The results of this study showed that the effects of the roasting air temperature,
IR power and roasting time were significant on moisture content, textural changes and sensory attributes of peanut kernels. According to the result, the combined infrared-hot air roasting significantly reduced roasting time compared to conventional roasting method, therefore
this new roasting method can be designed to a continuous process that is more suitable for industrial-scale application. Overall, combined infrared-hot air roasting method was an effective alternative method
for preparing peanut kernels as snack.
