-"The analysis results for seven of the aroma compounds obtained by vacuum distillation from sweet and sour cherry products were compared. The freshly pressed juices from 5 varieties of sour and 5 varieties of sweet cherries showed great differences in concentrations (μg/1): benzaldehyde (18393), linalool (0.51.7), hexanal (0.354.7), 2(E)-hexenal (2.4220), 2(E),6(Z)-nonadienal (0.12.4), phenylacetaldehyde (2.15.6) and eugenol (1.022.2). The benzaldehyde content of the juices showed the highest correlation to the recognition threshold of the cherry aroma note. The cherry jam showed a drastic change in the aroma composition: benzaldehyde and linalool increased greatly (7 and 13-times, respectively), while hexanal, 2(E)-hexenal and phenylacetaldehyde strongly decreased. The increase in benzaldehyde and linalool, which was also observed during simultaneous distillation/extraction of the juices, is caused by the hydrolysis of the corresponding glycosides during the heat treatments." \\+"The analysis results for seven of the aroma compounds obtained by vacuum distillation from sweet and sour cherry products were compared.
