Microalgae whole cell powder for making mammals produce DHA milk in high yield and preparation method thereof

Abstract

The invention discloses microalgae whole cell powder for making mammals produce DHA milk in high yield. The microalgae whole cell powder is prepared from raw materials of microalgae DHA cell pulp, an emulsifying agent, an antioxidant, a filler, a packing material, a dispersing agent and water. The preparation method comprises the following steps of: preparing the microalgae DHA cell pulp, and preparing an aqueous phase and a pulp phase; and mixing, emulsifying, homogenizing, spraying and premixing the aqueous phase and the pulp phase, and pelletizing to prepare the microalgae whole cell powder. The microalgae whole cell powder keeps the completeness thereof, is more easily absorbed by the mammals, and effectively keeps DHA components in the milk. Therefore, the DHA content of the finally secreted milk is much higher than that of common milk, the intake demands of all kinds of people on the DHA are met, the property is stable, and the biological functions of the DHA are fully exerted.

Description

technical field [0001] The invention relates to a whole cell powder of microalgae for high-yield DHA milk production of mammals such as cows and sheep, and a preparation method of the whole cell powder of microalgae. Background technique [0002] DHA, docosahexaenoic acid, commonly known as brain gold, is a polyunsaturated fatty acid that is very important to the human body and is an important member of the Omega-3 unsaturated fatty acid family. 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%. Intellectual and vision development of the fetus is very important. [0003] The lipid extract of microalgae DHA whole-cell product is directly added or microencapsulated into powder particles, and is widely added to dairy products, especially infant ...

AI Technical Summary

Problems solved by technology

However, the finished product of the cell-free extract of DHA is extremely unstable in nature and is easily affected by external physical and chemical factors. In particular, there are a series of problems in the process of adding to milk, such as spray drying and concentrated sterilization during the addition process. High, high pressure in the homogenization process, long time in the whole process, etc. will cause DHA price reduction, decomposition or odor, and microalgae powder is easy to absorb moisture, easy to be oxidized and smelly, cows are ruminants, and they are partially absorbed before being absorbed. It is converted into saturated fatty acid and produces substances harmful to the human body. The related processing technology and cost are very high
