The effect of microwave-assisted drying (MAD) and deep-fat frying conditions on moisture and oil contents, hardness, chewiness, and colour (L*, a*, and b*) attributes of orange-flesh-sweet-potato (OFSP) chips were studied. A response surface methodology based on Box–Behnken design was used to optimize the effect of weight loss (10 – 20%) during MAD, frying temperature (150 – 170 °C), and frying time (1 – 3 min) on moisture, oil contents, hardness, chewiness, and colour of the chips. Models were generated showing the relationship between independent and response variables. The process variables had significant effects on the investigated responses. Frying temperature had a significant (p |
