Abstract

Palatability and texture analysis of nine Korean rice cultivars were investigated to select the most appropriate rice variety for the cooked-rice processing. The rice cultivars studied consisted of Samkwang, Seonpum, Wolbaek, Andabyeo, Dasan-1, Ilpum, Haiami, Jungsanggold and Chindle. They revealed the moisture, protein, amylose and starch contents of 10~12, 5~6, 12~19, and approximately 90%, respectively. Among the evaluated rice varieties, WB exhibited the lowest amylose content (12.7%) and Jungsanggold the next (17.2%). In the rapid-visco analyzer test, Jungsanggold, Chindle, Wolbaek and Seonpum revealed a low value of final and setback viscosities than other varieties. Using a toyo meter analyzer, Chindle, Haiami, Samkwang were selected as having high toyo palatability values, while Dasan-1, Wolbaek and Andabyeo revealed low values. Toughness and adhesiveness of all nine cooked rice varieties were highest in Jungsanggold, Chindle and Ilpum. Also, palatability of cooked rice was highest in the following order: Chindle (80.03) > Samkwang (76.21) > Jungsanggold (74.08). The results of this study suggest that Chindle may be effectively used to produce processed cooked rice.

본 연구는 가공밥용으로 적합한 품종을 선정하기 위하여 국립식량과학원에서 육성한 9개 쌀 품종의 단백질 함량, 수분관련 특성, 아밀로오스 함량, 호화점도 특성 분석 및 취반식미, toyo 윤기치, 식감 특성을 분석하였다. 쌀가루의 용해도는 선품과 친들이 6.98, 6.51%로 상대적으로 높았고, 총 전분 함량은 90% 내외를 나타났으며, 아밀로오스 함량은 월백이 12.74%로 가장 낮았고, 중생골드가 17.2%로 낮았다. 치반점도는 월백과 선품이 -89.94 및 -36.97 RVU로 쌀가루 반죽의 노화가 가장 느릴 것으로 생각되며, 월백, 친들, 하이아미의 최종점도가 각각 152.06, 160.66 및 191.03 RVU로 식은 밥의 노화가 가장 느릴 것으로 판단된다. Toyo 윤기치는 친들, 삼광, 하이아미가 좋게 나타났으며, 식미치는 친들(80.03)>삼광(76.21)>중생골드(74.08) 순으로 나타났다. 식감특성은 중생골드, 친들, 일품이 탄력성이 높으면서 부착성이 컸으며, 일품, 하이아미는 경도가 낮으면서 부착성과 찰기가 높았다. 전체적인 취반 식미 및 식감관련 평가 결과, 친들이 가공용으로 좋은 특성을 나타낼 것으로 판단되었다
