摘　　要：以脱皮的青稞米为原料,接种红曲粉、甜酒曲进行固态发酵,以多酚含量、黄酮含量、酒精度和感官评分作为评价指标,采用单因素试验和正交试验优化富含酚类物质的青稞酒发酵工艺条件,并测定其体外抗氧化活性。结果表明,红曲霉固态发酵青稞酒的最优工艺条件为:以3次脱皮的青稞米为原料,粉碎处理的红曲作为发酵剂,料液比1∶1.0(g∶mL),加曲量15%,发酵温度27℃,发酵16 d。在此条件下,青稞酒的总酚质量浓度为1823.31 mg/L,黄酮质量浓度为127.00 mg/L,酒精度为8.5%Vol,感官评分为82.2分,DPPH·清除能力为1202.11μmol/L,ABTS·清除能力为5577.00μmol/L,FRAP铁还原能力为2000.50μmol/L,具有较强的抗氧化活性。Taking peeled barley rice as raw material,inoculatist red yeast powder and sweet wine koji for solid fermentation,taking polyphenol content,flavonoid content,alcohol content and sensory score as evaluation indicators,using univariate,orthogonal tests to optimize the fermentation process conditions of phenol-rich barley wine,and determining its in vitro antioxidant activity,the results showed that the optimal process conditions for aspergillus red yeast fermented barley wine were:3 times peeled barley rice as raw material,crushed red yeast as a starter,feed-to-liquid ratio of 1∶1.0(g∶mL),and the amount of koji 15%,fermentation temperature 27℃,fermentation 16 days.Under this condition,the total phenol content of barley wine was 1823.31 mg/L,the flavonoid content was 127.00 mg/L,the alcohol content was 8.5%Vol,the sensory score was 82.2 points,the DPPH clearance capacity was 1202.11μmol/L,the ABTS·scavenging capacity was 5577.00μmol/L,and the FRAP iron reduction capacity was 2000.50μmol/L,which had strong antioxidant activity.
