Abstract: To research the optimum fermentation conditions for alcohol production by residue from diosgenin processing, several important factors were analyzed in the orthogonal test of five factors and four levels. The content of alcohol was valued as an evaluation index using spectrophotometry. The results indicated that the linear range of calibration curve was 0.028%~0.24% (r=0.9998) after color reaction, and optimal fermentation conditions were determined as follows:the use level of α-amylase as 7 U/g, cellulase 110 U/g, glucoamylase 110 U/g, yeast 0.04 g/g, and 4 days fermentation time.
