Nutrient profile of black coffee consumed in Serbia: Filling a gap in the food composition database

Accurate food composition data is essential in calculating the nutrient intake of a population based upon its consumption statistics. In the Serbian Food Composition Database (FCDB) there is a lack of reliable analytical data for black coffee, even though this is one of the most abundantly consumed beverages. In addition to evaluating the nutritional significance of black coffee consumption in Serbia, this work provides analytical data for inclusion in the Serbian FCDB, and the interchange through EuroFIR FoodEXplorer. Macronutrient, caffeine, chlorogenic acids (CGA), fatty acids and mineral content were analysed in a composite sample of roasted ground coffee, as well as in weak and strong infusions prepared in a traditional way. The macronutrient content of black coffee is in accordance with data from other FCDBs, confirming it to be of low-energy value and a modest contribution to the dietary intake of macronutrients. At the same time, consuming 200 mL (2 cups) of a strong infusion per day could provide more than 7.5% of the daily reference intake of potassium. The obtained results for caffeine and CGA in the investigated coffee infusions highlight the generally high daily consumption of these biologically active non-nutrient compounds among the Serbian population.
