Mars, the giant chocolate maker, is planning on solving
humanity’s cocoa crisis (yes, there is one) by joining IBM and the U.S.
Department of Agriculture in mapping the DNA of the cacao tree. The purpose of
this is to improve cocoa crops and thus the quality of chocolate.
The cacao tree originates in the tropical regions of the
Americas, but cocoa plantations can be found in Africa and Asia as well. West
Africa is now the number one producer of cocoa in the world (70 percent).
Cocoa has played a major role in the history of ancient
civilizations and had multiple uses, from food to medicines and in ceremonies.
Moreover, some civilizations even used cocoa as currency system. Cocoa means in
the Mayan language “food of the gods.”
Is takes several years for a tree to start producing cacao pods,
which contain several hundred seeds. These are mainly used in the manufacture
of chocolate and chocolate drinks.
There are several distinct groups of cacao beans, some less
bitter and more aromatic than others. These differences in flavor, together
with the way the chocolate is processed, can influence the way the final
product tastes like.
World’s cocoa production, mostly grown by small farmholders
(over 90 percent), has been affected in recent years by climate change and
pests, which inflicted serious economic damages and decreased production.
This is where Mars decided to step in and protect the future
of the $5 billion market. By sequencing the cocoa genome, the chocolate
producer is hoping to improve the breeding of cacao plants, as well as the
quality of cocoa and thus the quality of chocolate.
In order to obtain long term results and to increase the
plants’ resistances to disease and pest, as well as climate change, researchers
have been working on a five-year project to discover the secrets of the cocoa
genome.
“Sequencing the genomes of agriculture crops is a critical
step if we want to better understand and improve a crop,” said Judy St. John
from the U.S. Department of Agriculture, as quoted by Reuters.
In recent years, scientists have analyzed the genome of
several other plants, such as rice or corn, but cocoa has had little attention
so far.
The end of the five-year process of figuring out the cocoa
genome will be in fact the beginning of another process, that of generating raw
cocoa DNA.
Once the useful genes have been identified, scientists will
be able to accelerate the breeding process, improve cocoa crops and obtain
higher yields.
Cocoa is not only the key ingredient to the chocolate
production, but it also exhibits a series of health benefits.
According to the International Cocoa Organization, chocolate
is one of the largest contributors of dietary coppers in the United States (dietary
copper is believed to contribute to the prevention of heart disease).
More than that, chocolate is a great source of vitamins, as
cocoa contains anything from vitamin E to vitamin B complex. Cocoa butter also
contains vitamins A and E.
Some scientists attribute cocoa and chocolate even more
health benefits, such as the ability to reduce the risk of certain types of
cancer.
