摘要: 本实验研究了酵母在红薯淀粉做辅料的麦汁中的发酵特性,并与其在大米做辅料的麦汁中的发酵特性作了对比,结果表明其完成主发酵所用的时间、可发酵浸出物的变化、还原糖含量的变化、α-氨基氮的利用情况、双乙酰的生成量等均无明显的区别,而且酵母的生长繁殖正常。红薯淀粉作辅料的啤酒色度较大。

Abstract: The fermentation performance of yeast in the wort with sweet potato starch for beer was studied in this research.Compared with the wort that with the rice as auxiliary material:the time for fermentation,changes of formentable extract,changes of reductive sugar,usage ofα-amino nitrogen,and producing amount of diacety are similar during fermentation.The chroma of mellowed beer is higher than the pale beer.
