Infant Nutrition Special Medical Food Sn-2 Position DHA High Content Omega-3 Algal Oil
Sn-2 DHA Algal Oil Series High Sn-2 DHA Containing Omega-3 Oil Derived from Microalgae / Enzymatic Position-Specific Ester Exchange + Physical Refinement Technology
Next-generation omega-3 ingredient with high content of Sn-2 DHA, which is close to the lipid structure of breast milk, achieving high absorption and high functionality.
This product is a high-functional omega-3 lipid material made from DHA algal oil derived from microalgae, using an enzyme-based positional selective ester exchange technology to highly selectively position DHA at the Sn-2 position. The fatty acid structure is in the natural triglyceride (TG) form, which has characteristics similar to the lipid structure in breast milk. DHA bound at the Sn-2 position is more efficiently utilized during the digestion and absorption process, and it is expected to have higher absorption compared to conventional random structure lipids. This product significantly increases the ratio of Sn-2 DHA, with the Sn-2 ratio reaching over 50% of the total DHA content, making it a high-functional lipid material. Additionally, by combining physical refining processes such as hydration and gum removal, alkaline deacidification, winterization, and decolorization, along with deodorization treatment, the peroxide value is kept low, and impurity indicators such as trans fatty acids, 3-MCPD esters, and glycidyl esters are properly managed. This next-generation DHA material is suitable for product development requiring high-functional lipids, such as infant formula, foods for special dietary uses, and special medical foods (FSMP).
