Abstract

The response surface methodology was performed by central composite design for moisture content, titratable acidity, hunter's color value and organoleptic properties based on drying temperature and time of Citrus, to apply basic data to preparation of dried Citrus. Moisture content, b value and organoleptic color were affected by drying temperature ; That decreased with increase of drying temperature. Titratable acidity was affected by drying time. Organoleptic flavor and taste were affected by drying temperature and time. The optimum drying conditons for organoleptic taste were 67.56$^{\circ}C$ in drying temperature and 8.06 hr in drying time.

건조감귤을 제조하기 위한 기초자료로 활용하고자 건조온도 및 건조시간에 따른 수분함량, 적정산도, 기계적 색도 및 관능적 특성을 중심합성실험계획으로 반응표면분석을 실시하였다. 수분함량, 황색도 및 관능적인 색상의 경우 건조온도에 영향을 많이 받으며, 건조온도가 증가할수록 감소하는 것으로 나타났다. 적정산도의 경우 건조시간에 영향을 많이 받는 것으로 나타났으며, 관능적인 향 및 맛의 경우 건조온도 및 건조시간에 영향을 받는 것으로 나타났다. 관능적인 맛의 경우 건조온도 67.56$^{\circ}C$ 및 건조시간 8.06 hr으로 건조할 때 가장 우수한 것으로 나타났다.
