二氧化氯对榨汁苹果表面腐生酵母菌杀菌规律的研究

Study on Sterilizing Regularity of Chlorine Dioxide on the Saprophytic Yeast on Surface of Juice-Squeezed Apples

应用中心组合实验设计方法(CentralCompositeDesign)研究了二氧化氯对榨汁苹果原料表面的腐生酵母的杀菌规律。通过回归分析,用数学模型的方式表示了二氧化氯对苹果表面腐生酵母菌的杀菌规律,指出了几个主要影响因素:作用浓度、杀菌时间、杀菌液值和灭菌温度与杀菌效果的之间的关系。通过对得出的数学模型的验证,证明该方程可以用于描述二氧化氯对腐生酵母的杀菌规律,并可对杀菌效果进行较准确的预测。

The Central Composite Design was used to investigate the sterilizing regularity of chlorine dioxide on saprophyticyeast on the surface of the apples for juice-squeezed. Through regression analysis, a mathematic model was established todescribe the relationship between sterilizing result and its main influential factors, such as concentration, sterilizing time, pH ofsterilizing liquid and sterilizing temperature. It was verified that this mathematic model could be used to describe the sterilizingregularity of chlorine dioxide on the saprophytic yeast and to forecast the sterilizing efficacy in a relatively accurate manner.
