Abstract: The present invention relates to a process for refining glyceride oil by size exclusion chromatography to obtain a triglyceride enriched fraction. The process comprises passing a glyceride oil through a size exclusion column packed with porous particles having a mass weighted mean particle size of 20 to 1,000 ?m and an average pore size of 10 to 150 A without using any solvent and collecting an eluate fraction enriched in triglyceride. The process may further comprise passing a solvent through the size exclusion column after the eluate fraction enriched in triglyceride is collected to obtain a partial glyceride enriched fraction. The process can suitably be used to produce triglyceride enriched fraction having a triglyceride content that is close to 100%.

Abstract: The present invention relates to the production of oil and fat containing acylglycerol esters including diacylglycerols, medium-chain and long-chain fatty acid triacyglycerols comprising esterification reaction between an acyl group donor and an acyl group acceptor in the presence of a heterogeneous chemical catalyst consisting of an ion-exchange resin preparation to obtain a reaction fluid that is further subjected to dehydration and at least one separation method, thus producing diacylglycerols and/or medium-chain and long-chain fatty acid triacyglycerols at a high yield in a short period of time.

Abstract: The present invention provides a process for producing a diacylglycerol, which comprises, reacting triacylglycerol with water and an enzyme preparation to obtain a mixture comprising of diacylglycerol, monoacylglycerol and free fatty acid; removing water content in the mixture by way of dehydration; and separating monoacylglycerol, free fatty acid and residual triacylglycerol by at least one separation method to obtain a high-purity diacylglycerol. An oil or fat composition comprising of diacylglycerol obtained from the process and phytosteryl esters and/or ferulic acid esters in an amount of from 0.5% to 25% by weight of diacylglycerol is also provided.
