천연식초를 이용하여 분말식초의 제조방법을 개발하고 아울러 분말식초의 품질특성 및 제조공정을 평가하여 분말식초의 제조 가능성을 검토하고자 하였다. 식초와 포접물질을 혼합한 포접물의 최적 농도는 피복물질의 양이 많을수록 흡습이 잘 되지 않고 열에도 안정함을 보였으나 포접물질의 양이 증가할수록 포접물질의 맛이 강하게 나타나 식초의 고유한 관능적인 특성이 떨어지므로 포접물의 농도를 30。bx 로 결정하였다. 분무건조공정을 최적화하기 위해 인입온도와 fl

This study was conducted to develop processing method for vinegar powder from natural vinegar for encapsulation applications. To optimize the spray drying process, experiment was designed by central composition method to find optimal conditions for manufacturing vinegar powder. The acidity, water absorption, solid content and heat stability of vinegar powder were selected as response variables. The optimal concentration of inclusion complex which was made with vinegar and -cyclodextrin was determined on 30。bx. On increasing the concentration of -cyclodextrin as a wall material, the quality of the vinegar was decreased. The optimum conditions of spray drying process for manufacturing vinegar powder were 188∼192 and 500∼600 Lh -1/ as inlet temperature and flow rate, respectively.
