Title:
DETERMINATION METHOD AND PRODUCTION METHOD FOR OIL AND FAT COMPOSITION
Document Type and Number:
Japanese Patent JP2018136151
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a determination method of an oil and fat composition for accurately determining a content ratio of fats and oils in a fat and oil composition and a production method of an oil and fat composition for producing an oil and fat composition having a desired content ratio.SOLUTION: In the determination method of an oil and fat composition, two or more selected from the group consisting of: oil and fat A; oil and fat B; and an oil and fat composition containing the oil and fat A and the oil and fat B; are excited at a portion or entire range of excitation wavelength from 250 to 700 nm, and their fluorescent fingerprints are obtained by measuring all or part of the fluorescence wavelength of 250 to 800 nm by using a spectrofluorometer. By comparing each of the fluorescent fingerprints thus obtained, one or more characteristic peaks of the oil and fat A and/or the oil and fat B are selected. Fluorescence intensity of the fat or oil composition to be determined is measured at wavelength of one or more of the peaks (excitation wavelength, fluorescence wavelength) by using the spectrofluorometer. The content ratio of the oil and fat A and/or the oil and fat B in the fat and oil composition to be determined is thereby determined.SELECTED DRAWING: Figure 4
