“…Ratios of R-, -, and γ-tocopherols in different varieties of coffee beans were approximately 2:4:0.1 with no δ-tocopherol (23). Tocopherols in coffee from several countries were reported with > R > γ-tocopherol contents in green C. arabica and C. robusta beans but found that γ-tocopherol increased to ratios higher than R-tocopherol in roasted beans (17). The dramatic increase in γ-tocopherol content in roasted coffee beans in that study is confounding since no other studies have reported such high concentrations of γ-tocopherol.…”

“…Os óleos têm importante papel na retenção do flavour do café torrado, e devido aos altos teores em que são encontrados nos grãos, são objetos de vários estudos (CARRERA et al, 1998;GONZÁLEZ et al, 2001).…”

“…9 Os cafés arábica e conilon podem ser caracterizados pelos teores de cafeína, trigonelina, ácido nicotínico, ácidos clorogênicos e alcoóis diterpênicos (caveol e cafestol). 8,13,14 A influência desses compostos específicos na saúde tem sido relatada, destacando-se, além do valor nutricional (ácido nicotínico), sua correlação com a atividade antioxidante e a redução do risco de doenças crônicas degenerativas (cafeína, trigonelina e ácidos clorogênicos). Para diterpenos são descritos efeitos hepatoprotetor e anticarcinogênico, mas também a elevação da taxa de colesterol, atribuída ao cafestol.…”
