DHA, docosahexaenoic acid, commonly known as brain gold, is an unsaturated fatty acid that is very important to the human body and is an important member of the omega-3 unsaturated fatty acid family. Docosahexaenoic acid (DHA) has the ability to regulate membrane-related physiological processes, prevent cardiovascular and cerebrovascular diseases, promote brain cell development, help cancer treatment, inhibit inflammation, improve senile dementia, anti-aging, help brain retina formation, genes Many important physiological regulation functions, such as expression and immune regulation, are essential unsaturated fatty acids that cannot be synthesized by the human body. They have a very broad market prospect in the food and health products industry.
The method of deep fermentation of Schizochytrium algae is used to produce DHA. The technology is advanced. The core of the technology is to obtain high-yield Schizochytrium algae strains through optimization and screening. The optimization of the fermentation process greatly improves the expression of DHA by this algae species. Ability to shorten the fermentation cycle and reduce production costs.
Through the innovation of extraction process, the original organic solvent extraction method is replaced by physical extraction method, so that the quality of the obtained fat is effectively improved without any organic solvent residue.
The obtained DHA oil has three forms: DHA hair algae oil, DHA refined oil, and DHA winterized oil.
DHA algae oil is the oil obtained after simple refining (dehydration and degumming) after physical extraction. The acid value and peroxide value of the oil are extremely low, which can meet the needs of enterprises with refining capabilities. Because the oil has not been decolorized and deodorized, its color is slightly reddish, and it has a distinctive odor of DHA algae oil.
DHA refined algae oil refers to the refined DHA wool algae oil obtained through dehydration, decolorization, deodorization and other processes. It can be supplied to milk powder companies, companies with embedding capabilities, and small-variety oil preparation companies. After the oil is refined, its color is very light, with a lighter DHA algal oil peculiar smell.
DHA winterization algae oil refers to cold filtration of the refined algae oil to filter out hard fatty acids that are easy to solidify. Due to the cold filtration treatment, the obtained DHA winterized algae oil can still maintain good fluidity even at a lower temperature. Therefore, the algae oil can be used for the production of DHA soft capsules, as well as for the production of microcapsule powder.
