Problems solved by technology

[0005] DHA oil is easily oxidized when exposed to air, and cannot withstand high temperature, so it is difficult to directly use it in infant formula under the condition of effectively maintaining its activity
Patent CN1731983A and patent CN1927050A disclose a method for effectively maintaining the activity of DHA, that is, adding DHA oil to food as a nutritional enhancer after microencapsulation, although this relatively effectively solves the defect of its easy oxidation and deactivation , to maintain its activity in use, but there are also defects that the addition and use process is cumbersome and difficult to mix evenly, and the energy consumption in the process of DHA oil microencapsulation is extremely high, which greatly increases the production cost

preparation example Construction

[0045] The preparation method of docosahexaenoic acid emulsion of the present invention, the steps are:

[0046] 1) Oil phase part: add docosahexaenoic acid oil with a concentration higher than 30% into the oil phase emulsifier, coating agent, and antioxidant according to the above weight ratio, and heat the oil bath to 40-70°C to dissolve it , to make oil phase product A;

[0047] 2) Water phase part: Add water phase emulsifier, stabilizer and dispersant into water according to the above weight ratio, fully stir, heat to 60-90°C, keep for 20-60min, and make water phase product B;

[0048] 3) After the temperature of the water phase product B drops to 40-70°C, slowly add A to B, perform primary emulsification with a high-speed shearing machine, and obtain product C;

[0049] 4) pressure homogenize product C to obtain product D;

[0050] 5) After sterilizing and cooling the product D, the product E is obtained, which is the docosahexaenoic acid emulsion.

[0051] In the prep...

Abstract

The invention discloses an emulsion of micron-sized docosahexenoic acid (DHA) and a preparation method thereof. The emulsion of micron-sized docosahexenoic acid (DHA) comprises: 50g to 150g of DHA, 10g to 50g of coating agent, 14g to 130g of oil phase emulsifier, 8g to 50g of aqueous phase emulsifier, 75g to 350g of thickening and stabilizing agent, 10g to 100g of dispersant and 0.5g to 20g of antioxidant; water is added for obtaining solution of 1000g. The emulsion of the invention is O / W type and mainly characterized in that the emulsifiers and the thickening and stabilizing agent are emulsified with the DHA and water according to certain proportions so as to obtain the emulsion with stable status and emulsified particle diameter less than 1 micron. The invention provides a prescription of a DHA emulsion capable of dispersing in cold water, provided with good stability and is stable against light, heat and oxygen and can be conveniently used in beverage, food and other relevant industries.

Description

technical field [0001] The invention relates to a micron-sized docosahexaenoic acid emulsion and a preparation method thereof, in particular to a docosahexaenoic acid emulsion and a process for use in the industries of food, medicine, health care products and cosmetics and application. The present invention is used as a nutrition enhancer. technical background [0002] Docosahexaenoic acid is an omega-3 series of long-chain polyunsaturated fatty acids (PUFA). DHA is an essential polyunsaturated fatty acid for the human body. It is an important fatty acid component in the brain, nerves and visual cells. It plays an important role in the normal performance of human physiological functions and the prevention and treatment of various diseases, especially in the brain and visual system of infants. play an important role in development. DHA mainly exists in the gray matter part of the brain. It is the main lipid component in the nerve cell membrane of the human brain, and it is...
