PREPARATION OF MICROBIAL POLYUNSATURATED FATTY ACID CONTAINING OIL FROM PASTEURISED BIOMASS

摘要

PROBLEM TO BE SOLVED: To provide a new microbial polyunsaturated fatty acid containing oil, and to provide a method for the recovery of such microbial polyunsaturated fatty acid containing oil.

SOLUTION: The present invention discloses (1) the microbial polyunsaturated fatty acid(PUFA)-containing oil with a high triglyceride content and a high oxidative stability, and (2) the method for the recovery of such oil from a microbial biomass derived from a pasteurised fermentation broth, wherein the microbial biomass is subjected to extrusion to form granular particles, dried and the oil then extracted from the dried granules using an appropriate solvent.
