초록

Durian 종자 전분의 입자크기범위는 약 $2.0-10.0\;{\mu}m$ 이었으며 구형과 다각형의 형태를 갖고 있었다. Durian종자, 옥수수, 고구마, 감자전분의 아밀로오스 함량은 28.3%, 27.5%, 20.3% 및 21.7%이었다. Durian 종자, 옥수수, 고구마, 감자전분의 blue value는 0.370, 0.368, 0.332 및 0.338이었으며, 알칼리도는 7.39, 9.02, 7.08 및 5.43이었다. Durian 종자 전분의 팽윤력과 용해도는 감자전분보다 낮았다. Durian 종자자전분의 X-선 회절도에 의한 결정성은 곡류전분과 같은 A형이었다. RVA로 측정한 durian 종자 전분의 호화개시온도 $(76.6^{circ}C)$는 옥수수$(73.0^{circ}C)$, 고구마$(72.3^{circ}C)$, 감자전분 $(70.2^{circ}C)$보다 높았으며 breakdown은 낮은 반면 setback은 높았다.

The granular size and shape of durian seed starch were $2.0-10.0\;{\mu}m$ and oval and polygonal. Amylose contents of durian seed, corn, sweet potato and potato starch were 28.3%, 27.5%, 20.3% and 21.7%, respectively. Blue value of durian seed (0.370) higher than that of corn (0.368), sweet potato (0.332), and potato starch (0.338). Alkali numbers of durian seed, corn, sweet potato and potato starch were 7.39, 9.02, 7.08 and 5.43, respectively. Swelling power of durian seed starch was similar to that of sweet potato starch. X-ray diffraction patterns of durian seed starch showed an A-type crystalline structure. According to pasting properties by Rapid Visco-Analyzer, the gelatinization temperature of durian seed starch $(76.6^{circ}C)$ was higher than that of corn $(73.0^{circ}C)$, sweet potato $(72.3^{circ}C)$ and potato starch $(70.2^{circ}C)$. The breakdown of durian seed starch were lower than that of corn, sweet potato and potato starch.
