preparation example Construction

[0014] The invention provides a method for preparing milk powder containing phosphatidylserine, the preparation method comprising:

[0015] (1) DHA algae oil, polysorbate 80 and water are mixed to obtain mixture A;

[0016] (2) Mix L-serine, phospholipase D and buffer solution, and heat to obtain mixture B;

[0017] (3) After mixing mixture A and mixture B, solvent extraction is performed to obtain phosphatidylserine rich in DHA;

[0018] (4) Mix the phosphatidylserine obtained in step (3), fresh milk, thickener, emulsifier, non-dairy creamer and animal protein, homogenize and spray dry to obtain milk powder.

[0019] In a preferred embodiment of the present invention, in order to further improve the human body's absorption of DHA and PS in milk powder, relative to 100 parts by weight of water, the amount of DHA algae oil is 0.2-0.6 parts by weight, and the poly The consumption of sorbide 80 is 2-8 parts by weight, relative to the buffer solution of 100 parts by weight, the ...

Embodiment 1

[0031] 0.2gDHA algae oil, 2g polysorbate 80 and 100g water are mixed to obtain mixture A; 10gL-serine, 0.5g phospholipase D and 100g buffer solution (buffer solution is composed of chloroform and ethanol, and the volume ratio of chloroform and ethanol 1:2) mixing and heating (the heating temperature is 40°C and the heating time is 4h) to obtain mixture B; mix mixture A and mixture B (mixture A and mixture B are mixed according to the volume ratio of 1:20) After extraction with a solvent (the solvent is obtained by mixing 20g ethanol, 10g ether and 100g water), phosphatidylserine rich in DHA is obtained; Milk powder A1 was obtained by mixing 1 g of ester, 0.5 g of non-dairy creamer and 2 g of animal protein and then homogenizing and spray drying (the pressure of homogenization was 15 Mpa; the pressure of spray drying was 0.5 Mpa).

Embodiment 2

[0033] 0.6gDHA algae oil, 8g polysorbate 80 and 100g water are mixed to obtain mixture A; 20gL-serine, 5.5g phospholipase D and 100g buffer solution (buffer solution is made up of chloroform and ethanol, and the volume ratio of chloroform and ethanol 1:5) mixing and heating (the heating temperature is 60°C, and the heating time is 8h) to obtain mixture B; mix mixture A and mixture B (mixture A and mixture B are mixed according to the volume ratio of 1:40) After extraction with a solvent (the solvent is obtained by mixing 40g ethanol, 20g ether and 100g water), the phosphatidylserine rich in DHA is obtained; 2g, 0.7g of non-dairy creamer and 2.5g of animal protein were mixed, homogenized and spray-dried (the pressure of homogenization was 20Mpa; the pressure of spray-drying was 0.8Mpa) to obtain milk powder A2.

Abstract

The invention discloses milk powder containing PS (phosphatidylserine) and a preparation method of the milk powder. The preparation method comprises the following steps: DHA algal oil, polysorbate 80 and water are mixed, and a mixture A is obtained; L-serine, phospholipase D and a buffer solution are mixed and heated, and a mixture B is obtained; the mixture A and the mixture B are mixed and subjected to extraction with a solvent, and DHA-rich PS is obtained; the DHA-rich PS, raw fresh milk, a thickener, an emulsifier, non-dairy creamer and animal protein are mixed, an obtained mixture is subjected to homogenization and spray drying, and the milk powder is obtained. The prepared milk powder contains rich DHA and PS, and by means of the synergistic effect of the DHA and the PS, the stability of the DHA can be improved, and absorption of the DHA by a human body can be promoted.

Description

technical field [0001] The invention relates to the field of food preparation, in particular to milk powder containing phosphatidylserine and a preparation method thereof. Background technique [0002] Phosphatidylserine (Phosphatidylserine, PS) is an important component of mammalian cell membrane phospholipids, especially in brain tissue, PS can pass through the blood-brain barrier smoothly, and can enter the brain within a few minutes after being absorbed. Cognition, emotion, learning, memory and other brain functions are closely related, and have been applied to improve Alzheimer's disease, treat depression, relieve mental stress and physical fatigue, etc. Docosahexaenoic acid (docosahexaenoic acid, DHA) has a significant effect on the brain, intelligence and vision protection. Free DHA is unstable and easy to oxidize, and taking it alone will increase the burden on the gastrointestinal tract. How to synthesize DHA and PS and apply it in the field of food manufacturing t...
