To assess the quality of commercial Sujongkwa, we compared physicochemical and sensory characteristics of commerial 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 characteristic (7-point scoring test, 18 experienced panel members). Separately, we asessed the opinion of food and nutrition specialists aout 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 analzed using SPSS Program for Window (mean, ANOVA, χ²).
