Abstract
Ten sweet cherry cultivars were analysed for their content of acids. The acids were precipitated as lead salts, and measured as trimethylsilylderivatives (TMS), applying gas-liquid chromatography (GLC) and gas chromatography/mass spectrometry (GC/MS). The results confirmed that malic acid is dominating in sweet cherry fruits, comprising 70–85% of total acidity, and also the presence of quinic, citric, chlorogenic and phosphoric acids. Acids not formerly found in sweet cherries were galacturonic, glucuronic, glucaric mono-lactone, gluconic, and oxalic. Cultivar and degree of ripeness had little influence on type and amount of acids present.
