摘要
该试验选择红枣和山楂为原料酿造果酒,以原料配比、料水比、初始糖度和酵母添加量为评价因素进行单因素试验,在此基础上采用正交试验进行发酵工艺优化。结果表明,果酒酿造的最佳工艺条件为红枣山楂配比3∶1,料水比1∶3(g∶mL),初始糖度21°Bx,酵母添加量0.3 g/L,在28℃发酵7 d。在此条件下所制得的红枣山楂果酒酒精度为12.2%vol,总黄酮含量为25 mg/mL。酒液枣红色,色泽鲜亮,澄清透明,具有浓郁的红枣山楂的香味,酒体醇厚,是一种酸甜适中的低酒精度的混合果酒。
Using jujube and hawthorn as raw materials to brew fruit wine,the raw material ratio,liquid-solid ratio,initial sugar content,yeast addition was optimized by single-factor tests.On this basis,the fermentation conditions were optimized by orthogonal experiments.Results showed that the optimal brewing conditions were jujube and hawthorn ratio 3∶1,liquid-solid ratio 1∶3(g∶ml),initial sugar degree 21°Bx,yeast addition 0.3 g/L,fermentation temperature 28℃for 7 d.Under the conditions,the alcohol content of jujube hawthorn wine was 12.2%vol,and the total flavonoids content was 25 mg/ml.The wine was jujube red,bright in color,clear and transparent,with strong jujube and hawthorn aroma and full-bodied.It was a compound fruit wine with low alcohol content and moderate sweet and sour taste.
