Abstract

Objective: To explore the content of aldehydes in Baijiu. Methods: A method for the determination of 17 aldehydes in Baijiu was established, and the methodological performance indexes were studied using statistics. Results: Through statistical analysis, the detection limit of 17 aldehydes in Baijiu was determined to be 0.7～5.9 mg/L, the limit of quantification was 1.9～14.6 mg/L, which passes the quality inspection of the calibration curve within the range of 0.6～320.0 mg/L, and the linear relationship meets the requirements. The recovery rate of intermediate standard addition in Baijiu was 73%～114%, the coefficient of variation in the laboratory was ≤11%, and the accuracy deviation range was -18.7%～8.0%. Conclusion: The method can be used for the determination of various aldehydes in Baijiu.
