  • Microwave Drying - an overview

    Microwave (MW) drying is a technique based on electromagnetic waves that generate heat directly inside the product ( Lenaerts et al., 2018 ). MW radiation is a part of the electromagnetic spectrum ranging from 300 MHz to 300 GHz. As MW produces heat inside the food product, it causes rapid internal heating.
