Abstract

To find the optimum proportion of perilla leaves for sulgidduk, rice cakes were prepared with different quantities of perilla leaves(0% 10% 20% 30% and 40% all w/w) for mechanical and sensory examinations. Moisture content of the control group was lower than that of the groups with perilla leaves. In color, L-value of the control group was higher than that of the other groups while a-value and b-value of the control group were significantly lower than that of the other groups(p<0.05). Springness, gumminess, and chewiness of the control group showed the highest value rather than those of the other groups. Hardness and adhesiveness of the control group was highest among the groups. Preference of color, taste, and total acceptability of sulgidduk with 20% perilla leaves was higher than that of the other groups. As a results above, perilla leaves can increase the acceptability of sulgidduk and 20% of perilla leaves would be proper to make sulgidduk.

본 연구는 설기떡을 깻잎량을 달리 첨가(0%, 10%, 20%, 30%, 40%)하여 제조한 후, 기계적 검사와 관능검사를 실시하여 깻잎 함유 설기떡 제조의 최적 배합비를 찾고자 하였다. 수분 함량은 깻잎 첨가군이 대조군보다 높았다. L값은 대조군이 가장 높았으며, a값과 b값은 대조군이 깻잎 첨가군에 비해 유의적으로 낮았다(p<0.05). 탄력성, 검성, 씹힘성이 깻잎 첨가량이 증가함에 따라 감소하고, 경도와 부착성은 대조군이 가장 높았다. 기호도 검사 결과, 색, 맛, 전체적 기호도는 깻잎 20% 첨가군이 가장 높게 평가되었다. 이상의 결과로 볼 때, 깻잎 첨가는 설기떡의 기호도를 높여 주고, 깻잎 첨가량 20%가 가장 적절한 것으로 사료된다.
