Abstract
Physico-chemical properties of the acetylated and raw starch were Investigated with the chucheongbyeo and samkangbyeo. The solubility and swelling power was increased by acylation reaction. The light transmittance was higher in the acetylated rice starch. The blue value of chucheongbyeo and samkangbyeo rice starches were lowered to 10.9% and 16.0%, respectively, by the acylation reaction. The alkali number was 7.6 in the chucheongbyeo rice starch and 7.2 in the samkangbyeo rice starch, whereas acylated starch in the same orders was 55 and 52, respectively. The hardness, adhesion, cohesion of starch gel was increased by the acylation reaction. The temperature of initial gelatinization of the acetylated chucheongbyeo and samkangbyeo rice starch was shown to
추청벼와 삼강벼를 원료로 하여 전분을 제조하고 그 전분을 이용하여 초산 쌀 전분을 제조하여 얻어진 초산 쌀 전분의 이화학적 성질을 검토하여 다음과 같은 결과를 얻었다. 초산 쌀 전분의 용해도와 팽윤력은 원료 전분에 비하여 높았으며 품종간에 약간의 차이를 나타내었다. 광투과도는 원료 전분에 비하여 높았으며 원료 전분은
