Maillard Reaction vs Caramelization: What’s the Difference?

The difference at a glance

Maillard reaction requires both proteins and sugars to create savory, browned flavors. Caramelization focuses strictly on the thermal decomposition of sugars alone.

Example sentences are illustrative learning examples, not verified quotations.
