| 摘 要： | 以使用硫酸调节纯水得到的酸性水为溶剂，采用高效液相色谱测定柠檬苦素含量，浸提柑橘皮渣中柠檬苦素。在热浸提时间、温度及料液比单因素试验的基础上，利用三元二次旋转组合试验设计优化提取条件，建立三因素与柠檬苦素得率之间的数学模型。结果表明，酸性水提取柑橘皮渣中柠檬苦素的最佳工艺条件为提取时间2.6h、温度61.2℃、料水比1:19.2(g/mL)、酸性水提取液pH4。在此工艺条件下，柠檬苦素的得率为0.117mg/g。

| Abstract: | The pH of pure water was adjusted with sulfuric acid to provide a solvent for the extraction of limonin from citrus peels.Limonin quantification was performed by HPLC.Based on one-factor-at-a-time experiments,a three-variable quadratic rotary unitization design combined with response surface methodology was used to optimize three conditions for acidic water extraction of limonin from citrus peels,and a mathematical model describing limonin yield versus the three extraction conditions was built.The optimal e... |
