Problems solved by technology

[0004] Although Chinese scholars have done some research on chia seeds, the depth of development and utilization is far from enough. Chia seeds are only added as a compound raw material to food, feed, etc., and the added value of the product is low.
Moreover, the price of chia seeds is relatively expensive. If its efficacy cannot be fully exerted, it will hinder the introduction and sales of chia seeds in my country

Embodiment 1

[0031] A preparation method of chia seed polypeptide, the method comprising the steps of:

[0032] a. Raw material processing: remove the impurities in the chia seeds, and use a pulverizer to crush the chia seeds.

[0033] b. Raw material dissolution: Fully stir and dissolve the pulverized chia seeds and water at a ratio of 1:20. After the dissolution is complete (30 minutes), stir and raise the temperature to control the temperature of the feed liquid to 50°C.

[0034] c. Enzymolysis: under the condition of natural pH value and 50°C, add 0.5‰ of Protamex enzyme and 1.0‰ of flavor protease equivalent to the weight of the substrate to the feed solution with a substrate concentration of 5%, and stir for 4 hours to obtain Chia Seed Enzyme Hydrolyzate.

[0035] d. Enzyme inactivation: Heat the enzymatic solution to 80°C for 20 minutes at a constant temperature to achieve the effect of inactivating the enzyme.

[0036] e. Concentration: Use a double-effect concentrator to concent...

Embodiment 2

[0041] A preparation method of chia seed polypeptide, the method comprising the steps of:

[0042] a. Raw material processing: remove the impurities in the chia seeds, and use a pulverizer to crush the chia seeds.

[0043] b. Dissolution of raw materials: Fully stir and dissolve the pulverized chia seeds and water at a ratio of 1:25. After the dissolution is complete (35 minutes), stir and raise the temperature to control the temperature of the feed liquid to 50°C.

[0044] c. Enzymolysis: under the condition of natural pH value and 50°C, add 1.0‰ of Protamex enzyme and 1.5‰ of flavor protease equivalent to the weight of the substrate to the feed solution with a substrate concentration of 4%, and stir for 4 hours to obtain Chia Seed Enzyme Hydrolyzate.

[0045] d. Enzyme inactivation: Heat the enzymatic solution to 80°C for 20 minutes at a constant temperature to achieve the effect of inactivating the enzyme.

[0046] e. Concentration: Use a double-effect concentrator to conce...

Embodiment 3

[0051] A preparation method of chia seed polypeptide, the method comprising the steps of:

[0052] a. Raw material processing: remove the impurities in the chia seeds, and use a pulverizer to crush the chia seeds.

[0053] b. Dissolution of raw materials: Fully stir and dissolve the pulverized chia seeds and water at a ratio of 1:25. After the dissolution is complete (40 minutes), stir and raise the temperature to control the temperature of the feed liquid to 50°C.

[0054] c. Enzymolysis: under the condition of natural pH value and 50°C, add Protamex enzyme 1.5‰ and flavor protease 2.0‰ equivalent to the weight of the substrate to the feed solution with a substrate concentration of 5%, and stir for 4 hours to obtain Chia Seed Enzyme Hydrolyzate.

[0055] d. Enzyme inactivation: Heat the enzymatic solution to 80°C for 20 minutes at a constant temperature to achieve the effect of inactivating the enzyme.

[0056] e. Concentration: Use a double-effect concentrator to concentra...

Abstract

The invention provides a chia seed polypeptide and a preparation method thereof. The preparation method comprises the following steps of (1) crushing chia seeds; (2) dissolving; (3) performing enzymolysis; (4) concentrating and drying to obtain the chia seed polypeptide, wherein the enzymolysis manner in the step (3) is adding protamex enzyme and flavourzyme. According to the chia seed polypeptide and the preparation method thereof, the content of the prepared polypeptide is more than 70%, the prepared polypeptide is solid powder, the luster is not changed, the product is not bitter and does not have off-flavor, the prepared polypeptide is easy to dissolve, and the dissolution speed is higher than the self dissolution speed of the chia seed.

Description

technical field [0001] The invention relates to a preparation method of a polypeptide in the field of health food, in particular to a preparation method of a chia seed polypeptide. Background technique [0002] Chia seed, also known as Chia seed, is the seed of Chia (scientific name Chia sage, Salvia Hispanica L.), which belongs to Labiatae, Labiatae, and the plant originated in southern Mexico and Guatemala. Chia seeds are flat and oval, about 2mm in length and diameter, with marble-like patterns and luster, and are available in white and gray-black colors. They have been used as food for thousands of years. Chia seeds are called "superfoods" because they are rich in nutrients. According to related data, chia seeds contain about 18% essential fatty acid Omega-3, 23% protein, 37% dietary fiber, and antioxidants. The indicator ORAC is as high as 9800 units, completely free of sugar, salt and cholesterol. Chia seeds also contain many high-content trace elements, such as calci...
