and then place it in a liquid nitrogen quick freezing cabinet for deep freezing and quick freezing, the process steps of deep freezing and quick freezing It is: first reduce the ambient temperature in the liquid nitrog...
Embodiment 3
[0038] (1) Cleaning: After washing the Chinese tube whip shrimp, dry it with cold air until the surface is dry;
[0039] (2) Soaking: Soak the Chinese tube whip shrimp in the freezing treatment agent at a temperature of 7°C for at least 10 minutes, then drain. The mass ratio of the Chinese tube whip shrimp and the freezing treatment agent is 1:7, and the freezing treatment agent consists of Component composition in mass percent: 7% glycerin, 2% carnosol, 0.02% transglutaminase, 2% cysteine, 0.7% betaine, 0.2% arbutin, 0.2% flavanone Alcohol, 0.2% cuminic acid, 0.6% konjac mannan, the balance is water;
[0040] (3) Deep freezing and quick freezing: pre-cool the Chinese tube whip shrimp in step (2) until the central temperature of the Chinese tube whip shrimp is 10°C, and then place it in a liquid nitrogen quick freezing cabinet for deep freezing and quick freezing, the process steps of deep freezing and quick freezing It is: first reduce the ambient temperature in the liquid n...
