Effects of Three Solvents on Analysis of Aroma Components in Dry Wine of Cabernet Sauvignon by GC-MS

Different solvents were compared to assess their effects on the analysis of aroma compounds in dry wine of Cabernet Sauvignon by GC-MS.Aroma components were extracted with three different solvents and analyzed by GC-MS.The result showed that three solvents led to higher repeatability for aroma components identified in dry wine of Cabernet Sauvignon.The total weight of the aroma components extracted by dichloromethane was the highest in three solvents.64 components were identified by dichloromethane,35 components were identified by diethyl ether-n-pentane(1∶1),and 42 components were identified by diethyl ether-n-pentane(2∶1).Esters were largely extracted by dichloromethane from dry wine of Cabernet Sauvignon,but alcohols were slightly extracted by dichloromethane;alcohols were largely extracted by dichloromethane from dry wine of Cabernet Sauvignon,but esters were slightly extracted by diethyl ether-n-pentane(2∶1).The results of comparison showed that diethyl ether-n-pentane(1∶1) and diethyl ether-n-pentane(2∶1) have greater effect on analysis of aroma components in dry wine of Cabernet Sauvignon,compared with dichloromethane,dichloromethane is greater solvent to analyze aroma components in dry wine of Cabernet Sauvignon by GC-MS.
