  • Patent number: 11352651
    Abstract: The invention relates to the isolation of polyunsaturated fatty acids (PUFAs) from a lipids containing biomass. The main characteristics of the method are that a suspension of cells containing PUFAs is obtained and the cells are optionally lysed. The suspension is concentrated and then incubated for at least an hour at a controlled temperature while adding a specific range of base equivalents to biomass and maintaining a moderate pH. The isolation of lipid may be performed in the absence of organic solvents and without the addition of salt.

  • Patent number: 8753707
    Abstract: The present invention includes a solid fat composition that includes an oil having saturated fat and a microbial oil having a long chain polyunsaturated fatty acid and an emulsifier. In particular, the solid fat composition can have high levels of long chain polyunsaturated fatty acid and low amounts of emulsifiers. In preferred embodiments, the polyunsaturated oil is an unwinterized microbial oil. The invention also relates to methods for making such compositions and food, nutritional, and pharmaceutical products comprising said compositions. The present invention also includes a microbial oil product prepared by extracting an oil-containing fraction comprising at least one LC-PUFA from a microbial biomass, and treating the fraction by a process of vacuum evaporation, wherein the oil product has not been subject to one or more of a solvent winterization step, a caustic refining process, a chill filtration process, or a bleaching process.
