Abstract

This study was conducted to improve the quality properties of cream soup in accordance with the added amount of sweet pumpkin and Chungdong pumpkin, roux and chicken stock. As the amount of pumpkin was increased, red (a-value) and yellow (b-value) colors increased but its lightness (L-value) remarkably decreased. Also, there was a significant differences in viscosity, color, appearance and overall preference of sensory evaluation. In pumpkin 150 g (37.5%) added, the degree of total preference was high. As the added amount of roux was increased, red and yellow colors decreased by small margin and there was a significant differences in color, flavor, appearance and overall preference of sensory test. At adding roux of 5 mL (1.5%) showed the highest preference. With the adding chicken stock increase the lightness, red and yellow color decreased. It was found by sensory evaluation that there were significant differences in viscosity, color, flavor, appearance and overall preference. At adding chicken stock 150 mL (37.5%) and milk of 50 mL (12.5%) showed the high score in flavor, appearance and total preference.

본 연구는 각종 영양적, 식품 기능적 특성이 우수한 청동호박과 단호박을 이용한 크림수프를 제조하기 위해 재료의 첨가량에 따른 품질 특성을 비교하여 최적의 크림수프의 제조 조건을 산출하기 위한 것이다. 그 결과 호박을 이용한 크림수프의 제조 시 주재료인 호박과 화이트 루의 첨가량에 따라 품질 특성에 있어 전반적인 유의성이 평가되어, 호박의 첨가량은 색상과 외관에 대한 선호도에 영향을 주었고, 화이트 루는 점도와 맛에 영향을 준 것으로 평가되었다. 호박은 첨가량이 증가할수록 명도는 현저하게 감소하였고 적색도와 황색도는 증가하였다. 점도, 색상, 외관, 전체 선호도에서 유의적인 차이를 나타냈고 첨가량 38%의 경우에 가장 높은 선호도를 나타내었다. 루 첨가량이 증가할수록 명도는 증가하고 적색도와 황색도는 소폭으로 감소하였다. 색상, 맛, 외관, 전체 선호도에서 유의적인 차이를 나타냈고 첨가량 1.5%인 경우에 가장 높은 선호도를 나타내었다. 닭 육수의 첨가량이 증가하고 우유의 첨가량이 감소할수록 명도는 전반적으로 증가하고 적색도와 황색도는 감소하였다. 점도, 색상, 맛, 외관, 전체 선호도에서 유의적인 차이를 나타냈고 닭 육수 37.5% : 우유 12.5%의 첨가가 가장 높은 선호도를 나타내었다. 점도 특성으로 호박 첨가량이 증가함에 따라 점도가 큰 폭으로 증가하였으며 닭 육수도 점도 증가의 요인이 되었다. 또한 화이트 루의 첨가량에 비례하여 점도가 전반적으로 증가하였다. 온도 증가에 따라 점도도 전반적으로 증가하여 온도차에 따라 큰 변화를 나타내었다. 단호박을 첨가하여 제조한 크림수프의 최적 품질 조건으로 호박 첨가량은 단호박과 청동호박을 1 : 1의 비율로 하여 37.5% 첨가하고, 닭 육수는 호박과 동량을 첨가한 후 닭 육수의 30%에 해당하는 양의 우유를 부가했을 때 색도, 점도와 전반적인 기호성이 높았다. 또한 화이트 루는 1.5% 첨가 시 최적 품질의 크림수프 제조를 위한 배합비율로 산출되었다.
