Effect of fermentation alcohol termination by ceramic membrane filtration on the aroma of sugarcane fruit wine

Abstract

The study aimed to explore the impact of ceramic membrane filtration used to terminate the fermentation process on the aroma of low-alcohol sugarcane fruit wines as compared to traditional methods. The sugarcane fruit wine of termination fermentation by ceramic membrane filtration results in a more fruity character due to the higher content of some volatile compounds (hexanal, hexyl butanoate, butanoic acid butyl ester, hexanoic acid ethyl ester, and β-Damascenone). In comparison to traditional method (pasteurization), sugarcane fruit wine of termination fermentation by ceramic membrane filtration exhibits a greater abundance of the characteristic aroma compounds (hexanal, isobutyl isobutyrate, pentanal, and butanal) of sugarcane juice, resulting in a more pronounced sugarcane aroma. In addition, results showed that a total of 73 volatile compounds were identified in sugarcane wine, with 17 being identified as key differential compounds and 20 as key aroma-active compounds.
