Caramelization vs Maillard: What's the difference?

Quick Takeaway: Caramelization is sugar breaking down, while Maillard requires both sugar AND protein. They happen at different temperatures and create different flavors.

Caramelization: Sugar Alone

Caramelization occurs when sugars break down under heat, creating: - Temperature: Starts around 320°F (160°C) - Requirements: Only sugar needed (no protein) - Flavors: Sweet, nutty, buttery notes - Examples: Caramel sauce, toasted marshmallows, roasted vegetables

Maillard Reaction: Sugar + Protein

The Maillard reaction requires both amino acids and reducing sugars: - Temperature: Starts around 285°F (140°C) - Requirements: Both sugar AND protein/amino acids - Flavors: Savory, meaty, complex umami notes - Examples: Seared steak, roasted coffee, toasted bread

Why Both Matter

Many foods undergo both reactions simultaneously: - Bread crust: Maillard (flour proteins + sugars) + Caramelization (surface sugars) - Roasted vegetables: Caramelization (natural sugars) + Maillard (amino acids from proteins) - Coffee beans: Both reactions create the complex flavor profile

Practical Applications

- Low heat cooking: Primarily caramelization (sweet flavors) - High heat cooking: Both reactions (complex, savory flavors) - Acidic environments: Can inhibit Maillard but not caramelization
