Name of the ingredient
Docosahexaenoic acid (DHA) - rich oil derived from microalgae Schizochytrium sp. (AAN)
Definition of the ingredient
DHA-rich oil derived from microalgae Schizochytrium sp. is the winterised, deodorised oil derived from cultivated Schizochytrium sp. Due to taxonomical name changes made to the genus Schizochytrium, and for the purposes of this Compositional Guideline, the following genus and species are considered to be included: Schizochytrium aggregatum, Aurantiochytrium limacinum, Aurantiochytrium mangrovei, Oblongichytrium minutum, Oblongichytrium octosporum.
It contains docosahexaenoic acid at not less than 350 mg/g. Suitable standardising agents and antioxidants may be added.
