Time taken for drying of aonla pulp by different methods of dehydration was different. Solar drying of aonla pulp took maximum time for dehydration process whereas minimum time taken for drying was recorded in oven drying. Maximum time taken in drying of aonla pulp in solar drier might be due to regain of moisture during night whereas in oven dried aonla temperature might be maintained throughout the drying period as a result of which there was no regain of moisture and took minimum time for drying. Percent recovery of powder was not affected by various methods of dehydration and there was almost equal percent recovery of powder with minor differences by different methods of drying. This might be due to the reason that various methods of dehydration affected the rate but ultimately the dry matter remained the same which was present in the fruits at initial stage. As a result of which percent recovery was not affected by different methods of drying. Pulp stone ratio is a characteristic of variety and affected by environmental factors. Single variety i.e. Chakaiya was taken for preparation of powder as well as for calculation of pulp stone ratio. So pulp stone ratio had fix value.
