对控制梨多酚氧化酶( P P O)活性的方法进行了研究,以氯化钠、柠檬酸、抗坏血酸为 P P O活性抑制因子,通过三因子二次回归组合设计建立回归方程,从而准确地反映因子和 P P O活性之间的关系,预示抑制因子用量的多少对 P P O 活性的影响程度和趋势,得出三个因子在抑制酶活性作用中的最佳配比,并分析了各因子间的交互效应。
The method of controlling the activity of pear polyphenol oxidase (P P O) was studied. Sodium chloride, citric acid and ascorbic acid were used as P P O activity inhibition factors, and the regression equation was established through the combination of three factors and quadratic regressions to make it accurate And the relationship between P reflectance and P P O activity, indicating the extent and tendency of the amount of inhibitory factor on the activity of P P O, the optimal ratio of the three factors in the inhibition of enzyme activity was obtained and analyzed Interaction between various factors.
