Abstract
This research was conducted to investigate the effective methods for browning inhibition on yam (Dioscorea aimadeimo) during dehydration by physical and chemical pretreatments. Moisture, crude protein, crude fiber and N-free extract contents of yam were 81.17%, 1.43%, 0.29% and 15.81%, respectively. Yams were sliced to 0.5 cm thickness and placed to single and poly layer in plastic tray, and then changes of their weights were measured during air dehydration at
건강식품에 대한 기호도가 높아짐에 따라 최근 그 수요가 증가하고 있는 단마의 열풍건조 시의 건조특성과 건조 시 갈변 억제 방법에 관해 조사하였다. 단마의 일반 성분은 수분 81.17%, 조단백질 1.43%, 조섬유 0.29%, 가용성 무질소물이 15.81%었다. 단마를 세척 박피 후 0.5 cm 두께로 세절하여 plastic tray에 박층 및 적층(
