Abstract

The objective of this study was to evaluate the quality characteristics of lotus root Dasik prepared by different additions of lotus root powder (0%, 20%, 40%, 60%, 80%). As the level of lotus root powder in the formulation increased, the moisture contents of samples increased. Also, the L-, a-, and b-values of samples significantly decreased as the amount of lotus root powder increased. According to the results for mechanical characteristics, hardness, gumminess, springiness, cohesiveness, and chewiness decreased, whereas adhesiveness increased, as the amount of lotus root powder increased. The sensory evaluation results showed that the 40% lotus root sample received the highest preference scores; therefore, the 40% lotus root Dasik prepared with 60 g of flour, 40 g of lotus root powder, and 80 g of honey was chosen as the superior product.

본 연구는 기능성을 가지고 있는 연근을 우리나라 전통 한과류인 진말다식에 0%, 20%, 40%, 60%, 80%로 첨가하여 품질특성을 평가 한 후 연근 다식의 표준레시피를 제시하고자 하였다. 실험 결과를 요약하면 다음과 같다. 연근 다식의 수분함량은 연근가루 첨가량이 증가할수록 수분함량이 유의적으로 증가하였다. 연근 다식의 색도 변화에서는 연근가루의 첨가량이 증가할수록 L 값, a 값, b 값이 유의적으로 감소하는 경향이었다. 연근 다식의 물성에서는 연근가루의 첨가비율이 증가할수록 경도(hardness), 검성(gumminess), 씹힘성(chewiness), 탄력성(springiness)과 응집성(cohesiveness)은 감소하는 경향이었다. 부착성(adhesiveness)은 연근가루 첨가량이 증가할수록 증가하는 경향이었다. 연근 다식의 정량적 묘사분석에서 연근가루 첨가량이 증가할수록 색(color), 향(flavor), 맛(taste), 씹힘성(chewiness)의 강도가 높았으며, 부드러움(softness)은 시료 간에 유의적인 차이가 없었다. 기호도 검사에서는 연근가루 40% 첨가군(LR40)이 색, 향, 맛, 전체적 기호도에서 가장 높게 평가되었다. 이상의 연구를 통해 연근 다식으로 가장 적당한 제조 방법은 볶은 밀가루 60 g, 연근가루 40 g, 꿀 80 g으로 제조한 연근 다식이었다.
