기능성 음료(CJ(주) 팻다운)의 유통기간을 설정하기 위해 12주 동안 저장하면서 이화학적 및 관능적 특성을 조사하였다. 진공도, 당도, pH 및 산도는 저장기간 동안 거의 변화를 나타내지 않았으며, 총균 또한 검출되지 않아 저장기간 동안 미생물학적으로도 안전한 것으로 나타났다. 관능검사의 전반적인 기호도와 이화학적 특성을 회귀분석한 결과 색도의 b (yellowness)값이 0.9504으로 가장 높은 상관계수를 나타내어 b값을 기능성 음료의 품

Shelf-life of functional beverage for the purpose of body fat reduction during storage was estimated at different temperatures. To estimate quality change of functional beverage, vacuum gauge, sugar concentration pit acidify, Hunter's color value, browning color intensity, total cell count and sensory evaluation were measured periodically. Vacuum gauge, sugar concentration pH and acidity were little changed and total cell count was not detected. By using the correlation coefficient between sensory evaluation and physicochemical properties, b-value was chosen for quality index of functional beverage. for shelf-life were in the range of . When sensory evaluation was 2.5 at , storage period was 6.83 weeks. And shelf-life calculated by were 73.89, 34.21 and 13.21 weeks in , respectively.
