초록
떫은 감 분말의 첨가량 (0,5.10.15,20%)을 달리하여 설기떡의 품질 특성을 조사하였다. 감설기의 수분함량은 감 분말 첨가군 무 처리구에 비해 낮게 나타났으며, 환원당 ,유리당( fructose, glucose, sucrose), 무기질(Ca, K, Mg) 함량은 떫은 감 분말 함량이 증가할수록, 함량이 증가하는 경향을 보였다. 색도는 떫은 감분말의 첨가량이 증가할수록 L값은 낮아지고, a값과 b값이 증가하였고, texture 측정에서 adhesiveness, cohesiveness, gumminess, chewiness 값은 낮아지는 경향을 나타내었다. 관능검사 결과 떫은 감분말의 첨가가 무 처리구에 비해 전반적인 기호도가 높은 값을 나타났고, 15% 첨가구가 가장 높은 값을 나타내었다. 이상의 결과로 설기떡 제조시 첨가하는 설탕시럽 대용으로 여러 가지 기능성물질과 단맛을 함유하고 있는 떫은 감을 식품의 소재로 이용될 수 있는 충분한 가치가 있다고 사료 된다.
Abstract
This study investigated the quality characteristics of sulgidduck prepared by the addition of astringent persimmon powder. For Sulg : dduck, the amounts of added astringent persimmon powder were 0, 5, 10, 15, 20%. With the addition of astringent persimmon powder content, the moisture content of persimmon sulgidduck (sulgidduck prepared by adding astringent persimmon powder) decreased. With increasing addition of those, Reducing sugar, free sugar and mineral (Ca, K and Mg) of persimmon sulgidduck were increased significantly. L-value in color decreased, whereas a- and b-values were increased. Adhesiveness, cohesiveness, gumminess and chewiness in textural profile analysis were decreased. However, there is no respective comparison here. These results suggest that persimmon sulgidduck can be used as rice cakes commercially desired.
