Embodiment 1

[0035] Weigh 70g of emulsifier (60g of modified starch, 10g of lecithin) and add it into deionized water, heat and mix at 40°C evenly, use a high-speed shearer to shear and stir the emulsifier to dissolve, and the shear rate is controlled at 5600 rpm. The cutting time was 10 minutes, followed by pasteurization, and the sterilized emulsifier solution was cooled to 30°C for later use. Dissolve 0.35g of antioxidants (including 0.15g of natural vitamin E and 0.2g of ascorbyl palmitate) in a small amount of docosahexaenoic acid oil at 50°C, cut until completely dissolved, cool to 30°C, and add 300g of mixed grease with 50% docosahexaenoic acid content, fully sheared and mixed to obtain a core material solution, then mixed the core material solution with an emulsifier solution, emulsified and sheared, and transferred to a high-pressure homogenizer for homogenization 1 times, the pressure is 40MPa. Add 730g of pasteurized wall material and stabilizer (including 410g of whey protein ...

Embodiment 2

[0037] Weigh 100g of emulsifier (sodium caseinate 100g), add it to deionized water, heat and mix at 50°C, and use a high-speed shearer to shear the emulsifier, the shear rate is controlled at 3000 rpm, and the shear time is 40 Minutes, followed by pasteurization, and cooling the sterilized emulsifier solution to 30°C for later use. Dissolve 0.4g of antioxidants (including 0.2g of natural vitamin E, 0.1g of rosemary extract, and 0.1g of tea polyphenols) in vegetable oil at 80°C, cut until completely dissolved, and add 35% 20% after cooling to 30°C 400g of mixed grease with Dicahexaenoic acid content is fully sheared and mixed to obtain a core material solution, then the core material solution is mixed with an emulsifier solution, emulsified and sheared, and transferred to a high-pressure homogenizer for homogenization 3 times at a pressure of 40MPa . Add 660g of pasteurized wall material and stabilizer (including 260g of desalted whey powder, 8060g of WPC, 50g of sucrose, 230g...

Embodiment 3

[0039]Weigh 40g of emulsifier (35g of sodium caseinate, 5g of modified starch), add it into deionized water, heat and mix evenly at 50°C, use a high-speed shearer to shear the emulsifier, and the shear rate is controlled at 2000 rpm, The shearing time is 20 minutes, followed by pasteurization, and the sterilized emulsifier solution is cooled to 30° C. for use. Dissolve 0.8g of antioxidants (including 0.5g of natural vitamin E, 0.2g of ascorbyl palmitate, and 0.1g of tea polyphenols) in vegetable oil at 60°C, cut until completely dissolved, and add 38% twenty-two after cooling to 30°C 400g of mixed grease with carbasexaenoic acid content was fully sheared and mixed to obtain a core material solution, then the core material solution was mixed with an emulsifier solution, emulsified and sheared, then transferred to a high-pressure homogenizer for homogenization 4 times at a pressure of 40 MPa. Add 810g of pasteurized wall material (including 260g of whey protein isolate, 8080g of...

Abstract

The present invention discloses a nanoscale docosahexaenoic acid emulsion and a preparation method thereof. The nanoscale docosahexaenoic acid emulsion comprises the following materials: 150 g to 500 g of docosahexaenoic acid as a core material, 0.1 g to 20 g of an antioxidant, 150 g to 200 g of a wall material, 75 g to 350 g of a stabilizer, 3 g to 100 g of a dispersing agent, 50 g to 150 g of an emulsifier, and up to 1000 g with water. The emulsion prepared in the present invention is an O/W type, and is principally prepared by mixing the docosahexaenoic acid oil, the emulsifier, the stabilizer, the wall material, an ionic dispersing agent and the water at a certain ratio, carrying out emulsifying, embedding, shearing and high pressure homogenizing, and finally getting an emulsion in which more than 80% of emulsified oil droplets have particle sizes of less than 100 nm, and have a normal distribution and a stable state. The present invention provides a docosahexaenoic acid emulsion formulation which can be dispersed in cold water, has good stability, and is stable to light, heat and oxygen. The nanoscale docosahexaenoic acid emulsion can be easily applied to industries of dairy, beverage, food, functional food, cosmetics and other related industries.

Description

Technical field: [0001] The invention relates to a nano-scale docosahexaenoic acid emulsion and a preparation method thereof, in particular to a nano-scale docosahexaenoic acid (DHA) that needs to be used in the industries of food, medicine, health care products and cosmetics Emulsion formulation and process and application. The product of the present invention is used as a nutrition fortifier. technical background: [0002] DHA (docosahexaenoic acid), commonly known as brain gold, belongs to the omega-3 series of long-chain polyunsaturated fatty acids, is a very important polyunsaturated fatty acid for the human body, and is an important fatty acid in the brain, nerves and visual cells Components, the content in the human cerebral cortex is as high as 20%, and the proportion in the eye retina is the largest, accounting for about 50%. Therefore, it has a significant effect on enhancing memory and thinking ability and improving intelligence, especially for the development of...
