Abstract: Aloe vera, a tropical and subtropical plant belonging to the Liliaceae family, contains a transparent mucilaginous jelly known as Aloe vera gel. The drying of osmo air consists of preheating the sample by osmotic dehydration and subjecting it. Osmotic dehydration is incomplete removal by osmotic agent of water from a food product. Initial moisture content of Aloe vera gel was found to be 98.8% and minimum moisture content of dried Aloe vera was found to be 3.01% (wb) after 12hr of osmo-air dehydration treatment. Osmotic dehydration of Aloe vera reduces the initial moisture content of 98.8% to 48.9% at 300 brix sugar concentration whereas reduction from 98.8% to 25.14% was observed in case of 70˚ brix. An intermediate value of reduction to 36.61% wb was observed in case of osmotic treatment at 500 brix. In osmotic treatment at 30o brix the drying rate decreased from 0.2838, 0.1741,0.1233, 0.1138 and 0.0911g/min from 1st to 5th hour, whereas in 70o brix drying rate obtained was found to be highest in the first hour 0.6268 g/min and starts gradually decreasing from 0.6268, 0.2176, 0.1238, 0.0970 and 0.0505 g/min within five hours.
