Title: A cor verde do endosperma do café
Title Alternative: On the green color of coffee endosperm

Abstract: A comparison was made between the green seeded Mundo Novo and the yellow seeded Cera cultivars of Coffea arabica, in order to determine the components responsible for the green color of the endosperm. Both cultivars produce beverage of good quality. Chlorophylls, flavonoids, total diterpens, chlorogenic acid, and K, Ca, Mg, Fe and B ions were determined in beans of both cultivars. No differences between cultivars were found on these component contents, what suggests that the green color may be due to other compounds or that the Cera endosperm may have an inhibitor component of the green color of the coffee beans.
Realizaram-se comparações entre as sementes dos cultivares Mundo Novo de Coffea arabica, cujo endosperma é verde, com as do cultivar Cera, dessa espécie, de endosperma amarelo, com o objetivo de determinar os componentes responsáveis por aquela cor. Nas análises de clorofilas, flavonóides, diterpenos totais, ácido clorogênico e íons Mg, Ca, K, Fe e B, nenhuma diferença foi verificada entre os dois cultivares, sugerindo que a coloração verde se deva à presença de outros componentes ou que o 'Cera' apresente um componente que não ocorre no 'Mundo Novo' e que inibe o desenvolvimento da cor verde no seu endosperma.
