A microbial oil comprising: a specific amount of at least one polyunsaturated fatty acid having at least 20 carbon atoms in fatty acid alkyl ester form and/or in free fatty acid form; and specific amount of thermally-produced fatty acid having from 16 to 22 carbon atoms in a fatty acid alkyl ester form and/or a free fatty acid form. A production method thereof comprising: providing a starting oil containing at least one polyunsaturated fatty acid having at least 20 carbon atoms in an alkyl ester form and/or a free fatty acid form obtained from microbial biomass; performing a rectification of the starting oil under specific conditions; and obtaining the aforementioned microbial oil. A concentrated microbial oil obtained using the production method described above, and a production method thereof. An agent for treating or preventing an inflammatory disease comprising the microbial oil or the concentrated microbial oil.

A flavor improver for a polyunsaturated fatty acid-containing fat or oil, containing a basic peptide; and a polyunsaturated fatty acid-containing fat or oil composition, containing a fat or oil containing a polyunsaturated fatty acid having 18 or more carbon atoms and two more double bonds, a basic amino acid and/or a basic peptide, and an emulsifying agent. The flavor improver for a polyunsaturated fatty acid-containing fat or oil and the polyunsaturated fatty acid-containing fat or oil composition of the present invention can suppress the generation of unpleasant taste and flavor from the polyunsaturated fatty acid over a long time period.

Recombinant DNA techniques are used to produce oleaginous recombinant cells that produce triglyceride oils having desired fatty acid profiles and regiospecific or stereospecific profiles. Genes manipulated include those encoding stearoyl-ACP desaturase, delta 12 fatty acid desaturase, acyl-ACP thioesterase, ketoacyl-ACP synthase, and lysophosphatidic acid acyltransferase. The oil produced can have enhanced oxidative or thermal stability, or can be useful as a frying oil, shortening, roll-in shortening, tempering fat, cocoa butter replacement, as a lubricant, or as a feedstock for various chemical processes. The fatty acid profile can be enriched in midchain profiles or the oil can be enriched in triglycerides of the saturated-unsaturated-saturated type.

The invention belongs to the technical field of phospholipid processing, in particular to a self-aggregating hydrous phospholipid and a preparation method thereof. The self-aggregating hydrous phospholipid, the main components of the self-aggregating hydrous phospholipid are phospholipids, oil and water, the water content is 70-80 g/100 g, and the acetone-insoluble content on a dry basis is 92.5-95.5 g/100 g. Preferably, the self-aggregating hydrous phospholipid is a brown translucent fluid. The present invention is used to overcome the defects of low acetone-insoluble content of the hydrous phospholipid prepared by the existing method and the long-term dependence of the industry on the solvent method to prepare powder phospholipid, and to solve the technical problem that the hydration method powder phospholipid cannot realize industrial production.
