摘要
在单因素试验基础上,选取皂化时间、锌代温度和锌代时间作为影响因子,应用Box-Behnken中心组合设计建立数学模型,以叶绿素锌钾盐产率为响应值,进行响应面分析(RSA)。结果表明,叶绿素锌钾盐的最佳制备工艺为皂化时间58 min,锌代温度57℃,锌代时间83 min。响应面模型在此条件下预测的叶绿素锌钾盐产率为8.95%,验证值(9.23%)与预测值相对误差3.13%。
Response surface method（RSM） was used for optimizing the preparation technology of potassium zinc chlorophyllin.Based on single-factor experiment,saponification time,temperature of zinc reaction and time of zinc reaction were selected as influencing factors during extraction.The experiment mathematical model was arranged according to Box-Behnken central composite experiment design.The results showed that the optimum preparation technology for potassium zinc chlorophyllin were saponification time 58 min,zinc reaction temperature 57 ℃,zinc reaction time 83 min.The predicted productivity ratio of potassium zinc chlorophyllin was 8.95%,and the verification productivity ratio was 9.23%,with relative error of 3.13%.
