천연식초를 이용하여 분말식초의 제조방법을 개발하고자 부형제의 비율을 달리하여 제조한 분말식초의 품질특성을 평가하여 분말식초의 제조 가능성을 검토하였다. 혼합 피복 물질로 제조된 분말식초의 품질특성을 비교한 결과 -cyclodextrin과 gum arabic이 2.5:7.5의 비율로 제조한 분말식초가 비교적 낮은 수분함량을 나타내었고 산도는 높은 수치를 나타내 식초를 포집하는 능력이 가장 좋은 것으로 나타났다. 또한 이 비율로 제조한 분말식초의 흡
This study was conducted to evaluate the quality and the quantity for manufacturing vinegar powder using spray drying. The -cyclodextrin(CD) and gum arabic(GA) were used as well materials and the mixing ratio of CD and GA was ranged from 10:0 to 0:10. The moisture content of the vinegar powder of 2.5 of CD and 7.5 of GA was lowest among the other mixing ratios. At this proportion, the titratable acidity was highest as it had much included vinegar. The heat stability was not varied much with mixing ratio. However the stability of heat was maintained. Further the water absorption of powder was comparatively low. The manufactured powder vinegar shape was smooth round particles and stable structure by SEM and the particle size was small enough to form capsulation. In sensory evaluation, under these conditions the sourness was highest at 3.5. Therefore, the optimal mixing ratio at 2.5 of CD and 7.5 of GA in wall material was selected.
