Quality
There are two types of cocoa beans.
More than 90% of cocoa produced annually can be considered as bulk (or
basic) cocoa. Bulk cocoas mostly come from Africa and Brazil, mainly
of the forastero variety. Fine and flavor cocoas have distinctive aroma
and flavor characteristics, sought after by chocolate manufacturers.
They represent only 5% of world cocoa production.
The International Cocoa Standards
require cocoa of merchantable quality to be fermented, thoroughly dry,
free from smoky beans, free from abnormal or foreign odors and free
from any evidence of adulteration. It must be reasonably free from living
insects, broken beans, fragments and pieces of shell and foreign matter
and reasonably uniform in size.
Throughout the world the standards
against which all cocoa is measured are those of Ghana cocoa. Cocoa
is graded on the basis of the count of defective beans in the cut test.
Defective beans should not exceed the following limits:
Grade I
v Mouldy beans, maximum 3% by count;
v Slaty beans, maximum 3% by count;
v Insect-damaged, germinated or flat beans, total maximum 3% by count.
Grade II
v Mouldy beans, maximum 4% by count;
v Slaty beans, maximum 8% by count;
v Insect-damaged, germinated or flat beans, total maximum 6% by count.
