An object of the present invention is to provide a method for analyzing an isomer of triglyceride, a method for sorting oils and fats having different contents of an isomer of triglyceride, and a method for producing triglyceride of which an isomer can be fractionated. The present invention is a method for analyzing triglyceride, including a step of analyzing an isomer of triglyceride by supercritical fluid chromatography, in which multiple types of stationary phases are used in the supercritical liquid chromatography, and at least two stationary phases among the stationary phases have different chiral selectors in each of which one or more chlorines are bound to a polysaccharide derivative.

[Problem] Provision of a method for fractionating lipids using liquefied dimethyl ether as a solvent. [Means for Solving] To provide a method for fractionating a lipid using liquefied dimethyl ether as a solvent. [Solution] A method for fractionating a lipid, which comprises subjecting a microbial biomass to extraction using liquefied dimethyl ether as a solvent and then fractionating the lipid utilizing separation selectivity for the lipid. A method for producing a lipid, which comprises subjecting a microbial biomass to extraction using liquefied dimethyl ether as a solvent, then fractionating a portion of the lipid utilizing separation selectivity for the lipid to modify the fatty acid composition of the remainder of the lipid which remains in the microbial biomass, and then extracting the lipid having a modified fatty acid composition.

A dual phase re-circulating extraction apparatus comprises at least one extraction vessel, at least one separation chamber, and a circulation conduit configured to direct a process fluid into the extraction vessel, where it may come into contact with a source material to form a mixture, and is then passed to the separation chamber, where the process fluid separates from the extracted material, and the process fluid is recirculated back to the extraction vessel. The apparatus includes a gas pump, at least one heat exchanger, and a liquid pump, each connected to the conduit, to efficiently convert a relatively low pressure gas after separation to a relatively high pressure liquid or supercritical fluid for extraction. The apparatus can be configured to enable a batch mode process allowing continuous flow to the separators while the extractors are cycled online and offline in a sequence to enable servicing and reloading.

An extraction apparatus comprises an extraction vessel configured to remove an extracted material from a source material in contact with a process fluid to form a mixture. The apparatus further comprises a separation chamber and a process fluid circulation conduit, the conduit comprising a separation portion configured to receive the mixture and permit a portion of the extracted material to separate from the mixture within the separation chamber. The apparatus further comprises a temperature regulator configured to permit re-circulation of a temperature regulation fluid and regulate the temperature of the process fluid.
