摘要
为了研究山药、金银花、玉竹、沙参、夏枯草、淡竹叶等中药对啤酒酵母发酵的影响,在麦汁制备过程中添加适量的中药(0～2.0%),接种啤酒酵母发酵7 d,测定啤酒酵母数、pH、CO2失重、酒精度、残糖等指标。结果表明,玉竹对啤酒酵母的生长代谢影响不大;山药和金银花随着添加量的增加对啤酒酵母的生长代谢呈抑制作用;夏枯草和淡竹叶对啤酒酵母的生长代谢具有一定的促进作用。
To investigate the effects of Dioscorea opposita, Lonicerae japonicae, Polygonatum odoratum, Radix adenophorae, Prunella vulgaris, Herba lophatheri on the fermentation of Saccharomyces cerevisiae, proper amount of these Chinese traditional medicines were added in wort at 042.0 %. Then S. cerevisiae was inoculated in the wort, after 7 d fermentation, the amount of yeast, pH value, CO2 release, alcohol content, and residue sugar content were determined. The results showed that P. odoratum had insignificant effects on Saccharomyces cerevisiae fermentation, however, D. opposita and L. japonicae inhibited the growth and the metabolism ofS. Cerevisiae, and P. vulgaris and H. lophatheri could promote the growth and the metabolism ofS. cerevisiae.
