| Abstract: | Objective] To optimize drying parameters of Xinjiang fresh horse milk frozen by response surface method.Method] In vacuum condition,with Xinjiang fresh mare＇ s milk concentration ratio,thickness and sublimation drying time as investigation factors,bulk density,flowability and total protein content as investigation indicators,on the basis of single factor test,using Box-Behnken center combination design,the frozen and drying parameters of Xinjiang fresh horse milk was optimized by response surface analysis method.Result] The regression model of frozen and drying factors and Xinjiang fresh mare＇s milk powder was established; through response surface analysis,the optimum vacuum frozen and drying technique parameters are：Xinjiang fresh mare＇ s milk thickness 1.02 cm,the sublimation drying time 24.87 h,the concentration ratio 27％.Conclusion] The model fitting is good,which can provide theoretical reference for industrialization of mare＇s milk and products. |
