Embodiment 1

[0027] Embodiment 1, a kind of preparation method of wheat protein peptide

[0028] The preparation method of described wheat protein peptide comprises the following steps:

[0029] S1 Take lactic acid and citric acid, the mass ratio of lactic acid and citric acid is 1:6, add water 10 times the total mass of lactic acid and citric acid, stir evenly to obtain a mixed solution;

[0030] S2 pulverizes wheat gluten powder, crosses 80 mesh sieves, gets wheat gluten micropowder, adds wheat gluten micropowder in step S1 gained mixture, makes the mass concentration of wheat gluten micropowder be 8%, stirs evenly, adds protection The protective agent is composed of vitamin C and D-sodium erythorbate in a mass ratio of 10:4, the amount of the protective agent added is 0.1% of the quality of the mixed solution obtained from S1, and the mixture is evenly stirred to obtain a mixed material;

[0031] S3 Place the mixed material obtained in step S2 in the irradiation reactor, seal it, and c...

Embodiment 2

[0034] Embodiment 2, a kind of preparation method of wheat protein peptide

[0035] The preparation method of described wheat protein peptide comprises the following steps:

[0036] S1 Take lactic acid and citric acid, the mass ratio of lactic acid and citric acid is 2:4, add water 15 times the total mass of lactic acid and citric acid, stir evenly to obtain a mixed solution;

[0037] S2 pulverizes the wheat gluten powder and crosses a 120 mesh sieve to obtain the wheat gluten micropowder. The wheat gluten micropowder is added to the mixed solution obtained in step S1 so that the mass concentration of the wheat gluten micropowder is 12%. Stir evenly and add protection. The protective agent is composed of vitamin C and D-sodium erythorbate in a mass ratio of 12:1, the amount of the protective agent added is 0.4% of the quality of the mixed solution obtained from S1, and the mixture is evenly stirred to obtain a mixed material;

[0038] S3 Place the mixed material obtained in s...

Embodiment 3

[0041] Embodiment 3, a kind of preparation method of wheat protein peptide

[0042] The preparation method of described wheat protein peptide comprises the following steps:

[0043] S1 Take lactic acid and citric acid, the mass ratio of lactic acid and citric acid is 1:5, add water 13 times the total mass of lactic acid and citric acid, stir evenly, to obtain a mixed solution;

[0044] S2 pulverizes the wheat gluten powder and crosses a 110 mesh sieve to obtain the wheat gluten micropowder. The wheat gluten micropowder is added to the mixed solution obtained in step S1 so that the mass concentration of the wheat gluten micropowder is 9%. Stir evenly and add protection. The protective agent is composed of vitamin C and D-sodium erythorbate in a mass ratio of 10:3, the amount of the protective agent added is 0.2% of the quality of the mixed solution obtained in step S1, and the mixture is uniformly stirred to obtain a mixed material;

[0045] S3 Place the mixed material obtaine...

Abstract

The invention belongs to the technical field of wheat protein peptide preparation, and in particular relates to a preparation method of wheat protein peptide. The preparation method of the wheat protein peptide of the present invention comprises taking lactic acid and citric acid, adding water to obtain a mixed liquid; pulverizing wheat gluten powder, sieving, adding wheat gluten fine powder into the mixed liquid, adding a protective agent to obtain a mixed material Carrying out irradiation treatment on the mixed material, filtering to obtain a sediment; freezing the sediment, thawing, drying the thawed sediment in the shade, grinding into a fine powder, sieving to obtain a fine powder; adding water to the fine powder, Adjust pH, heat up, add mixed enzyme three times, enzymatically hydrolyze, inactivate enzyme, cool to 25°C to obtain enzymolyzate, filter enzymolyzate, concentrate and dry the filtrate to obtain finished wheat protein peptide. The molecular weight distribution of the wheat protein peptide prepared by the method of the invention is narrow and the molecular weight is low. The method of the invention will not destroy the active groups on the molecular chain of the wheat protein, which is beneficial to the maintenance of the physiological activity of the wheat protein peptide.

Description

technical field [0001] The invention belongs to the technical field of wheat protein peptide preparation, and in particular relates to a preparation method of wheat protein peptide. Background technique [0002] As people have higher and higher requirements for the quality of life and pay more attention to dietary nutrition and health, active molecular peptides have become a hot spot in contemporary food and nutrition research. Active peptides as a functional factor have extremely broad development and application prospects. . Wheat is an important food crop in my country. Wheat is cultivated all over the country. The proportion of wheat in the total grain output value of the country is second only to rice and corn, ranking third, and its output and export volume are among the top in the world. Among the numerous cereal crops, the protein content in wheat is very rich, accounting for about 13% of the total mass of wheat, which is higher than that of other grains. Therefore...
