Abstract
The effects of the ratio of material to water,amount of saccharifying enzyme,saccharification time,yeast inoculation quantity etc.on extruded sweet potato were studied.The optimal technological conditions through single factor experiment were obtained.The results showed that ratio of material to water was 1.0 ∶2.0,doses of saccharifying enzyme as 110 U/g,saccharification time as 30 min,yeast inoculation quantity as 0.10% was the optimal technological conditions,the alcohol content of fermentation mash was 14.92%(v/v).Compared with the traditional alcohol fermentation process,the alcohol content of fermentation mash had improved 3.07 Percentage Point.Addition of nitrogen source could not strengthen fermentation evidently.
