“…Although no biological functions have been assigned, both cafestol and kahweol are of particular interest, especially in human health where they are considered to stimulate cholesterol synthesis Post et al, 2000;De Roos et al, 2001), and also reported to give protection against some types of cancer (Lam et al, 1982, Cavin et al, 1998. A great diversity was observed for diterpene content both at the interspecific (De Roos et al, 1997;Mazzafera et al, 1998) and intraspecific levels (Speer and Kölling-Speer, 2001), suggesting the existence of genetic polymorphism of the enzymes controlling the cafestol / kahweol biosynthesis pathways.…”

“…Within lipids, diterpenes (cafestol: C 20 H 28 O 3 and kahweol: C 20 H 26 O 3 ) represent 10 % of coffee oil and are specific of the coffee genus (Speer and Kölling-Speer, 2001). Although no biological functions have been assigned, both cafestol and kahweol are of particular interest, especially in human health where they are considered to stimulate cholesterol synthesis Post et al, 2000;De Roos et al, 2001), and also reported to give protection against some types of cancer (Lam et al, 1982, Cavin et al, 1998.…”

“…When coffee is prepared by extended boiling, and the beverage is not filtered through paper or a bed of coffee grounds, the terpenoids, cafestol, kaweol and 16-O-methyl cafestol (figure 1), which occur as fatty acid esters, enter the brew (Speer and Kölling-Speer, 2001). These substances are responsible for the reversible elevation in plasma LDL cholesterol observed in some populations, notably A.…”

“…111 As 5-hidroxitriptamidas (componentes principais da cera do café) parecem ser parcialmente responsáveis pela irritação gástrica, pelo que alguns processos tecnológicos que reduzem a camada cerosa (polimento, tratamento com vapor de água e/ou descafeinização dos grãos verdes), poderão ajudar a diminuir esse efeito. 10 Com este objectivo, foram desenvolvidos os chamados stomach-friendly coffees, direccionados para indivíduos mais sensíveis a nível gástrico, sendo já comercializados em alguns países como, por exemplo, a Alemanha.…”

“…O café robusta resiste mais facilmente ao ataque de pragas durante o seu cultivo e é especialmente utilizado para aumentar o corpo e a espuma de algumas bebidas, assim como para a produção de café solúvel. 1 Quimicamente, estas espécies diferenciam-se pelo seu teor em diversos componentes: cafeína (o dobro no café robusta), 2 minerais, 5 compostos fenólicos, 6 trigonelina, 7 aminoácidos, 8 aminas biogénicas, 9 diterpenos, 10 ácidos gordos, 11 esteróis, 12 β-carbolinas, 13 entre muitos outros.…”
