PG - 625-635 LID - 10.1007/s13197-021-05050-3 [doi] AB - Papad is a crunchy wafer-like snack food consumed all over India and other Asian countries. Traditionally, sun-drying requires more drying time and reduces less moisture from papad, which absorbs more oil during frying. The current study was carried out using microwave-assisted hot air drying (MAHD) to reduce fried papad oil content. Box-Behnken design (BBD) was selected to perform 17 trials for drying of papad using MAHD along with different power levels (300, 600, and 900 W), exposure times (30, 60, and 90 s) and hot air temperatures (40, 50 and 60 degrees C). The fried papad characteristics were evaluated in terms of oil content, oil uptake ratio, porosity, expansion and texture using standard procedures. MAHD helped reduce higher than 30% of fried papad oil content compared to the traditional method. Scanning electron microscope (SEM) confirmed that the MAHD papad has fewer pore structures than sun dried-fried papad. Using response surface methodology (RSM), the optimized parameters of MAHD was found to be 653 W power level with an exposure time of 56 s at 43 degrees C of drying temperature, which reduced oil content (7.90 +/- 0.02%), oil uptake ratio (1.50 +/- 0.03), porosity (16.33 +/- 0.29%) and expansion (7.97 +/- 0.02%) of fried papad.
