Problems solved by technology

Traditional consumption of sturgeon skin, meat, and bones has a low absorption and utilization rate by the human body. During repeated steaming, boiling, and other processing processes, a large amount of nutrients and active ingredients are lost, and it also increases the burden on the body.
The use of deep processing of sturgeon meat and bone to develop the health function food market is still rare, and there are few studies on the enzymatic hydrolysis and fermentation of sturgeon head, tail and skin

preparation example Construction

[0028] The invention provides a preparation method of sturgeon freeze-dried powder, comprising:

[0029] (1) mixing the sturgeon meat slurry with the fish cartilage slurry to obtain the sturgeon meat cartilage slurry, enzymolyzing the sturgeon meat cartilage slurry, inactivating the enzyme, and filtering to obtain the sturgeon enzymatic hydrolysis filtrate;

[0030] The enzymatic hydrolysis method comprises: enzymolyzing the sturgeon meat cartilage slurry sequentially with Bacillus subtilisin neutral protease and papain;

[0031] (2) Mixing the sturgeon skin slurry, the sturgeon head slurry and the sturgeon tail slurry to obtain the sturgeon skin head and tail slurry, mixing the sturgeon skin head and tail slurry with a nitrogen source and a carbon source, and fermenting, Obtain the sturgeon fermentation liquid, filter the sturgeon fermentation liquid to obtain the sturgeon fermentation filtrate;

[0032] The microorganisms used in the fermentation include Streptococcus therm...

Embodiment 1

[0058] (1) Cut 80kg of sturgeon meat into blocks, pulverize, add 10kg of water and grind to obtain a sturgeon meat slurry, pulverize 4kg of sturgeon cartilage, add 2kg of water and grind to obtain a sturgeon cartilage slurry, mix the sturgeon meat slurry with fish Mix the cartilage slurry, add 30 kg of water to obtain a sturgeon cartilage slurry with a fineness of 3 μm, add Bacillus subtilisin neutral protease with a quality of 4‰ of the sturgeon cartilage slurry, and enzymolyze it for 3 hours at a pH value of 7 and a temperature of 55°C. Then add papain with a quality of 2.5‰ of sturgeon meat cartilage slurry, enzymolyze it for 3 hours at a pH value of 7 and a temperature of 50°C, inactivate the enzyme at a temperature of 93°C for 20 minutes, and pass through a 100-mesh sieve to obtain sturgeon Enzyme filtrate.

[0059] (2) Grind 2kg of sturgeon skin, add 1kg of water and grind to obtain a sturgeon skin slurry, pulverize 8kg of sturgeon head, add 4kg of water and grind to obt...

Embodiment 2

[0066] (1) Cut 70kg of sturgeon meat into blocks, pulverize it, add 9kg of water and grind it finely to obtain a sturgeon meat slurry, pulverize 3 kg of sturgeon cartilage, add 1 kg of water and grind it finely to obtain a sturgeon cartilage slurry, mix the sturgeon meat slurry with fish Mix the cartilage slurry, add 25 kg of water to obtain a sturgeon cartilage slurry with a fineness of 5 μm, add Bacillus subtilisin neutral protease with a quality of 2‰ of the sturgeon cartilage slurry, and enzymolyze it for 4 hours at a pH value of 6 and a temperature of 45°C. Then add papain of 1.5‰ of sturgeon meat cartilage slurry, enzymatically hydrolyze for 4 hours under the conditions of pH value 6 and temperature 45°C, inactivate the enzyme at 90°C for 30 minutes, and pass through an 80-mesh sieve to obtain sturgeon enzyme solution filtrate.

Abstract

The invention provides a preparation method of sturgeon freeze-dried powder and the sturgeon freeze-dried powder, and belongs to the technical field of food processing. The preparation method comprises the steps that sturgeon meat cartilage slurry is subjected to enzymolysis, enzyme deactivation and filtering, and sturgeon enzymolysis filtrate is obtained; sturgeon skin head and tail slurry is mixed with a nitrogen source and a carbon source, and fermenting is performed to obtain sturgeon fermentation filtrate; and the sturgeon enzymolysis filtrate is mixed with the sturgeon fermentation filtrate, and vacuum freeze-drying is performed to obtain the sturgeon freeze-dried powder. The sturgeon freeze-dried powder obtained by enzymolysis and probiotic fermentation not only has no fishy smell,but also has a unique fermentation flavor and entire nutritional ingredients, and the sturgeon freeze-dried powder is small in average molecular weight, strong in activity, high in bioavailability andeasier to absorb for a human body.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of sturgeon freeze-dried powder and sturgeon freeze-dried powder. Background technique [0002] Sturgeon is a large and medium-sized characteristic freshwater fish with high economic value. At present, my country's sturgeon breeding volume has reached 85% of the world's total sturgeon breeding, and it has become the world's largest sturgeon breeding country. Sturgeon is full of treasures and is called a living fossil in water. [0003] At present, most of the products supplied to the market are fresh products. On the other hand, product development mainly includes quick-frozen prepared products, which are re-cooked products; ready-to-eat snack foods in bags, such as high-grade seed sauce, grilled fish fillets, etc.; by-product fish meat, Fish skin, fish bones, etc., the processing utilization rate is low. And the sturgeon has an earthy s...
