Can someone explain the difference natural and processed cocoa powder in relation to leavening agents.
The pH scale is 0 - 14.
A pH of 7 is neutral.
A pH of 0 - <7 is acidic
A pH of >7 - 14 is alkaline
Baking soda (sodium bicarbonate) is alkaline with a pH of >8.
Baking soda requires a acid AND water to activate.
Baking powder is baking soda (sodium bicarbonate) mixed with an acid. Baking powder will activate with contact with water, then again with heat as the acid(s) used in baking powder will activate the sodium bicarbonate when it comes in contact with water and/or heat.
Natural cocoa powders pH of 5.3-5.8 make it acidic.
Dutch processed cocoa is treated with an alkalized solution to reduce the acidity. The pH levels then move from the acidic side to alkaline side on the pH scale.
- lightly treated cocoa powder pH 6.50 - 7.20
- medium-treated cocoa powder pH 7.21 - 7.60
- heavily treated cocoa powder pH 7.61 and higher
Think of it as opposites attract:
- Natural cocoa powder is acidic; it needs the opposite alkaline. Baking soda is the alkaline
- Dutch processed cocoa powder is alkaline; it needs the opposite acid. Baking powder is the acid
Another thing to keep in mind about cocoa powder is the cocoa butter fat content. Cocoa powder is made from the cocoa bean particles after the cocoa butter has been extracted. Different brands have different amounts of cocoa butter fat in the cocoa powder. The more cocoa butter, the richer the chocolate flavor and better mouthfeel. Cococa powdered is dutched to remove the cocoa powder is alkalized (Dutched) is to remove the sour/bitter taste from the acidity. Since Dutched cocoa powder is preferred by most pastry chefs for its less sour flavor and color, manufacturers tend to produce more high-fat dutched cocoa powder than natural cocoa powder. So it’s also important to know the fat percentage of a cocoa powder when deciding on a cocoa powder for your recipe.
