Abstract:

A method for determination of food colorant Red 2G in high protein food was developed. The extractant, sorbent and separation parameters of chromatography were optimized. In this study, this method was applied to determine Red 2G in sausage. The experiment results indicated that the recovery rates for adding 2 and 8 mg/kg of Red 2G standard to sausage samples are 90% to 104% and 89.98% to 94.00% respectively, and the RSDs are 9.37% and 2.82% respectively. The method developed in this study can be applied to food safety assay satisfactorily.

Key words: Red 2G, high protein food, sausage, solid phase extraction, determination method
