Identification of Volatile Compounds in Blackcurrant Berries: Differences among Cultivars
Résumé
Berries of blackcurrant are known to produce a strong flavor. Some previous studies
have reported that a given cultivar of blackcurrant can produce berries with a specific profile of
volatile compounds. For the Burgundy region in France, the Noir de Bourgogne cultivar is especially
important because it is the main ingredient of a liquor with a designation of origin. The aim of the
present study was to characterize the volatile fractions of berries from 15 cultivars in order to explore
the possibility of using different cultivars for liquor production. The plants were cultivated under
the same conditions and harvested in the same year. The volatile fractions of the harvested berries
were analyzed using HS-SPME-GC-MS. Thorough univariate statistical analysis and multivariate
analysis were applied to the dataset, which made it possible to identify groups within cultivars. The
Rosenthal cultivar exhibited a quite flat profile; the Lositkia, Ben Tiran, and Barchatnaia cultivars
shared common features; the Noir de Bourgogne cultivar showed the highest amounts of molecules
such as 3-carene, limonene, β-phellandrene, ocimene, α-terpinolene, and bicyclogermacrene. None
of the studied varieties were close to the Noir de Bourgogne on the basis of VOC analysis.
