| 摘 要： | 为充分利用农业废弃物柑橘皮，进一步提高皮中果胶的提取效率，在Placket-Burman试验的基础上，采用Box-Behnken中心组合设计对橘皮果胶复合酶提取工艺中的时间、温度和酶添加量3因素的最优化组合进行定量研究，建立并分析各因素与果胶得率关系的数学模型。结果表明：最佳的工艺条件为酶解时间5.1h、温度41℃、复合酶添加量0.46%。在此条件下经实验验证，果胶得率理论值12.35%，验证实测值12.22%，相对误差1.05%；说明回归模型能较好地预测橘皮中果胶的提取得率。经检测，产品果胶所有指标均达到或超过国家标准。

| Abstract: | In order to optimize the extraction of pectin from citrus peel as an agricultural waste by simultaneous hydrolysis with cellulase and hemicellulase,the effects of three key factors including extraction time,temperature and total enzyme amount on the extraction rate of pectin were explored by Box-Behnken experimental design based on Placket-Burman design,by which the optimal initial pH,mass ratio of cellulase and hemicellulase,ratio of solid to liquid and material granularity were determined to be 4.5,1:1,1:... |
