Abstract The process of determining fatty acid value of wheat flour by benzene extraction method was studied. Each uncertainty component of the method was analyzed. The modeling, component calculation, synthetic standard uncertainty and extended uncertainty in the uncertainty evaluation were described.The results showed that when the fatty acid value of wheat flour was 54.8mg/100g, the expanded uncertainty was 1.2mg/100g, k=2. Blank test was the main reason for introducing uncertainty.
