초록

오미자 열매 추출물의 첨가량을 0-50%로 달리하여 식혜를 제조한 후 물리화학적 및 관능적 품질특성을 측정하고 각 특성사이의 상관관계를 살펴보았다. 추출물의 첨가량이 증가함에 따라 식혜의 pH는 유의적으로 감소한 반면 가용성 고형분 함량 및 적색도 ($a^*$값)는 증가하였다(p<0.05). 한편, 밝기를 나타내는 $L^*$값과 황색도를 나타내는 $b^*$값은 추출물의 첨가량과 직접적인 관계를 나타나지 않았다. 관능적 품질특성 중 색, 신맛, 단맛은 추출물의 첨가량과 유의적인 관계를 나타내었다(p<0.05). 상관분석 결과 추출물의 첨가량은 $L^*$값과 $a^*$값을 제외한 모든 물리적 및 관능품질 특성과 유의적인 관계를 나타내었다. 소비자 기호도검사에 의하면 10% 오미자 열매 추출물을 첨가한 식혜의 전체적인 기호도가 다른 시료군에 비해 유의적으로 높음을 알 수 있었다(p<0.05).

The effects of incorporating hot water extract of Schisandra chinensis fruit on the physicochemical and sensory properties of Sikhe were investigated. The extract was incorporated at 5 levels (0, 10, 20, 30, 40, and 50%, v/v) by replacing equivalent amount of distilled water. The pH decreased while the soluble solids content increased significantly with the increase in the extract replacement (p<0.05). Redness ($a^*$-value) increased significantly as the extract concentration increased (p<0.05); on the other hand, lightness ($L^*$-value) and yellowness ($b^*$-value) did not show any direct relationships with the extract replacement. Color, sour taste, and sweet taste except for Sikhe flavor were distinctively classified by the sensory analyses (p<0.05). Correlation analysis indicated that level of extract incorporation was well-correlated with all the physicochemical and sensory properties studied except for $L^*$- and $a^*-$ value. Finally, the consumer test based on Friedman-type statistic, suggested that 10% incorporation of the hot water extract of Omija fruit was recommended for making Sikhe.
