Przedstawiono wyniki oznaczeń zawartości wielopierścieniowych węglowodorów aromatycznych w naparach kawy naturalnej i napojach sporządzonych z kawy zbożowej i kakao. Do oznaczenia i detekcji związków zastosowano chromatografię gazową.
The content of polycyclic aromatic hydrocarbons (PAHs) in chosen condiments commercially available was investigated. The concentration of these compounds in infusion of natural coffee, ersatz coffee and cocoa was determined by gas chromatography. Fluoranthene, pyrene and benz(a)anthracene were the PAHs, which the most frequently were present in infusions of unfiltered natural coffee. Assuming the extraction of PAHs into infusion of natural coffee of about several percent, obtained results are in good agreement with the amount of those compounds in coffee beans. These compounds were found at similar concentration in infusions of ersatz coffee. The highest concentrations of investigated PAHs were found in cocoa and their amount was 0.82 mg per litre of beverage. The content of these compounds in cocoa was several times higher then the content of those in infusion of unfiltered natural coffee.
