Alkalized cocoa
Definition
What it is
Alkalized / Dutch-process cocoa: treated with potassium carbonate to reduce bitterness; this process destroys 60–90% of the beneficial flavanol content that makes dark chocolate heart-healthy.

Explainer
In plain language
Alkalized cocoa, often called Dutch-process cocoa, is cocoa that has been treated with an alkaline solution such as potassium carbonate. The treatment neutralizes some of the natural acidity, which makes the cocoa milder, less bitter, and darker in color. It is a processing step, not an added chemical you eat in large amounts, and it is common in baking cocoa and many chocolate products.
Assessment
Why it is flagged
The main reason Clear Label flags alkalized cocoa is not safety but nutritional loss. Cocoa naturally contains flavanols, plant compounds that some studies have associated with cardiovascular benefits, and alkalization reduces their levels substantially. A 2008 study published in the Journal of Agricultural and Food Chemistry measured large drops in flavanol content across different degrees of alkali processing. This does not make the cocoa harmful; it means the marketing image of dark chocolate as a flavanol source may not hold for heavily alkalized products. If you eat cocoa partly for those compounds, the processing method is worth knowing.

- Some chocolate protein powders and drink mixes
Practical
Reading the label
Look for the phrases 'processed with alkali', 'cocoa processed with alkali', 'Dutch-process', or 'alkalized cocoa' in the ingredient list. Natural cocoa that has not been alkalized usually says just 'cocoa' or 'cocoa powder'.
Alternatives
If you want to avoid it
Some people who want more of the natural flavanols choose natural, non-alkalized cocoa powder, which tends to taste sharper and more acidic. Both types work in most recipes, though the acidity can affect how baking soda and baking powder behave.
FAQ
Common questions
Is Dutch-process cocoa bad for you?
There is no evidence that alkalized cocoa is harmful at normal intakes. The flag is about reduced flavanol content, not safety, so it matters mainly if you eat cocoa specifically for those plant compounds.
What is the difference between natural and alkalized cocoa?
Natural cocoa is untreated and more acidic, while alkalized cocoa is treated to reduce acidity and bitterness. The treatment also lowers flavanol levels and darkens the color.
Can I tell from a chocolate bar whether the cocoa was alkalized?
Not always. Bars often just list 'cocoa' or 'cocoa mass' without noting processing, so the 'processed with alkali' phrasing is more common on cocoa powders and mixes.
