Extraction of Antiyeast Protein from Barley Malt and Determination of Optimum Conditions

Abstract:

In this study,the effect of ulfuric acid concentration,extraction time and ratio of water to material on the extraction of antiyeast protein from barley were determined,the optimum conditions of antiyeast protein extraction were described as follows∶sulfuric acid concentration 0.05 mol/L,extraction time 3.6 h,ratio of water to material 1∶5.75.with the optimum extraction conditions,the best extraction rate achieved at 391.8 μg/g.
