Abstract
The nutritional value of coffee as primary beverage in the world can vary according to different factors, including the species and the geographical origin where the beans are produced. In this study, indicators of humidity, organic matter, ash, protein, fat and fiber from coffee samples of the variety Robusta (Coffea canephora) originally from Mexico, Brazil and Vietnam, were evaluated. The highest percentage of humidity (6.1), organic matter (96.2) and fat (6.7) were observed in samples of coffee beans from Mexico. The percentage of fiber (21.9) was higher in the samples from Vietnam, while ash (4.10) and the protein (10.3) were higher in samples from Brazil. This shows that the countries of origin of coffee beans influence their nutritional value and that in the market in Mexico we can find variation in these indicators.
