preparation example Construction

[0033] The second is a method for preparing slow-digesting oat protein. The slow-digesting oat protein is prepared by high-voltage pulsed electric field treatment and pepsin-directed enzymatic hydrolysis. The specific scheme is as follows:

[0034] (1) After mixing the oat protein and oat β-glucan obtained by the above method, disperse in water, and then use high-voltage pulsed electric field to treat it;

[0035] (2) Extract part of the easily digestible protein in the solution obtained in step (1) by pepsin-directed enzymatic removal, adjust the pH, centrifuge, and finally dry the obtained precipitate to obtain slow-digestible oat protein.

Embodiment 1

[0039] A slow-digesting oat protein and a preparation method thereof. Specific steps are as follows:

[0040] (1) Crumble oat grains through a 60-mesh sieve, disperse 500 parts of oat flour in 5000 parts of deionized water, add 50 parts of lipase, stir and degrease to obtain an enzymatic hydrolysis solution.

[0041] (2) Adjust the pH of the enzymatic solution obtained in step (1) to 10, stir and extract for 4 hours, centrifuge (5000g, 15min) to remove the precipitate, adjust the pH of the supernatant to 5.5, centrifuge (12000g, 15min) to collect the precipitate, and dry it Instant oat protein.

[0042] (3) Take 2000 parts of the supernatant after extracting oat protein in step (2), and adjust its pH to 7, add 8000 parts of ethanol to it, let it stand for 4h, centrifuge (12000g, 15min) to get the precipitate, and remove it Dried to get oat β-glucan.

[0043] (4) Take 50 parts of oat protein and 5 parts of oat β-glucan obtained in the above steps and mix them uniformly and d...

Embodiment 2

[0046] A slow-digesting oat protein and a preparation method thereof. Specific steps are as follows:

[0047] (1) Crush oat grains through a 60-mesh sieve, disperse 600 parts of oat flour in 3000 parts of deionized water, add 18 parts of lipase, and stir to degrease.

[0048] (2) Adjust the pH of the enzymolysis solution obtained in step (1) to 8, stir and extract for 2 hours, centrifuge (3000g, 10min) to remove the precipitate, adjust the pH of the supernatant to 4.5, centrifuge (8000g, 10min) to collect the precipitate, and dry it Instant oat protein.

[0049] (3) Take 1500 parts of the supernatant after extracting oat protein in step (2), and adjust its pH to 7, add 3000 parts of ethanol to it, let stand for 2h, centrifuge (8000g, 10min) to get the precipitate, and Dried to get oat β-glucan.

[0050] (4) Take 100 parts of oat protein and 1 part of oat β-glucan obtained in the above steps and mix them uniformly and disperse them in 303 parts of deionized water. It is proce...

Abstract

The invention discloses a slowly digestible oat protein and a preparation method thereof, and belongs to the field of nutrition and health. The method comprises the following steps of dispersing crushed and sieved oat powder in deionized water, performing degreasing, separating out an oat protein and oat beta-glucan, mixing the obtained oat protein and oat beta-glucan, then performing dissolution, next, treating the materials by using a high-voltage pulsed electric field, removing parts of digestible protein through directional enzymolysis by pepsin, performing centrifugation after pH value regulation, and finally drying the obtained precipitates to obtain the slowly digestible oat protein. The oat protein prepared by the method can be widely applied to the fields of common foods, health care foods, formula foods with special medical purposes and the like, and a new solution is provided for foods for people groups with obesity, diabetes mellitus and the like.

Description

technical field [0001] The invention relates to a slow-digesting oat protein and a preparation method thereof, belonging to the field of nutrition and health. Background technique [0002] Protein with fast digestion and absorption has always been a hot topic in nutrition research. However, with the continuous improvement of people's living standards, the number of obese patients and fitness enthusiasts continues to increase, and research directions such as slow digestion and energy intake control are being sought. More and more attention. There have been many research reports on slow-digesting starch, but there are few reports on slow-digesting protein. [0003] Oatmeal is one of the top ten healthy foods recommended to modern people by the American "Time" special issue. It has beneficial physiological effects such as reducing "three highs" and improving immunity. The protein content of oats is higher than that of other cereal crops, and the amino acid score is high. It i...
