Winnowing cocoa is a process in the production of chocolate that involves separating the outer shell, or husk, from the cocoa beans. The cocoa beans are the seeds found inside the pods of the cacao tree. After the beans are harvested and fermented, they are dried and then roasted.
Winnowing is the step that follows roasting. During roasting, the outer husk becomes brittle, making it easier to separate from the inner nib, which is the part used to make chocolate. Winnowing is typically done with specialized equipment such as winnowers or cocoa cracker and fanners.
Here's a general overview of the winnowing process:
-
Roasting: The cocoa beans are roasted to develop flavor and aroma, and this also makes it easier to separate the husk from the nib.
-
Cracking: The roasted beans are then cracked open to reveal the nib inside. The nib is the part of the cocoa bean that contains the cocoa solids and cocoa butter.
-
Winnowing: The cracked beans are subjected to air currents, which help blow away the lighter husk, leaving behind the heavier cocoa nibs. This separation is typically done using winnowing machines that have fans to create airflow.
-
Separation: The winnowed nibs are then collected, and the remaining husk is discarded.
After winnowing, the cocoa nibs can be ground into a paste called chocolate liquor, which can then be further processed to separate cocoa solids from cocoa butter. The cocoa solids and butter can be used in various proportions to produce several types of chocolate products. The winnowing process is crucial for obtaining high-quality cocoa nibs for chocolate production.
