Taking glucose, fructose, sucrose and potato starch as standard, the total sugars in potato residues and potato starch deep-processing waste liquid were determined.The optimum experimental conditions were studied.Hydrochloric acid is added to the waste liquid and the solution is digested for 120 minutes at 105 degree celsius.The solution was decolorized with activated carbon and filtered.Anthrone is added to the filtrate.The filtrate is heated in boiling water bath for 12 min and the color system reaches its optimum value for absorbance at 620nm.The sugar concentration follows Beer's Law in the range of 1-100μg/mL.The linear correlation is 0.9997.The method was used in the total detection of total sugar of potato starch deep-processing waste liquid from Liangshan prefecture yanyuan shifu agriculture and technology corporation is determined.The relative error is within 5% and the recovery of standard addition is between 96.42% and 103.16%.The result is satisfactory.
