Polyunsaturated fatty acid-containing oil product and uses and production thereof

摘要

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.

主权项

1. A food product, comprising:
an isolated stearin fraction of a microbial oil product, wherein the isolated stearin fraction comprises at least one LC-PUFA; and a food or liquid component, wherein the LC-PUFA comprises at least 20 carbons, wherein the oil product has a free fatty acid content of less than about 0.5 wt. %, and wherein the isolated stearin fraction has a solid fat content greater than about 25% when stored at a temperature of less than about 25° C.
