Quality and Pasting Properties of Traditional Olbyeossal

This study investigated the physicochemical properties of traditional Olbyeossal(Korean-style parboiled waxy rice) and other rices(dried cooked rice, germinated brown rice, and waxy brown rice). Olbyeossal had a moisture content of 12.7% a crude fat level of 1.0%, a crude ash content of 0.9%, and a crude protein value of 6.3%. The color values were 58.63(L value), 0.83(a value) and 21.73(b value). The water adsorption index(WAI) of Olbyeossal was 6.2g/g after 40 min steeping at room temperature, which was much higher than the WAI of the other rices. The hardness of Olbyeossal(10.5 kgf) was higher than those of other rices( kgf). The initial pasting temperatures of Olbyeossal, dried cooked rice(DCR), germinated brown rice(GBR) and waxy brown rice(WBR) were , respectively. The breakdown and total setback viscosities of Olbyeossal(70 B.U., 50 B.U.) and WBR(10 B.U., 30 B.U.) were lower than those of DCR(120 B.U., 275 B.U.) and GBR(142 B.U., 340 B.U.).
