#$%^&*AU2020101061A420200730.pdf#####Abstract The invention provides a method for measuring soluble sugar content of sweet sorghum stem dry samples, which comprises the following steps of: preparing reagents; Sample determination; Using colorimetry to determine the absorbance of compounds to judge the sugar content of sweet sorghum stalks. Phenol sulfuric acid method is a simple method for determination of soluble total sugar, with cheap reagents, less experimental instruments and higher sensitivity. It is basically not affected by the presence of protein in the experimental process, and the generated color can be stabilized for about 3h, which is convenient for experimentaloperation.Description of Drawings 0.8 y 0.0056x + 0.0163 0.6 - R2=0.9929 0.4 0.2 0.0 15 35 55 75 95 115 Different Sucrose Concentrations (pg) Figure 1 3.0 -Dry Sample Fresh Sample 2.5 2.0 0 1.1 0. 10/
