Abstract
Strong and characteristic aroma is of main importance in production of black currant products.
Twelve black currant genotypes of different origins, grown at the Dobele Horticultural Plant Breeding Experimental station, Latvia, with very diverse pedigrees and berry quality were analysed for volatile compounds: Zagadka, Katyusha, Yadrenaya, Chernii Zhemchug, Joniniai, Selechenskaya, Mara, Lentyai, No. 67, Stor Klas, AA-98, and No. 3579 (R. nigrum × R. petiolare hybrid). Volatile compounds were collected by dynamic headspace sampling technique (purge and trap) from a mash prepared from fresh frozen black currant berries, and quantified by gas chromatography equipped with a flame ionization detector (GC-FID) and identified by gas chromatography-mass spectrometry (GC-MS). A total of 56 volatile compounds were identified and quantified in the analysed purees.
Remarkable quantitative differences were found for important volatile compounds, such as aliphatic esters, aldehydes and terpenoids of the investigated genotypes.
Aliphatic esters comprised in average 54.8% of the total volatile mass; the major esters were ethyl butanoate (38.2%) and methyl butanoate (12.8%). Terpenoids comprised in average 34.5% of the total volatile mass; the major terpenoids were sabinene (8.1%) and 3-carene (7.0%). Aldehydes comprised in total 8.2% of the total volatile mass with hexanal being the major aldehyde (6.3%). Genotypes AA-98 (14627 ng g-1 puree), Selechenskaya (12481 ng g-1 puree), and Zagadka (10982 ng g-1 puree) had the highest amount of total volatile compounds.
Aliphatic esters dominated in Selechenskaya (82.8%), Stor Klas (74.2%), and AA-98 (64.1%), whereas terpenoids dominated Joniniai (80.6%), No. 3579 (71.3%), Chernii Zhemchug (68.1%), and Mara (62.7%).
