Japanese Patent JP2603830
Kind Code:
B2
Abstract:
PURPOSE:To obtain a novel stable fat and oil, utilizable in the field of medicines and foods and having excellent digestibility and absorbability, by subjecting a glyceride and fatty acid, etc., to ester interchange reaction and fractionating the resultant reaction product by reversed phase type partition column chromatography. CONSTITUTION:A glyceride and another glyceride or a fatty acid (ester) are subjected to ester interchange reaction in the presence of a catalyst having specificity for the 1,3-positions and, as necessary, the resultant reaction product is treated with a hydrous solvent to remove free fatty acids and/or partial glycerides. The ester interchange reaction product of hydrous treated substance thereof is fractionated by reversed phase partition chromatography to afford the aimed fat and oil having 2-16C fatty acid residue in the 1,3-positions of the glyceride and >=8C fatty acid residue having a larger number of carbon atoms. in the 2-position than that in the 1,3-positions.
