METHOD FOR DISCRIMINATING FAT AND THE LIKE USING LINEAR DISCRIMINATION FORMULA BY MULTIVARIATE ANALYSIS FOR GEL INDEX

摘要

PROBLEM TO BE SOLVED: To provide a method for discriminating an oil expression raw material for forming a no-gelation fat without performing a cooling test.SOLUTION: The method for discriminating an oil expression raw material for forming a fat liquid at room temperature and not gelated even in a long term storage at low temperature comprises: extracting an oil content from the raw material; determining at least one selected from proportions of (1) PO, PStO, PStL, POL, StO, StOL, OL, LLL and (LLn+OLn) included in the extracted oil content to use them for a gel index; determining at least one selected from proportions of (2) SU, SUand UUU to use them for a gel index; or (3) determining at least one selected from proportions of SU/(SU+UUU), PL/SUand SO to use them for a gel index.
