There was a high correlation between the peak temperature for gelatinization and the apparent amylose content. The FT-IR peak at around +*** cm + increased in height with increased cooking time. The absorbance at this wavenumber reflects an increase in the amount of OH groups, which are hydrated due to gelatinization of starch. There was a high correlation in the degrees of gelatinization found by the FT-IR method and the BAP method. The calibration curve obtained in this study indicates that the measurement of the degree of gelatinization of cooked rice by FT-IR at around +*** cm + is an alternative to the conventional BAP method. It was also found that the hardness and stickiness of cooked rice as determined by sensory evaluation could be predicted based on the height of the FT-IR absorption peak.
