| Outline of Final Research Achievements |
For the purpose of development of non-destructive Raman spectroscopic method for solid fat content (SFC) measurement, 120 samples of edible oils and fats were subjected to Raman and NMR measurements. Raman spectroscopic index αC value, which represents a degree of crystallinity of fats, obtained high correlation with SFC values measured by NMR (P <0.001) and the coefficient of determination (R2) was 0.987. In order to consider how much the accuracy of SFC prediction by αC, predicted-SFC and measured-SFC values were subjected to regression analysis. As a result, measured-SFC values were in the range of 95% confidence interval of the predicted value. αC was able to predict SFC about ± 5% accuracy. Moreover, using fat standard samples with simple crystal polymorphism, a different regression equation was obtained; It may be due to differences in crystal polymorphic types of fat standard samples and edible fats.
