Abstract:In this manuscript,a kind of low-alcohol-content EF wines was produced by co-fermented EF seed kernel and glutinous rice in a specific ratio was developed. The major nutrients, polyphenol components in the EF wines and the antioxidant activities were also investigated. The results showed that high contents of protein,essential amino acids and total phenols were found in the new and aging EF wines,the wines,especially aging EF wine,have good flavor and some quality characters have reached a semi-dry rice wine national standards. The HPLC analysis results showed that four kinds of polyphenol components were identified form EF wines,such as gallic acid,ferulic acid,quercetin and rutin. During aging,the rutin in new EF wine was completely transformed into quercetin in aging EF wine. The EF wines all exhibited strong antioxidant activities and nitrite-scavenging capacities,and these activities may be closely related to the high contents of reducing sugar and polyphenols constituents in the EF wines. The results indicated that the EF wine is nutritious and has strong antioxidant activity in vitro.
