干白葡萄酒清除DPPH自由基的能力及其与总酚含量的关系
DPPH Free Radical Scavenging Activity of Dry White Wine and the Correlation of Total Polyphenol
摘要
Abstract
The purpose of this study include the assessment of the scavenging effect（on DPPH） of dry white wine samples by ESRS and the analysis on the relation between the scavenging effect and phenolic composition.The conditions for ESRS determination indicated by the result are reaction time 10min and dilution times 30 times.The Origin 8.0 was used to integrate the samples spectroscopic of ESR.Their correlation of the scavenging activity and total polyphenol content of different varieties＇ dry white wines was achieved.In Sauvignon blanc,the ability of scavenge free radicals was the best since it attained to 68%and its total phenols content was 311 mg/L;the scavenging effect of dry white wines on DPPH free radicals was positively correlated with their total phenols content.关键词
