Conclusions and Recommendations:
Moisture content of fruit powders varied from 6.34% to 9.62% (dry weight basis) .Fat content of Palmyra was found
in the range of 3.69 to 3.95% and bael was not recorded a significant level of fat content after dehydration. Higher
concentration of β –Carotene and total phenolic content and maximum retention of antioxidant properties were
recorded in vacuum dried samples both in bael and Palmyra fruit powders and it significantly different (α= 0.05) from
other treatments. Therefore vacuum drying can be recommended as the most effective drying method to protect
chemical characteristics and retention of antioxidant in fruit powders.
