Does microwaving food change the molecular structure?

NO: Very minimal molecular changes happen with microwaving, due to the low energy waves given off. Since they are considered nonionizing waves, chemical changes in the molecules in food do not occur. … NB: Water molecules in microwaved food vibrate rapidly as they absorb the electromagnetic radiation waves.

Does cooking change the molecular structure of food?

Yes, microwaving does change the chemical makeup of food. Any form of cooking does that. Heat initiates a number of chemical reactions, most of which are desirable. Proteins become more digestible and various flavored compounds are produced.

How do microwaves affect molecules?

Microwave ovens work by causing molecules that have two opposing poles to spin rapidly. Because of their polarity, molecules like water will constantly align themselves with a magnetic field they’re subjected to.

What effect does microwave have on food?
