Based on the QB/T 5012-2016,the present study employs the Lan-Ainon constant volume method to determine the reduced sugar content in white soft sugar.Additionally,a mathematical model is constructed to analyze and calculate each uncertainty component.The results indicate that the principal factor affecting the uncertainty in the determination of the reduced sugar content is the titration operation process of white soft sugar sample solutions.The reduced sugar content in the white soft sugar sample was found to be(5.404±0.030)g/100 g(k=2).
