Abstract
The physicochemical properties of starches from dry(Suwon 147) and moist type(Hwangmi) sweet potato were investigated and molecular structural properties of their amylopectins were also studied by gel chromatography. Suwon 147 starch bad lower swelling power and higher gelatinization temperature than Hwangmi starch.
한국산 고구마 중 분질인 수원 147과 점질인 황미로부터 전분을 분리하고 이화학적 특성을 비교하였으며 아밀로펙틴의 분자구조적 성질을 조사하였다. 수원 147 전분은 황미전분에 비하여 팽윤력이 낮고 호화개시온도가 높았다.
