| Abstract: | In this paper,citric acid fermentation residual sugar component analysis,based on a study of degradation pullulanase residual sugar fermentation the optimal conditions and degradation of performance.The results show that the pullulanase of the optimal conditions for the role: t = 28min,T = 58 ℃,pH 4.8,Pullulanase 0.4 mL;in this experiment from optimal conditions,reducing sugar content can increase of 30.7 percent. |
