Problems solved by technology

However, DHA algae oil is easily oxidized when exposed to the air, is easily affected by external physical and chemical factors, and cannot withstand high temperatures, so it is difficult to directly use it in various beverages under the condition of effectively maintaining its activity
As for the microencapsulated DHA algae powder, although it is relatively effective to solve the defect of its easy oxidation and deactivation, and maintain the activity of DHA in use, it also has the disadvantages of cumbersome addition and use process and difficulty in mixing uniformly. The embedding material is not ideal, and its shelf life in liquid beverages has certain limitations, and the energy consumption in the process of DHA algae oil microencapsulation is extremely high, which greatly increases the production cost

Embodiment 1

[0020] It is 22% DHA emulsion that the addition of DHA algae oil is prepared, and its each raw material content is as follows:

[0021] DHA algae oil 22Kg

[0022] Packaging material 27.88Kg

[0023] Water 45Kg

[0024] Antioxidant 0.02Kg

[0025] Stabilized thickener 3Kg

[0026] Emulsifier 0.1Kg

[0027] Adhesive 2Kg

[0028] The first step is to make the water phase: dissolve the packaging material, emulsifier, stable thickener, and adhesive in water and stir for 5 minutes ± 1 minute. After stirring and dissolving, import it into an emulsification shear tank and heat it at 68 ± 5°C to emulsify and shear 10 to 20 minutes to make the packaging material completely gelatinized;

[0029] And, make the oil phase: add antioxidants to DHA algae oil and stir well;

[0030] The second step, emulsification of the mixture: slowly add the oil phase to the water phase during the stirring process, stir evenly, keep the temperature at 50-60°C throughout the process, and emulsify for...

Abstract

The invention discloses DHA (Docosahexaenoic Acid) emulsion, comprising the following components in the mass percentage: 22-27% of DHA algal oil, 27-32% of packaging material, 40-45% of water, 0.02-0.05% of antioxidant, 3.0-5.0% of stabilizing and thickening agent, 0.1-0.3% of emulsifying agent and 2.0-3.0% of adhesive. The DHA emulsion is prepared by the following steps: firstly preparing a water phase and an oil phase, then mixing the materials, emulsifying, homogenizing and finally sterilizing. In application of preparing DHA beverages, the DHA emulsion is used as a nutrition enhancer and added to liquid milk, acid milk, various milk beverages, juice beverages, nutritional and sports beverages and foods in the proportion of 40-180mg / 100g. The production process of the DHA emulsion is simple and feasible, the absorption and utilization ratio of DHA in a human body is high. When in use, the DHA emulsion has good dispersing performance, stable light resistance, oxygen resistance, acid and alkaline resistance and the like the functions of enhancing memory and thought and improving intelligence, high nutritional value, as well as extremely wide use range.

Description

technical field [0001] The invention relates to a DHA emulsion and its production method and application. Background technique [0002] DHA, docosahexaenoic acid, commonly known as brain gold, is a polyunsaturated fatty acid that is very important to the human body. It belongs to an important member of the Omega-3 unsaturated fatty acid family. When it is deficient, it can cause a series of symptoms, including growth Developmental delay, abnormal scaly skin, infertility, mental retardation, etc. DHA is a main element for the growth and maintenance of nervous system cells. It is an important component of the brain and retina. Its content in the human cerebral cortex is as high as 20%, and it accounts for the largest proportion in the retina of the eye, accounting for about 50%. Therefore, for The human body, especially the infant's intelligence and vision development is very important. [0003] DHA-rich Schizochytrium sp. is fermented, concentrated and separated to obtain m...
