Estudo do teor e composição do óleo de algumas variedades de café (Coffea arabica L.)

Abstract: No presente trabalho foram determinados os teores de extrato etéreo de 19 variedades de café, no estado verde, no torrado, nas bôrras de obtenção caseira da infusão e na bôrra de extração de café solúvel, bem como a fração insaponificável e composição em ácidos graxos de cada óleo. Foi calculada também uma correlação entre o teor de óleo e o extrato aquoso do café torrado.Observou-se que o teor de óleo no café verde variou de 10 a 13% ; no café torrado de 12 a 17% e nas borras do processo caseiro de 7 a 18%.A … Show more

“…2A) and different species of Coffea (Fig. embryos averaged about 10-12% and 28-36%, respectively (Eira et al, unpublished), values that are consistent with previous reports (reviewed by Pinto, 1961;Tango and Carvalho, 1963;Fonseca and Gutierrez, 1971). Similar results were also obtained using excised embryos: there appeared to be no differences in isotherm characteristics at 25°C among embryos of different species or cultivars (Figs 2C, D).…”

“…The dashed line represents the isotherm for soybean cotyledons at 25°C (Vertucci and Roos, 1993). embryos averaged about 10-12% and 28-36%, respectively (Eira et al, unpublished), values that are consistent with previous reports (reviewed by Pinto, 1961;Tango and Carvalho, 1963;Fonseca and Gutierrez, 1971). Embryos tended to adsorb less water than their whole seed counterparts, and this difference can be partially attributed to lipid composition.…”
