Abstract

This paper contains data regarding the concentration of some essential mineral elements in certain coffee brews and their mineral supply in the daily-recommended diet. We determined, through flame atomic absorption spectrometry, the concentration of Na, K, Ca, Mg, Fe, Mn, Zn and Cu in brews made with five assortments of coffee. The mean values of the concentrations determined experimentally – 34.90 mg/L (Ca), 21.49 mg/L (Mg), 1.180 mg/L (Na), 522 mg/L (K), 0.158 mg/L (Fe), 0.206 mg/L (Mn), 0.146 mg/L (Zn), 0.027 mg/L (Cu) – allowed the calculus of their mineral supply. Data show that an intake of 300 mL coffee brew covers in a small measure the daily recommended intake of essential elements; therefore, coffee brews cannot be taken into account as far as their mineral supply is concerned.
