Abstract: During the determination of sulfur dioxide in food by distillation method,each parameter of uncertainty was calculated and analyzed,the content of sulfur dioxide was 0.203 7±0.004 8 g/L(95% confidence probability).The results showed that the uncertainty was mainly due to the metered volume of standard solution and the repeated sample determination.

Key words: distillation method, sulfur dioxide, uncertainty
