preparation example Construction

[0014] The invention provides a method for preparing yogurt 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) The phosphatidylserine obtained in step (3), fresh milk, thickener, emulsifier, twisted sweetener and lactic acid bacteria are mixed and then fermented to obtain yoghurt.

[0019] In a preferred embodiment of the present invention, in order to further improve the human body's absorption of DHA and PS in yogurt, 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 consumpti...

Embodiment 1

[0030] 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), the phosphatidylserine rich in DHA is obtained; Yogurt A1 is obtained by mixing 1 g of ester, 0.5 g of twisted sweetener and 2 g of lactic acid bacteria and then fermenting.

Embodiment 2

[0032] 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 twisted sweet and 2.5g of lactic acid bacteria are mixed and fermented to obtain yogurt A2.

Abstract

The present invention discloses yogurt containing phosphatidylserine and a preparation method thereof. The preparation method comprises the following steps: DHA algae oil, polysorbate 80 and water are mixed to obtain a mixture A; L-serine, phospholipase D and a buffer solution are mixed, and the mixture is heated to obtain a mixture B; the mixture A and mixture B are mixed, the mixture is subjected to a solvent extraction to obtain DHA-enriched phosphatidylserine; the obtained phosphatidylserine, fresh milk, a thickener, an emulsifier, neotame and lactic acid bacteria are mixed, and the mixture is subjected to a fermentation to obtain the yogurt; and the prepared yogurt is rich in DHA and PS. By a synergistic effect of the DHA and PS, the yogurt can improve DHA stability and promote human body absorption.

Description

technical field [0001] The invention relates to the field of food preparation, in particular to yoghurt 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 to fu...
