Oil content of green beans from some coffee species

The oil content was determined in seeds of several continental African species of the coffee germplasm bank of Instituto Agronômico de Campinas, State of São Paulo, Brazil. Oil was extracted from seeds with hexane in Soxhlet apparatus. Due to the economic importance, C. arabica and C. canephora have...

Description
Summary:The oil content was determined in seeds of several continental African species of the coffee germplasm bank of Instituto Agronômico de Campinas, State of São Paulo, Brazil. Oil was extracted from seeds with hexane in Soxhlet apparatus. Due to the economic importance, C. arabica and C. canephora have been the best studied species concerning oil content and composition, and the results obtained are in agreement with the reported in the literature. On the other hand, only one report in the literature describes the results of oil analyses in other few species of the African continent, although it does not allow comparison with our results. The oil content of most of the species varied from 9 to 15%, therefore, similar to the range observed for C. arabica and C. canephora. The exception was C. salvatrix, with 29% of oil in the seeds. O teor de óleo foi determinado nas sementes de várias espécies de café do continente africano, presentes no banco de germoplasma do Instituto Agronômico (IAC), as quais foram extraídas com hexano em extrator Soxhlet. Em vista de seu valor econômico, as espécies C. arabica e C. canephora têm sido as mais estudadas no que diz respeito ao conteúdo de óleo e sua composição, e nossos resultados são concordantes com aqueles da literatura. Por outro lado, apenas um trabalho publicado relata análises de óleo em outras poucas espécies do continente africano, não permitindo total comparação com nossos dados. De modo geral, os valores obtidos para a maioria das espécies situaram-se na faixa 9 e 15%, semelhante, portanto, à encontrada para C. arabica e C. canephora. A exceção foi C. salvatrix, com 29% de óleo nas sementes.
