Gelgoog Cocoa Alkalization Technology(Dutch-Process Cocoa Solution)

Gelgoog Cocoa Alkalization Technology, also known as dutched cocoa powder, is a value-added process in cocoa processing to produce alkalized cocoa mass or powder. The alkalization process can be applied to various cocoa products such as whole beans, nibs (before roasting and grinding), liquor (prior to pressing), or the powder, although it is most often the nibs that are alkalized.

Cocoa alkalization technology

Key Features of cocoa alkalization technology:
Precise pH Control – Adjustable from 6.5 to 8.5 to achieve light brown to deep red/black color.
Uniform Alkali Distribution – Paddle or screw-type reactor ensures even mixing of alkali solution (potassium carbonate, sodium carbonate, etc.) with cocoa nibs or liquor.
Temperature & Moisture Management – Integrated heating and drying stages for optimal alkalization efficiency.
Easy Cleaning & Maintenance – Stainless steel construction (SS304/SS316), CIP-friendly design.

Why cocoa alkalization?

Reasons for alkalizing cocoa include:
1. Reducing the acidity of natural cocoa (pH is raised from 5.2–5.6 to almost neutral values at 6.8–7.5)
2. Reducing sourness
3. Producing intense flavors and darker colors
4. Increase solubility and dispersibility of cocoa in water (key in chocolate beverages)
