Abstract: [Objective]To study the uncertainty evaluation of milk powder solubility. [Method]The determination was conducted according to GB 5413.29-2010.A mathematical model for measurement was set up,and the uncertainty components were analyzed. The uncertainty of each influencing factor in the model is evaluated and calculated,the relative standard uncertainty is synthesized,and the relative expanded uncertainty is calculated. [Result]The confidence probability is 95%,the solubility of milk powder is X=（99.97±1.60）g/100g,k=2,the extended uncertainty evaluation of solubility of milk powder is U=1.60 g/100g （k=2）. [Conclusion]It can be provided reference for uncertainty evaluation of milk powder solubility.
