Abstract
Physicochemical properties of heat-moisture (18, 21, 24 and 27%) treated naked barley (Youngsanbori) starch indicated that crystailinity of the starch was decreased upon treatment and water-binding capacity drastically increased as the moisture level increased. The swelling power was decreased, but the solubility increased by heat-moisture treatment. Apparent viscosity in aqueous sodium hydroxide solution was repressed as moisture-treatment level increased. Amylograph hot paste vicosities were decreased upon treatment except initial pasting temperature.
쌀보리인 영산보리 전분의 결정구조는 수분-열처리하지않은 것과 수분-열처리 한것 모두 A형을 나타냈고, 그 결정 정도는 수분-열처리 정도가 높아질수록 약해졌다. 물 결합능력은 수분-열처리 정도가 높아질수록 증가하였다. 팽윤력 및 용해도는 온도상승에 따라 증가하였으며 수분-열처리 정도가 높아질수록 같은 온도에서 팽윤력은 감소, 용해도는 점차 증가하는 경향을 나타냈다. 가열에 따른 호화도의 변화는 수분-열처리 하지않은 것과 수분-열처리 한것 모두
