Embodiment 1

[0031] A kind of sea shrimp nutrient extraction method that the present invention proposes, comprises the following steps:

[0032] (1) Soak the sea prawns, remove the salt on the surface, and wash the heads and shells of the sea prawns.

[0033] (2) The sea shrimp is dried with hot air, and the drying temperature of the hot air is 85°C.

[0034] (3) Crushed after drying and sieved.

[0035] (4) The pretreated sea shrimp is enzymolyzed with protease in the water system. The mass ratio of protease to sea shrimp is 1000U per gram of sea shrimp. After the reaction, the enzyme activity is inactivated to obtain the enzymatic hydrolysis solution.

[0036] (5) Add the material to water or a solvent with a weight ratio of ethanol and water of 1:1. The amount of solvent is 1 times the weight of the broken sea shrimp. Add acid to adjust the pH value of the solvent to 4. The water used is distilled water or drinking water. water.

[0037] (6) Add papain:alkaline protease:flavor protea...

Embodiment 2

[0047] A kind of sea shrimp nutrient extraction method that the present invention proposes, comprises the following steps:

[0048] (1) Soak the sea prawns, remove the salt on the surface, and wash the heads and shells of the sea prawns.

[0049] (2) The sea shrimp is dried with hot air, and the drying temperature of the hot air is 85°C.

[0050] (3) Crushed after drying and sieved.

[0051] (4) The pretreated sea prawns are enzymatically hydrolyzed with protease in the water system. The mass ratio of protease to sea prawns is 2000U per gram of sea prawns.

[0052] (5) Add the material to water or a solvent with a weight ratio of ethanol and water of 1:1. The amount of solvent is twice the weight of the broken sea shrimp, and acid is added to adjust the pH value of the solvent to 5. The water used is distilled water or drinking water. water.

[0053] (6) Add papain:alkaline protease:flavor protease=2.0:1:1.75 to the above solution for limited enzymolysis of 0.6% compound en...

Embodiment 3

[0063] A kind of sea shrimp nutrient extraction method that the present invention proposes, comprises the following steps:

[0064] (1) Soak the sea prawns, remove the salt on the surface, and wash the heads and shells of the sea prawns.

[0065] (2) The sea shrimp is dried with hot air, and the drying temperature of the hot air is 85°C.

[0066] (3) Crushed after drying and sieved.

[0067] (4) The pretreated sea shrimp is enzymolyzed with protease in the water system. The mass ratio of protease to sea shrimp is 3000U per gram of sea shrimp. After the reaction, the enzyme activity is inactivated to obtain the enzymatic hydrolysis solution.

[0068] (5) Add the material to water or a solvent with a weight ratio of ethanol and water of 1:1. The amount of solvent is 3 times the weight of the broken sea shrimp. Add acid to adjust the pH value of the solvent to 6. The water used is distilled water or drinking water. water.

[0069] (6) Add papain: alkaline protease: flavor prot...

Abstract

The invention discloses an extraction method of prawn nutrients. The extraction method comprises the following steps: (S1) soaking the prawns to remove seawater salinity on the surfaces of the prawns,and cleaning heads and shells of the prawns; (S2) carrying out hot-air drying on the prawns; (S3) crushing after the drying, and sieving; (S4) adding the material into water or a solvent containing ethanol and water in a weight ratio of 1 to 1, and adding acid so as to adjust the pH value to 4-6, wherein the amount of the solvent is equal to 1-3 times of the weight of the crushed prawn; (S5) adding compound enzyme in the solution for limited enzymolysis, so as to obtain enzymatic hydrolysate; and (S6) adding edible-grade alcohol which is equal to 0.5%-2% of volume of the enzymatic hydrolysateinto the enzymatic hydrolysate, treating at 40-55 DEG C for 0.5-1.5 hours, so as to obtain edible-grade alcohol treatment liquid. According to the extraction method, the fishy flavor of the prawns can be effectively removed, the recovery rate of proteins is high, the nutrients in the heads and shells of the prawns can be furthest maintained, and the prawn nutrients are natural and healthy, are not added with a preservative and have stable and excellent quality.

Description

technical field [0001] The invention relates to the technical field of processing glutinous rice cooked food powder, in particular to a method for extracting sea shrimp nutrients. Background technique [0002] Shrimp is one of the main seafood in my country's coastal areas, but most of the shrimp heads and shells are thrown away as waste during processing, so the nutrients in the shrimp heads and shells cannot be used. They contain zinc, manganese, germanium More than 14 kinds of trace elements necessary for the human body, such as iron, copper, etc., 18 kinds of amino acids such as tryptophan and lysine, various vitamins such as vitamin A and vitamin E, and protein, have the medical effect of nourishing and strengthening the body. [0003] The purpose of the present invention is to provide an effective method for extracting abundant nutrients stored in sea prawns. Contents of the invention [0004] The purpose of the present invention is to solve the problem of fully extr...
