Effect of moisture content and drying rate on dried aonla shreds during ambient storage

Abstract

The drying behavior of aonla shreds were analyzed using the experimental data of moisture of product at different temperatures viz. 60oC, 70oC and 80oC under cabinet dryer, hot air oven and osmo-air drying. It was found that the drying time of the blanched+ sulphiting aonla shreds samples were less than the controlled and blanched aonla shreds sample at 60oC, 70oC and 80oC respectively. Osmosis as a pretreatment prior to convective air drying was able to decrease drying time. The blanching + sulphiting aonla shred samples with osmotic pre-treatment were more appreciable in comparison to controlled and blanched aonla shred under cabinet tray dryer and hot air oven dryer on the basis of moisture content and drying rate.
