Abstract:
Drying is an oldest, efficient and inevitable technology among the food preservation techniques. This technique is significant in reducing of the post harvest loss of the fruits and vegetables. Although, there is strong need for an efficient and cost effective drying technology that reduced the drying time, improve the product quality and enhanced the flexibility in various types of drying products. Beetroot is a second largest sugar crop and has utmost important at commercial level due to presence of several medicinal values. For instance, presence of antioxidant in beetroot helps us in protecting heart and also in preventing cancer. But due to loss of water, sprouting and diseases (bacterial rot, black rot, Rhiizoctonia violacea and Scierotinia scierotiorum) causes of post harvest loss of beetroot in terms of nutritional and market values. the drying of beetroot is, thus, very important to avoid postharvest loss and to preserve the quality and consequently the medicinal values. Fluidized bed drying is very efficient drying method has been used in this study and checked the effect of drying time on outlet air humidity. The feasibility economic of product development was also analyzed in this study. At initial stage of drying outlet air humidity is increasing with respect to drying time, while after some time it deceases by further increase in drying time. The FB dried products had good quality pursuantly texture, flavor and taste.
