PREPARATION OF A MICROORGANIC POLYUNSATURATED FATTY ACID-CONTAINING OIL FROM LOW-TEMPERATURE-STERILIZED BIOMASS

摘要

PROBLEM TO BE SOLVED: To provide a novel polyunsaturated fatty acid-containing microorganic oil and a method for recovering the same polyunsaturated fatty acid-containing microorganic oil.SOLUTION: (1) A polyunsaturated fatty acid (PUFA)-containing microorganic oil having a high triglyceride content and a high oxidation stability and (2) a method for recovering the same microorganic oil from microorganic biomass derived from a low-temperature fermentation broth are hereby provided; the provided method includes a step of forming granular particles by subjecting the biomass to extrusion and, after the granular particles have been dried, extracting the microorganic oil from the dried granular particles by using an appropriate solvent.
