For this purpose, the taro foams with and without ultrasonic pretreatment (35 kHz, 80°C for 25 min) were dried in a convective oven (70°C, 20% ventilation rate) and microwave oven (460 W). The UP resulted in a higher drying rate, diffusion coefficient, moisture content, Hausner ratio (HR), and wettability time, and a lower drying time compared to the nontreated samples. Combined CHAD and MOD‐assisted FMD improved the disadvantages of the CHAD method for example: long drying time (decreased around 63.33% for CHAD and 59.16% for UP + CHAD), low drying and diffusion rates, high moisture content, low brightness (L*) values...
