Comparison of several types of cocoa beans relative to fractionated protein components
Protein of seed cotyledons in fruit samples form the clonal collection of CATIE, Turrialba, Costa Rica, were extracted into urea buffer, purified on a column of Sephadex G-25, and separated into seven protein groups on a column of SP-25, cation exchange resin. Among ten samples of Criollo, Trinitario, Nacional, and Forastero cocoa beans, statistically significant (P minor or equal 0.01) differences were found in total and extractable protein contents, in protein group profiles, and in amino acid patterns. Although differences were found among known types of cocoa, they were not considered great enough to suggest the procedures of this investigation as a practical approach to classifying cocoa of unknown genetic origin.
