  • Patent number: 10342772
    Abstract: Processes are disclosed for obtaining a lipid from a cell by lysing the cell to form a lysed cell composition, adding an acid to lower the pH of the lysed cell composition, and demulsify the lysed cell composition, and obtaining the lipid from the demulsified lysed cell composition. Also disclosed are lipids prepared by the processes of the present invention wherein the lipids have a particular anisidine value, peroxide value, and/or phosphorus content.

  • Patent number: 9796658
    Abstract: The present invention includes methods for producing and purifying esters of polyunsaturated fatty acids that include reacting a composition having triglycerides with polyunsaturated fatty acid residues in the presence of an alcohol and a base to produce an ester of a polyunsaturated fatty acid from the triglycerides. The composition can be a polyunsaturated fatty acid-containing composition that has not been conventionally processed. The reacted composition can be further processed by distillation.

  • Publication number: 20080026103
    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.
