Objective To establish a method to determine zinc content in Pinghu egg preserved in rice wine by microwave digestion-flame atomic absorption spectrometry. Methods Samples was added by di-gested solution including 8 mL HNO3 and 2 mL H2O2, and determined by microwave digestion-flame atomic absorption spectrometry after multi-step warming program. Results Zinc content in Pinghu egg preserved in rice wine ranged from 18.10 mg/kg to 24.76 mg/kg, zinc recovery rate was 96.45%～103.27%, and the relative standard deviation (RSD) was 2.07%. Conclusion The developed method is easy to operate, environ-ment-friendly with high recovery rate. The result is accurate and reliable.
