Abstract

The objective of this study is to investigate the quality characteristics of yanggeng prepared with different amounts of Crataegi fructus extracts(CFE; 0, 5, 10, 15, 20). Increasing the amount of CFE in the yanggeng tended to increased the moisture and acidity, while it decreased the level of pH. In chromaticity determination, the values of lightness(L) and yellowness(b) showed a decrease. However, the value of redness(a) increased by increasing levels of CFE. In addition, hardness increased by increasing levels of CFE. Although regarding texture profile analysis, hardness and springiness of yanggeng were increased, adhesiveness and cohesiveness of yanggeng were decreased. Cohesiveness shown similar result compared to the control and CFE added treatments. The sensory evaluation indicated that CFE 15 showed the best preference in color, taste, texture, flavor, and overall acceptance. Based on these results, 15% should be recommended as a optimum level of CFE to be added for the preparation of yanggeng. And these results suggest that CFE may be a useful ingredient in yanggeng for improvement of the quality.

본 연구에서는 산사추출액을 첨가한 양갱을 제조하여 이화학적 제품특성을 분석하였다. 산사추출액 첨가 양갱의 수분함량은 32.0~32.7%로 대조군과 차이를 나타내지 않았다. 산사추출액 첨가량이 증가할수록 양갱의 pH는 6.8~5.1로 낮아지는 경향을 보이고, 산도는 0.1~0.7%로 증가하였다. 양갱의 색도 측정에서 명도(L)와 황색도(b)는 산사추출액 첨가량이 증가함에 따라 감소한 반면에 적색도(a)는 증가하였다. 조직감 측정에서는 산사추출액 함량이 증가함에 따라 대조군에 비해 경도가 최대 14%까지 증가한다. 관능검사에서 맛, 색, 향, 질감 및 전반적인 기호도 평가에서 산사추출액 15%를 첨가한 양갱이 가장 높은 평가결과를 받았다. 이상의 결과를 통하여 우수한 기능성 소재로 각광을 받고 있는 산사추출액을 기능성 양갱 제조 시 첨가량은 앙금 대비 15%가 가장 적당할 것으로 사료되며, 기능성 가공 식품의 제품개발 및 연구에 산사추출액의 활용도를 높여 가공식품 시장에 도입하였으면 한다.
