ABSTRACT
Objective To optimize the processing method of Codonopsis pilozula prepared product by the factorial design and response surface methodology. Method In the two different optimizing processing, methods were optimized respectively on basis of preplanned experiment design and the percentage of extracts were also determined respectively. Drying temperature and time, bran parching temperature and time respectively as independent variable, their OD value as dependent variable, multiple regression equation was obtained and binomial equation was simulated as well. Results The r2 of Codonopsis pilozula dried product and Codonopsis pilozula parched product were respectively 0.976 4 and 0.987 9, meanwhile their optimized processing methods were drying temperature 80 ℃, drying time 2 hours and parching temperature 250 ℃, parching time 1 minute. Conclusion The effect of independent variable to dependent variable can be analyzed on three-dimensional chart with the factorial design and response surface methodology, consequently it will help to optimize processing method of prepared product.
