What is Arachidonic acid Powder?

Arachidonic acid(ARA) Powder is a white or pale yellow flowing powder, with the smell of this product unique. It belongs to Omega-6 unsaturated fatty acid, which is an essential fatty acid in the human body, and is also the most abundant and widely distributed polyunsaturated fatty acid in the human body. In the human body, it can regulate the immune system, protect liver cells, promote digestive function, and promote the normal development of fetuses and babies. It can only be synthesized in small amounts in the human body.

Functions of Arachidonic acid (ARA)

function ARA is one of the most important polyunsaturated fatty acids that make up the brain and retina. In the brain and nerve tissue, ARA content accounts for 40% to 50% of polyunsaturated fatty acids, and even as high as 70% in nerve endings. As an important structural lipid component, ARA mainly exists in the phospholipids of the cell membrane, and plays an important role in maintaining the integrity of the cell membrane, regulating the plasticity, permeability and fluidity of the cell membrane.

ARA and DHA are important polyunsaturated fatty acids that affect human intellectual development. DHA mainly exists in human brain cells and retina, and plays an extremely important role in cell division, proliferation, nerve conduction, and synapse growth and development. The main stages of human brain development are infancy and early childhood, during which the weight of the brain increases exponentially. At this time, about a quarter of the brain's solid matter is formed from phospholipids, and ARA is one of the main long-chain polyunsaturated fatty acids that make up phospholipids in the cerebral cortex.

Applications

1. Arachidonic acid Powder for Infant formula application.

2. Liquid milk application.

3. Yogurt application.

4. As the new resource food for application.

Preparation methods

1. Natural extraction method.

The natural sources of arachidonic acid mainly include animal liver, fish oil and egg yolk. But the ARA content in animal tissue is very low, about 2%. It is easily affected by environmental factors such as climate and origin.

2. Microbial fermentation method.

Microbial fermentation to produce arachidonic acid is to obtain ARA oil through the processes of culture, fermentation, filtration, washing, bacterial cells, extraction and purification.

Advantages of ARA Powder

1. Low surface oil.

2. Good stability.

3. Good liquidity.

4. Low peroxide value.

5. Good odor and taste.

6. Suitable for pregnant women, mothers, infants and young children.
