Abstract: In this paper, the six Aigma DMAIC method was used to systematically analyze and study the process affecting the good rate of blank value of cytological method for dairy products. Through data collection, analysis and verification in each link, the room for improvement in the experimental process was identified. C&E matrix and FMEA were used to analyze the factors affecting the good rate of blank value. Through the DOE experiment design method and risk analysis, the main influencing factors were optimized and improved. The optimized experimental conditions were: silica gel activation temperature (500±50)℃, activation time (23±1) h, cells adherent rate (95±1)%, and single-use of 1.5 mL conical flask. Under the above conditions, the good rate of blank value of cytological method was improved from 52.8% to 100%. The improvement of these conditions is of great significance to ensure the accuracy of results, save the testing cost and improve the testing efficiency.
