| During high-temperature treatment, starch is gelatinized and amylose can simultaneously form with lipids present at the rice bran to be the amylose-lipid complexes. The extent of complex formation closely depends on the degree of starch gelatinization. The objectives of this work were therefore to study the effect of drying media, hot air (HA), humidified hot air (HHA) and superheated steam (SHS), and operating condition on drying kinetics and starch hydrolysis or the glycemic index (GI) of brown rice. The experimental results revealed that the degree of gelatinization and degree of crystallinity of amylose-lipid complexes of treated brown rice by HHA and SHS drying had higher degree than HA drying because of condensation. The paddy dried by HHA at 150°C... |
