How chocolates are manufactured?
Making chocolates is a long process. It starts from harvesting
cocoa and finishes with the drying of chocolate. The process
begins with,
Fermentation: After collecting the cocoa beans and surrounding
pulp from the cacao tree the fermentation process starts. These
seeds and pulp are placed either in boxes or banana leaves. It
takes 5-6 days to form alcohol from the sugar of the beans. In
the mean time the surrounding pulp become liquid and drain out.
During the fermentation process the seeds germinate and are
killed in high temperature. The beans turn into brown color and
look like our familiar cocoa seeds.
After the fermentation process the beans are dried and water
content is lowered from 60% to 7%.
Roasting: After drying the roasting process takes place. The
required temperature for roasting is 210F. For 10 to 115 minutes
the beans are roasted. Roasting develops the aroma and flavor.
Constant monitoring is needed during the process. Over roasting
can make beans useless.
Winnowing: In this process the shells of the beans are removed.
Grinding: Ready beans are grinded in two phases. In the first
phase large stones are used for grinding. In this process a
liquid pulp is produced. This is called cocoa liquor. Then sugar
is added into the pulp. The average size of the particles would
be around 100 microns at this stage. Then starts the second
phase of finer grinding and this grinding turns the particles
into 18 microns in size.
Conching: At the temperature of 180F the pulp is stirred and
mixed. In this process the sugar and cocoa particles collide
together and this makes the pulp smoother. The conching process
can be for few hours to 1 day. In fact, the longer you conch
better chocolate you make. In the process extra cocoa butter can
be added. To stabilize the chocolate soy lecithin is added. And
at the last stage vanilla is added.
After the process the pulp is taken out of the concher and
poured into a suitable pot. When it cools down the chocolate is
ready to eat.
