摘要
采用四因素二次旋转正交回归组合设计方法对茶绿色素叶绿素锌钠盐的锌代工艺进行研究。结果表明:影响茶绿色素叶绿素锌钠盐得率最大的因素为锌代时间,其次为ZnSO4浓度、锌代温度、及锌代溶液pH值,其最佳制备工艺为溶液pH调至3.0,在72.8℃,用21.5%的ZnSO4溶液锌代89.6 min,TGP-2产品得率可达0.69%。
The manufacture processing of tea green pigment — sodium-zinc chlorophyllin （TGP-2） was studied by using expectant function approach for simultaneous optimization of several variable levels. The results showed that the effect of heating time was the most noticeable, then the concentration of ZnSO4, temperature, and pH successively. The optimum of preparation process was 3.0 pH, 72.8℃, with 21.5% of ZnSO4 concentration for 89.6 min, and the efficiency of yield could reach 0.69%.
