Abstract

Methods of parboiling of paddy, to replace conventional steam-parboiling, and improve hydration ability in the parboiled rice were explored. Ratnachudi var., a medium-grained, high-amylose rice, was soaked in warm water to a saturation moisture level (approx. 30% wet basis). Soaked paddy was dried by either exposure to very hot air (150 degree -200 degree C) or roasting in hot sand (250 degree -300 degree C) for a few min. Under appropriate high-temp. conditions paddy was simultaneously dried and parboiled by both the above treatments. Parboiled rice so produced was examined for appearance (translucence, colour), milling breakage, alkali degradation pattern and starch retrogradation, and was quite comparable to normal steam-parboiled rice except that it had improved hydration ability due to reduced starch retrogradation. Possible development of the technique into a commercial process is indicated.
