响应面法优化二氧化氯杀灭蛋壳大肠杆菌工艺研究

Optimum process of Escherichia coli of chlorine dioxide inactivation on eggshell by response surface methodology

利用DesignExpert软件,根据Box-Behnken设计(BBD)原理采用四因素三水平的响应面分析法,对二氧化氯杀灭鲜蛋蛋壳大肠杆菌的条件进行了研究,获得了二次多元回归模型。对模型进行手动优化,利用优化模型优化出十组杀菌工艺参数,并对工艺参数进行了验证。

By using Design Expert software,in accordance with theory of Box-Behnken design,the condition that Escherichia coli of eggshell of fresh eggs killed by chlorine dioxide as a response of four variables was researched.Then the fitted multivariate quadratic regress model was obtained.The model was optimized by manual operation.By utilizing optimization model,process parameters of ten groups were optimized.The process parameters were tested and verified.
