Abstract
The present invention discloses a microbial polyunsaturated fatty acid(PUFA)-containing oil with a high triglyceride content and a high oxidative stability. In addition, a method is described for the recovery of such oil from a microbial biomass deriverd from a pasteurized 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.
Claims21
A process for obtaining an oil comprising at least one polyunsaturated fatty acid (PUFA) from a microbial biomass, the process comprising:
- a) providing a biomass with a dry matter content of from 25 to 80%;
- b) granulating the biomass into granular particles;
- c) drying the granular particles to give dried granules;
- and
- d) extracting or isolating the oil from the dried granules.
