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.

Key words: beer yeast, fermentation, sweet potato starch, beer auxiliary material
