Problems solved by technology

[0005] The Chinese invention patent of CN 101343194 B discloses a production method of low-salt compound amino acid powder. The inventive method uses the extraction method to desalt the mother liquor after producing L-cystine, and then produces the amino acid with the desalted mother liquor, which has the advantages of recycling, The advantage of economy and environmental protection, but this invention method uses organic tertiary amine compound, ammonia water as extraction agent, and its compound amino acid finished product contains ammonium chloride, has potential toxicity hazard, and the source of obtaining the compound amino acid of this invention method is the production of L -The mother liquor after cystine, so it can obtain less kinds of amino acids

Embodiment 1

[0017] Grass carp amino acid nutrition powder, its preparation method comprises the following steps:

[0018] 1) Fresh grass carp meat is steamed, dried and crushed, passed through a 150-mesh sieve to obtain grass carp meat superfine powder, and the grass carp meat superfine powder is placed in supercritical CO 2 In the extraction kettle, at an extraction temperature of 48°C and an extraction pressure of 28MPa, CO 2 When the flow rate is 21L / h, extract for 2.5 hours. After the extraction, the meal is taken out from the kettle. After crushing, sieving, and drying, the grass carp protein defatted powder can be obtained. During the extraction process, fish oil can be recovered to realize the complete comprehensive utilization of grass carp and improve the The scientific and technological content of the industry increases economic benefits;

[0019] 2) Mix grass carp protein defatted powder and distilled water at a weight ratio of 1:1 to form a fish protein homogenate, add 3500U / ...

Embodiment 2

[0023] The preparation method of grass carp amino acid nutrition powder includes: degreasing, preliminary enzymolysis, reenzymolysis, and powdering, specifically including the following steps:

[0024] 1) Degreasing: Fresh grass carp meat is steamed, dried and crushed, passed through a 200-mesh sieve to obtain superfine grass carp meat powder, and placed in supercritical CO 2 In the extraction kettle, at an extraction temperature of 52°C and an extraction pressure of 32MPa, CO 2 When the flow rate is 24L / h, the extraction is carried out for 3 hours. After the extraction, the meal is taken out from the kettle. After crushing, sieving, and drying, the grass carp protein defatted powder can be obtained. The fish oil can be recovered during the extraction process to realize the complete comprehensive utilization of grass carp and improve The scientific and technological content of the industry increases economic benefits;

[0025] 2) Preliminary enzymolysis: mix grass carp protei...

Embodiment 3

[0029] Grass carp amino acid nutrition powder has a complete range of amino acids in amino acid nutrition powder, with the highest content of glutamic acid and glycine, which are the main umami amino acids; the content of amino acids such as proline, aspartic acid and alanine is also relatively high. High, their existence makes the nutritional powder present a round, soft and delicious taste. If calculated based on the crude protein in the nutritional powder, the total amount of amino acids in every 100g of crude protein is more than 80%, of which the free amino acid is more than 50%. The preparation method includes: Degreasing, preliminary enzymatic hydrolysis, re-enzymatic hydrolysis, and powdering, specifically include the following steps:

[0030] Degreasing: Fresh grass carp meat is steamed, dried and pulverized, passed through a 180-mesh sieve to obtain grass carp superfine powder, and the grass carp superfine powder is placed in supercritical CO 2 In the extraction kett...

Abstract

The invention discloses a grass carp amino acid nutrient powder. Amino acid varieties in the amino acid nutrient powder are complete; the contents of glutamic acid and glycine are the highest; the contents of amino acids such as proline, aspartic acid and alanine are high; and in crude proteins in the nutrient powder, the total amount of amino acids in each 100g of the crude proteins reaches 80% or above, wherein the amount of free amino acids is up to 50% or above. The nutrient powder has the beneficial effects that fish proteins are further hydrolyzed into micromolecular substances such as short proteins, small peptides and amino acids through microwave assist so as to improve the content of nutrient substances; and step-by-step hydrolysis degrades the bitter polypeptides so as to reducethe generation of bitter and astringency, and the match usage of several enzymes with different action modes can produce synergistic promotion effects and improve flavor so as to obtain a product with good quality.

Description

technical field [0001] The invention belongs to the field of amino acid nutrition powder, in particular to a grass carp amino acid nutrition powder. technical background [0002] Amino acid is a general term for a class of organic compounds containing amino and carboxyl groups, and is the basic unit of biological functional macromolecular proteins. In a broad sense, it refers to an organic compound containing a basic amino group and an acidic carboxyl group, but a general amino acid refers to the structural unit that constitutes a protein. Amino acids are the basic substances that make up the protein needed for animal nutrition. It is an organic compound containing a basic amino group and an acidic carboxyl group. Amino groups are linked to α-carbons as α-amino acids, and most of the amino acids that make up proteins are α-amino acids. Amino acids can play the following roles through metabolism in the human body: ①synthesis of tissue protein; ②transform into acid, hormone...
