Product Introduction
Docose Hexaenoic Acid Oil Powder (DHA Oil Powder), is an unsaturated fatty acid that exists in almost every cell in the human body and is an important component of cell membranes. DHA is closely related to fetal brain development and retinal development. It can be considered an "essential fatty acid" for pregnant and breastfeeding women.
Primary Source of DHA
According to different sources, DHA can be divided into fish oil DHA and algal oil DHA.
1. Fish oil DHA
Fish oil DHA is mainly extracted from marine fish and has high fatty acid content. It is rich in omega-3 fatty acids, mainly EPA and DHA. Fish oil contains EPA. The main function of EPA is to reduce blood lipids and dilate blood vessels, so it is more suitable for middle-aged and elderly people.
Fish oil DHA may have problems with heavy metal contamination, just like eating sea fish. Fish do not produce omega-3 fatty acids, but they accumulate after ingesting planktonic algae or small fish. Fatty carnivorous fish, such as shark, swordfish, and tuna, are rich in omega-3 fatty acids. Due to their high position in the food chain, they also accumulate large amounts of toxins.
The FDA recommends reducing the intake of these carnivorous fish to avoid ingesting heavy metals.
2. Algal oil DHA
Algal oil DHA is first purified from microalgae by bioengineering methods, and then extracted and refined. It is rich in DHA and does not contain EPA. Therefore, the DHA content in algae oil is stable and does not contain fishy smell.
Algal DHA is generally safer than fish oil and is the only FDA-approved source of DHA for children.
Production Technology of Docose Hexaenoic Acid Oil Powder (Algal)
1. Engineering Bacteria Fermentation Technology
At present, the use of microalgae to produce DHA algal oil has been successfully commercialized at home and abroad. There are 3 methods for culturing DHA-producing microalgae: phototrophy (autotrophy), fermentation (heterotrophy) and co-culture, most of which are fermentation. Algal oil extraction technology has developed rapidly in recent years. The supercritical extraction technology of algae oil is gradually replacing the traditional n-hexane extraction method, which improves the safety of the product. The popularization and application of molecular distillation separation and purification technology has greatly increased the concentration of DHA in microalgal DHA oil.
2. Functional Factor Micro-encapsulation Technology
