摘要 [Objectives] To establish a quality control chart of DHA in milk powder and determine whether the detection process and results are in control state. [Methods] The content of DHA in milk powder control samples was determined by gas chromatography, and the quality control chart of DHA was established to analyze the controlled state. [Results] the median of the quality control chart was 23.85 mg/100 g, and the standard deviation was 1.00 mg/100 g. In the evaluation and analysis of the new quality control points, it can be seen that the point beyond the warning limit was 1, and the outlier value was not beyond the action line, and the mean value did not change, indicating that the detection is in the statistical control state, and the detection process, method and results are controlled. [Conclusions] The establishment and review of the control chart in this study are expected to provide a reference for other subsequent quality controls.
