Uncertainty Evaluation for Determination of Sodium Cyclamate Residue in Pastries

Uncertainty for determination of sodium cyclamate residue in pastries was evaluated based on GB/T 5009.97-2003.On the basis of determination results，it was concluded that component relative contribution of uncertainty to calculated standard uncertainty.Results showed that when cyclamate of pastry was 0.65 g/kg，expanded uncertainty was 0.023 g/kg.
