Which of the following statements is not true for microwave processing?

Correct option is D

• In microwave heating, water molecules and other polar molecules rapidly oscillate under an alternating electromagnetic field, generating heat through dipole polarization.
• Dissolved salts also contribute by ionic conduction, where ions oscillate and produce heat.
• Microwaves indeed belong to the electromagnetic spectrum, typically around 2450 MHz for food processing.
• Dry foods, however, do not heat efficiently because they lack sufficient water molecules to absorb microwave energy.
• Wet foods heat more efficiently due to their high water content, making option (d) the incorrect statement.
