Embodiment 1

[0025] A. Take 0.5kg soybean protein powder and 0.5kg whey protein powder and mix them evenly;

[0026] B. Add 20kg of water at 80°C, and stir with a high-speed mixer for 20 minutes to form a uniform suspension without agglomeration;

[0027] C. Filtrate through a 5000 Dalton filter membrane while hot at a temperature not lower than 60°C, using a pressure of 0.4-0.6 MPa to obtain about 16 liters of filtrate A;

[0028] D. Filter the filtrate A through a 500 Dalton filter membrane to separate out small molecular substances, moisture, salt, etc., and the obtained filtrate B is about 1 / 4 of the filtrate A;

[0029] E. Spray-dry the filtrate B, select the inlet air temperature as 90°C, and the eruption volume as 3-5 liters / minute;

[0030] F, add the lecithin of powder weight 1% that obtains after spray drying, mix evenly;

[0031] G, bagging or canning.

[0032] In the protein powder prepared by the method of Example 1, the molecular weight below 5000 accounts for 95%, and amo...

Embodiment 2

[0038] A. Take 0.4kg soybean protein powder and 0.8kg whey protein powder and mix them evenly;

[0039] B. Add 22kg of water at 85°C, and stir with a high-speed mixer for 40 minutes to form a uniform suspension without agglomeration;

[0040] C. Filtrate through a 5000 Dalton filter membrane while hot at a temperature not lower than 60°C, using a pressure of 0.4-0.6 MPa to obtain about 16 liters of filtrate A;

[0041] D. Filter the filtrate A through a 500 Dalton filter membrane to separate out small molecular substances, moisture, salt, etc., and the obtained filtrate B is about 1 / 4 of the filtrate A;

[0042] E. Spray-dry the filtrate B, select the inlet air temperature as 90°C, and the eruption volume as 3-5 liters / minute;

[0043] F, add lecithin about 1.2% of the powder weight obtained after spray drying, and mix evenly;

[0044] G, bagging or canning.

[0045] In the protein powder prepared according to the method in Example 2, the molecular weight below 5000 account...

Abstract

The invention discloses a production method of low-molecular-weight nutritional protein powder, which comprises the following steps: taking soy protein powder and whey protein powder as raw materials; adding water whose the temperature is 70-90 DEG C, and mixing the mixture into uniform suspension; filtering the suspension through a filtration film under the temperature no less than 60 DEG C, to be specific, firstly filtering the suspension through a 5,000-daltonian filtration film and then filtering the filtrate through a 500-daltonian filtration film; spraying and drying the obtained filtrate; adding sprayed and dried lecithin whose powder weight is 0.5-1.5%; and uniformly mixing the mixture. According to the production method of low-molecular-weight nutritional protein powder, the prepared protein powder has the advantages that the molecular weight is small, the composition of gamma-aminobutyric acid is scientific and reasonable, and is easy to absorb, the appearance is pure white and attractive, and no bean fishy smell and milk fishy smell can be generated; and the powder is easily dissolved into water, can be more quickly dissolved in cold water, is easy to disperse, and is particularly suitable for people who are lack of protein or feeble and sick, and tumor patients.

Description

technical field [0001] The invention belongs to the technical field of health care products, and in particular relates to a production method of low molecular weight nutritional protein powder. Background technique [0002] Protein is the main constituent material of the human body and the main material of human life activities. Protein plus nucleic acid is the main form of life. The original meaning of protein in ancient Latin is "primary". Although it is a part of nutrients, it is in a central position of various nutrients. Its main functions are: 1. It is used to make muscles, blood, skin and various body organs. 2. Help the body create new tissue to replace damaged tissue. 3. Deliver various nutrients to cells. 4. Regulate the balance of water in the body. 5. Make antibodies for the immune system to fight bacteria and infections. 6. Help wound blood coagulate and heal. 7. Produce enzymes in the body to help convert food into energy. The lack of protein in the hum...
