Abstract

To assess the quality of commercial Sujongkwa, we compared physicochemical and sensory characteristics of commercial Sujongkwa with home-made one. Two different brands of Sujongkwa and home-made one were analyzed for physicochemical (sugar content, pH, acidity, color, viscosity, transparency) and sensory characteristics (7-point scoring test, 15 experienced panel members). Separately, we assessed the opinion of food and nutrition specialists about the commercial Sujongkwa. Questionnaires were hand delivered to 530 subjects consisted of university students and faculties of Department of Food and Nutrition at 8 cities (Seoul, Incheon, Yongin, Daejon, Chungju, Daegu, Kwangju, Busan) in Korea and the complete data of 328 subjects were statistically analyzed using SPSS Propam for Window (mean, ANOVA, $\chi$$^2$). The questionnaires were consisted of sociodemographics, frequency and occasion of purchasing, opinion of quality and improvement points. Both commercial Sujongkwas were lower in sugar content, transparency, color(L and b value) and viscosity, and commercial brand B was higher in pH and color a value than home-made one. Also, among sensory characteristics, over-all preference and color for brand B were significantly higher than those for brand A and home-made one (p<0.05). Especially, the scores of over-all preference were 1.9 for brand A, 5.7 for brand B, and 4.9 for home-made Sujongkwa. Points to be improved for commercial Sujongkwa were in order of sweetness (33.0%), pungency (24.2%), dried persimmon (19.1%).

시판 수정과 2종의 이화학적, 관능적 품질특성을 전통 수정과와 비교하고 전국의 식품영양학과 학생 및 교수 382명을 대상으로 수정과의 품질에 대한 설문조사를 실시한 결과는 다음과 같다. 시판 수정과는 2종은 전통 수정과에 비해 당도, 투명도, 점도, L 및 b값이 낮았다. 그러나 시판 수정과 B는 전통 수정과에 비해 pH가 높았다. 시판 수정과의 관능적 특성은 향, 맛, 감미 정도, 매운 정도, 부재료의 양면에서 전통 수정과에 비해 유의적으로 낮은 점수를 나타내었다. 그러나, 시판 수정과 B는 색상과 전반적인 기호도면에서 전통 수정과에 비해 유의적으로 높은 점수를 나타내었다. 전공자들을 대상으로 한 설문조사 결과, 시판 수정과는 전통 수정과와 '동일하지 않다'가 50.1%로 많았으며 시판 수정과에서 개선할 점으로는 '단 정도' 33.0%, '매운 정도' 24.2%, '곶감 함유' 19.1%이었다. 이상의 결과를 바탕으로 기업체에서는 제조회사별로 바람직한 면은 잘 살리고 개선해야 할 점들은 보완하여 가정에서 만들어 왔던 수정과의 품질에 더욱 가깝게 제조하려는 노력이 있어야 할 것으로 생각된다.
