1. Effect of decaffeination of green and roasted coffees on the in vivo antioxidant activity and prevention of liver injury in rats
Decaffeination and roasting affects the composition of the chlorogenic acids in coffee, which have antioxidant potential. The aim of this study was to evaluate the effects of coffee decaffeination on the in vivo antioxidant activity and the prevention of liver damage. The Wistar rats received intraperitoneal doses of carbon tetrachloride and daily doses of A

2. Classificação do café beneficiado: uma proposta para pagamento pela qualidade dos grãos
Brazil is the largest world coffee producer and exporter. The crop arrived in the country in the colonial period, in the mid-seventeenth century, and during much of the nineteenth and twentieth centuries was the Brazilian main export product. Brazil produces coffees of different qualities. In raw grain status, the product is traded after being benefited in t

3. Certificação de origem através da Indicação Geográfica para o café Cerrado Goiano / Certification of origin through the Geographical Indication for coffee "Cerrado Goiano
Although the coffee cropping in the State of Goiás is more recent and the produced volumes are lower among the traditional coffee producers in Brazil, it presents both climate and soil characteristics similar to those of the savannah in Minas Gerais. This research was carried out to evaluate the viability of the certification for coffee cropping in the Stat

5. Determinação simultânea de precursores de serotonina - triptofano e 5-hidroxitriptofano - em café
Epidemiological studies attributed positive effects in the central nervous system (CNS) to coffee. Among possible active constituents, serotonin, a neurotransmitter in the CNS, is present; but dietary sources do not cross the blood-brain barrier. Tryptophan and 5-hidroxytryptophan (5-HTP) are serotonin precursors and can affect brain concentrations. An ion-p

7. INTERNATIONAL MARKETING STRATEGIES: A CASE STUDY WITH ORGANIC COFFEE PRODUCERS IN BRAZIL / ESTRATÉGIAS DE MARKETING INTERNACIONAL: UM ESTUDO DE CASO COM PRODUTORES DE CAFÉ ORGÂNICO NO BRASIL
Coffee is the world`s second biggest wealth producer, but only 9% remain with the coffee producers. In Brazil, world`s major producing country and exporter of green coffee, the small and medium producers, through the harvesting of special coffees (such as the organic) and through the production of industrialized coffee, try to increase the value of their exp

8. Diseases under organic cultivation of coffee (Coffea arabica L.): epidemiology and alternative control / âDoenÃas em cultivo orgÃnico do cafeeiro (Coffea arabica L.) : epidemiologia e controle alternativoâ
In the years of 2005 and 2006 two trials were installed in eight year old coffee plantations of the cv. Acaià MG-474-19, under organic and conventional crop systems, in Santo AntÃnio do Amparo, Minas Gerais. The progress of rust and brown eye spot diseases of coffee was assessed as a function of the effect of different biofertilizers, between December/2004

11. Estudo de diferentes processos de torração de café por metodo convencional e microondas
The objective of this study was to contribute a greater knowledge about different coffee roasting processes by both conventional and microwave methods, comparing the effects on different qualities of arabica coffee (hard to better, soft and very soft). Thus experimental coffee roasting conditions were developed [domestic and rapid (industrial) at 210°C and

12. Pharmacological characterisation of extracts of coffee dusts.
The contractile or relaxant activities or both of aqueous extracts of green and roasted coffees were assayed on isolated guinea pig tracheal spirals. Contractile and relaxant activities were compared with histamine and theophylline, respectively. Green coffee extracts induced concentration dependent contraction, but the maximal tension never exceeded 76.3% +
