preparation example Construction

[0037] The present invention also provides a method for preparing milk containing unsaturated fatty acids, comprising the following steps:

[0038] (1) Take 2 / 3 of the qualified raw milk and raise the temperature to 60-75°C. Add emulsification stabilizer, DHA algae oil, fish oil and compound nutrients through a water-powder mixer, and keep stirring for 10-15 minutes;

[0039] Preferably, the emulsification stabilizer and compound nutrients are pre-mixed and added to reduce the loss of nutrients;

[0040] (2) The material obtained after mixing in step (1) is cooled to below 10°C and placed in the batching tank;

[0041] (3) Standardization: add the remaining 1 / 3 raw milk and essence into the batching tank and stir for 10-15 minutes to obtain batched milk;

[0042] (4) Homogenize the batch milk obtained in step (3) after being heated to 60-75° C., and the homogenization pressure is 18-20 MPa. Single homogenization is used to reduce the acceleration of homogenization on the ox...

Embodiment 1

[0057] The embodiment of the present invention provides a modified milk containing unsaturated fatty acid and a preparation method thereof. It consists of raw materials with the following mass fractions: 80% raw milk, 0.1% fish oil, 0.05% DHA algae oil, 0.1% emulsion stabilizer, 0.01% antioxidant, 0.01% complex nutrients and 0.02% food flavor, supplemented to 100% water.

[0058] Both the fish oil and the DHA algae oil belong to the type of high-carrying oil, the DHA and EPA content in the fish oil is more than 14.5%, and the DHA content in the DHA algae oil is more than 40%.

Abstract

The invention discloses modified milk containing unsaturated fatty acid and a preparation method of the modified milk. The modified milk is prepared from the following raw materials in percentage by mass: 80-95 percent of raw milk, 0.1-0.3 percent of fish oil, 0.05-0.1 percent of DHA algae oil, 0.1-0.2 percent of an emulsion stabilizer, 0.01-0.05 percent of an antioxidant, 0.01-0.1 percent of a compound nutrient, 0.02-0.1 percent of edible essence and the balance of water, totaling 100 percent. The preparation method comprises the following steps: heating 2 / 3 of raw milk, adding the emulsion stabilizer, DHA algae oil, fish oil and composite nutrients, and stirring while keeping the temperature to obtain a mixed solution A; cooling the mixed solution A to below 10 DEG C, and putting the mixed solution A into a batching cylinder; adding edible essence and the rest 1 / 3 of raw milk into the mixing tank, and stirring for 10-15 minutes to obtain ingredient milk B; homogenizing the ingredientmilk B to obtain a mixed solution C; and sterilizing, cooling and filling the mixed solution C to obtain the product. The modified milk disclosed by the invention is rich in DHA and EPA and good in stability.

Description

technical field [0001] The invention belongs to the technical field of dairy products, and in particular relates to modulated milk containing high content of DHA and EPA and a preparation method thereof. Background technique [0002] Polyunsaturated fatty acids usually include two series of omega-3 and omega-6. Docosapentaenoic acid (DHA) and docosahexaenoic acid (EPA) both belong to omega-3 unsaturated fatty acids, and these two fatty acids are the two most important unsaturated fatty acids for the human body. Studies have shown that the human body cannot synthesize DHA and EPA by itself and can only be obtained through food. A number of random meta-analysis studies have shown that the intake of unsaturated fatty acids such as DHA and EPA can significantly reduce the incidence of cardiovascular diseases such as heart disease in the population. At the same time, the DHA in algae oil and fish oil can also help the development of the brain and retina. Countries such as the E...
