Description of Chocolate
Chocolate is made from cocoa beans
found on the cacao tree.
•The cacao tree was first discovered in
the South American rainforest.

The three main ingredients in chocolate
are chocolate liquor, cocoa powder, and
cocoa butter.
Different kinds of chocolate use varying
amounts of these 3 ingredients.
About the Cacao Tree
How Chocolate is Made
•The cacao tree is cultivated in many
countries, but today the leading suppliers
are
Ivory
Coast, Ghana, Indonesia, Nigeria, Brazil, Came
roon, Ecuador, Dominican Republic and Papua
New Guinea.
History of Chocolate
How Chocolate is Made
 Dates back to about 1,500 years ago.
 First found in Mayan and Aztec Civilizations.
• Mayans used cacao beans to create a
cold, unsweetened, spicy chocolate beverage. This was
the first form of chocolate.
• Aztecs came across cacao beans through trade. They
named the spicy drink xocolatl (bitter water).
• Cacao beans played important roles in both Mayan and
Aztec Civilizations.
History of Chocolate
How Chocolate is Made
•The cocoa bean was introduced to Spain in the 16th
century.
•The chocolate drink was first brought to Europe by Spanish
conquistador, Hernan Cortes.
The drink was sweetened to match European tastes.
The drink was also prescribed to people for depression and used in love
and death potions.

•In the late 18th century French and Dutch processors
experimented with chocolate liquid.
The first chocolate bar was made in Switzerland in 1819, and in 1875 the
milk chocolate was invented.
Harvesting Cocoa & Cocoa processing

How Chocolate is Made

Step #1: Plucking and opening the Pods
Cocoa beans grow in pods that sprout off of the trunk and branches of
cocoa trees.
The pods start out green and turn orange when they are ripe.
After the cocoa pods are collected into baskets, they are split open
and the cocoa beans are removed
Fresh cocoa beans are not brown at all, they do not taste at all like
the sweet chocolate they will eventually produce.
Step #2: Fermenting the cocoa seeds
Now the beans undergo the fermentation
processing.
 They are either placed in
large, shallow, heated trays or covered with
large banana leaves.
 If the climate is right, they may be simply
heated by the sun.
 Workers come along periodically and stir
them up so that all of the beans come out
equally fermented.
 During fermentation is when the beans
turn brown. This process may take five or
eight days.
Step #3: Drying the cocoa seeds
After fermentation, the cocoa seeds
must be dried before they can be
scooped into sacks and shipped to
chocolate manufacturers.
 Farmers simply spread the fermented
seeds on trays and leave them in the
sun to dry.

 The drying process usually takes
about a week and results in seeds that
are about half of their original weight.
The dried and roasted Cocoa beans
Manufacturing Chocolate
Step #1: Roasting and Winnowing the Cocoa
The first thing that chocolate manufacturers
do with cocoa beans is roast them(develops
the colour and flavour).
 The outer shell of the beans is removed,
and the inner cocoa bean meat is broken into
small pieces called "cocoa nibs.“
The roasting process makes the shells of
the cocoa brittle, and cocoa nibs pass
through a series of sieves, which strain and
sort the nibs according to size in a process
called "winnowing".
Step #2: Grinding the Cocoa Nibs
Grinding is the process by which cocoa
nibs are ground into " cocoa liquor“.

 The grinding process generates heat
and the dry granular consistency of the
cocoa nib is then turned into a liquid as the
high amount of fat contained in the nib
melts.
 The cocoa liquor is mixed with cocoa
butter and sugar. In the case of milk
chocolate, fresh, sweetened condensed or
roller-dry low-heat powdered whole milk is
added.
Step #3: Blending Cocoa liquor and
molding Chocolate
After the mixing
process, the blend is further
refined to bring the particle
size of the added milk and
sugar down to the desired
fineness.
 The Cocoa powder or
'mass' is blended back with
the butter and liquor in
varying quantities to make
different types of chocolate.
Chocolate Facts

Potential Health Benefits
Chocolate may be good for the heart.
 Chocolate contains chemicals like those found in red
wine and green tea.
 Helps improve circulation
 Helps cut down blood pressure

 Chocolate contains flavanols.
 Helps in preventing the oxidations of “bad” cholesterol, which
reduces the stickiness of blood platelets and improve blood
vessel elasticity.

Theobromine, found in chocolate, was found to
treat coughs better than codeine.

World's most expensive chocolate
Le Chocolate Box

Price: $1.5 million
Generally women are overwhelmed with two types of gifts, one is
