How Are Cocoa Beans Processed Into Three Core Products

This is the foundation for all further processing. Fermented and dried cocoa beans are sent to factories for:

1. Roasting: Beans are roasted at 120-150°C to develop rich chocolate flavor and make the shells brittle.
2. Winnowing: Beans are cracked, and air is used to blow away the lighter shells, leaving pure "cocoa nibs".
3. Grinding: The cocoa nibs are ground by heavy mills. Friction generates heat, melting the natural fat (cocoa butter, about 55% of the nib).

• Result: A hot, flowing brown paste is produced. This is "cocoa mass" (or cocoa liquor). It solidifies into hard blocks when cooled.

Cocoa Mass = The natural mixture of cocoa solids + cocoa butter. It is the base ingredient for all chocolate products, determining the fundamental flavor and color.

This is the critical separation step, using powerful hydraulic presses on the cocoa mass.

1. Pressing: Warm, soft cocoa mass is placed into a press under immense pressure.
2. Separation:

• The golden liquid that flows out: This is pure "cocoa butter". It solidifies at room temperature, is ivory or pale yellow, and has a pleasant chocolate aroma without strong bitterness or acidity.
• The solid cake left in the press: This is the "cocoa cake". It still contains about 10%-24% residual cocoa butter, with the remainder being dry cocoa solid particles.

This is the final step of pulverizing and refining.

1. Milling: The hard cocoa cake is crushed by hammer or roller mills.
2. Cooling & Sifting: The crushed powder is cooled and passed through fine sieves to ensure uniform, fine particles.
3. Types: Based on the alkalization of the cake and fat content, different cocoa powders are produced:

• By Treatment:

Natural Cocoa Powder: Not alkalized; lighter color (reddish-brown), acidic and tart flavor.

Dutch-Process/Alkalized Cocoa Powder: Treated with an alkali; darker color (deep brown), milder, smoother flavor, better solubility. This is now the mainstream type.

• By Fat Content:

High-Fat Cocoa Powder (≥20%)

Medium-Fat Cocoa Powder (10%-20%)

Low-Fat Cocoa Powder (<10%)

Cocoa Powder = Cocoa cake in powdered form. It is the concentrated flavor of the cocoa bean, widely used in baking, beverages, desserts, and the food industry.
