Cocoa beans.
Dutch processing, or "Dutching," is an alkalizing method used to treat cocoa products. By applying a food-grade alkali solutionāmost commonly potassium carbonateāthe process partially neutralizes the natural acetic acid found in cocoa beans.1
This treatment significantly alters the characteristics of the cocoa powder:
- Colour: The process darkens the colour of the powder.1
- Flavour: It mellows the flavour, contrasting with the "pleasantly sharp" taste of natural-process cocoa, which remains acidic with a pH of 5.2ā5.8.12
By adjusting the pH, sometimes as high as 8.0, Dutching fundamentally changes the taste profile of the final product.1
