DIHOMO-GAMMA-LINOLENIC ACID-CONTAINING MICROBIAL OIL AND DIHOMO-GAMMA-LINOLENIC ACID-CONTAINING MICROBIAL BIOMASS

A microbial oil comprises dihomo-γ-linolenic acid in fatty acid alkyl ester form and/or in free fatty acid form at a content of at least 50% by weight of the total weight of fatty acids in the oil. The content of thermally-produced fatty acid having from 16 to 22 carbon atoms, generated by heat asso...

Beschreibung
Zusammenfassung:	A microbial oil comprises dihomo-γ-linolenic acid in fatty acid alkyl ester form and/or in free fatty acid form at a content of at least 50% by weight of the total weight of fatty acids in the oil. The content of thermally-produced fatty acid having from 16 to 22 carbon atoms, generated by heat associated with distillation in the production method, is from 0.0001% by weight to 3.0% by weight of the total weight of fatty acids in the microbial oil. A production method thereof comprises providing a starting oil containing dihomo-γ-linolenic acid in alkyl ester form and/or a free fatty acid form, obtained from microbial biomass; performing rectification of the starting oil under specific conditions; and obtaining the aforementioned microbial oil. Other aspects are a concentrated microbial oil, and use of the described oils as an agent for treating or preventing inflammatory disease.
