단호박 가루 첨가량을 달리한 호상 요구르트를 개발하여 요구르트의 품질특성을 비교하였다. 단호박 가루의 첨가량 0%, 0.5%, 1%, 2%, 3%로 첨가하여 요구르트를 제조해 색도(명도, 적색도, 황색도), 점도, pH, 산도, 관능검사(색, 향, 맛, 전반적 기호도)를 측정하고 1일, 5일, 10일, 15일등 5일차 간격으로 저장성 실험을 하였다. 색도에서는 저장기간별 단호박 첨가량이 증가할수록 L값은 감소하였으나 a,b값은 증가하였다(p2%>
Sweet Pumpkin (Cucurbita maxima) is rich in minerals, vitamins, and dietary fibers and has less fat. It is thus effective for dieting and for preventing constipation. Sweet Pumpkin contains vitamin A, particularly beta-carotene, which is turned into retinol in the body and helps protect the vision. It is currently on the spotlight as a vision care, anticancer, and diet food, among others, but because it is hard to find yogurt made of Sweet Pumpkin, in this study, Sweet Pumpkin powder was added to yogurt for promotion as a new health food. Yogurt was made with 0, 0.5, 1, 2, and 3% Sweet Pumpkin powder, and the color properties (brightness, redness, and yellowness), viscosity, pH, and acidity were measured through a sensory test (color, flavor, taste, overall acceptability). The storage stability at five-day intervals for one day, five days, ten days, 15 days, etc. was also experimented on. For the color properties, the greater the amount of Sweet Pumpkin powder added, the greater the decrease in the lightness (L) value, but the redness (a) and yellowness (b) values increased (p2%.3%>0%>0.5%. The study results indicate that the addition of 1% Sweet Pumpkin powder is most suitable for manufacturing Sweet Pumpkin yogurt.
