MANUFACTURING METHOD OF MODIFIED OIL AND FAT COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide an oil and fat composition decreased in a 3-MCPD fatty acid ester content, and an oil and fat composition decreased in a 3-MCPD fatty acid ester content and in a glycidol fatty acid ester content.

SOLUTION: Oil and fat containing more than 0.300×10-5mol/kg of the total of 3-MCPD and a 3-MCPD fatty acid ester is subjected to chemical transesterification in the presence of sodium methylate so that the transesterification reaction rate is at least 90%, subsequently treated with acid activated clay and then subjected to deodorization at a temperature of 200°C or higher and 230°C or lower to give an oil and fat composition having a total content of 3-MCPD and the 3-MCPD fatty acid ester of at most 0.30×10-5mol/kg and a total content of glycidol and the glycidol fatty acid ester of at most 1.35×10-5mol/kg.
