Analysis of anthocyanin composition in different red grape varieties and wine from the eastern foot of Helan Mountain
Eight Eurasian wine red grape varieties were selected as raw materials,the anthocyanin contents and compositions in different grape varieties and wine were analyzed by high performance liquid chromatography-mass spectrometry(HPLC-MS),and the characteristics of components were ex-plored.The results showed that there were significant differences in basic physicochemical indexes and anthocyanin component contents among dif-ferent red grape varieties and wine.Five classes of anthocyanins were detected in 8 tested grape varieties,classified into nine monomeric anthocyanins according to the degree of methylation and acylation,Cabernet Sauvignon,Matheran and Syrah wines had darker color than other varieties,which corresponded to higher total anthocyanin content in grape skins and wines,while Meili and Merlot present the opposite results.Cabernet Sauvignon,Matheran and Syrah had higher levels of delphindin in their grape pericarp,particularly malvidin-3-O-glucoside,which were(35.33±0.29)mg/g,(24.68±0.94)mg/g and(27.07±0.01)mg/g,while Meili and Merlot had higher levels of cyanidin and lower degree of anthocyanin modification in the grape pericarp and wines than other varieties(P＜0.05).The results showed Cabernet Sauvignon,Matheran and Syrah had high contents of anthocyanin,the wines had good color and were more stable during the aging process,which were suitable for making deep-colored wines.
