Abstract
The objectives of this study are to establish efficient pretreatment concentration and rehydration process for the production of the high quality of freeze-dried Mook, a traditional gel food in Korea, as an instant food. Effect of immersion in sucrose solution as pretreatment before freeze-drying on the rehydration efficiency and quality characteristics was studied. The rehydration efficiency of non-treated Mook was the highest. The rehydration efficiency increased as the concentration of sucrose increased. The texture of rehydrated Mook treated in sucrose solution was decreased with increase in rehydration temperature. The Mook treated at 60% sucrose solution was somewhat similar to the market selling Mook in the quality and the treatment prevented color and texture degradation.
동결건조묵을 인스탄트화 하기 위하여 당용액으로 전처리한 것과 무처리 한 것을 동결건조하여 건조물의 재수화특성과 품질특성을 비교해 보았다. 당용액(sucrose)에 침지하여 전처리한 묵의 재수화 효율은 무처리가 가장 높았고 당침지의 경우는 60%, 40%, 20% 순으로 낮아졌으며 온도의 영향은 당용액의 농도와는 관계없이
