摘  要:
对金银木破碎果实首先用溶剂恒温浸提,然后进行超声萃取处理以提取色素。采用响应面优化金银木果实色素超声辅助提取工艺的料液比、超声时间和超声功率。结果表明:料液比、超声时间和超声功率对金银木果实色素超声辅助提取均有显著影响;最优工艺条件为料液比1:15(g/mL)、超声时间30min和超声功率500W;在最优工艺条件下超声提取的金银木果实色素样液稀释10倍后,在450nm波长处的吸光度理论预测值为0.836,而实际实验的吸光度为0.827,二者数值仅相差1.08%。因此,运用响应面法优化的超声辅助提取工艺条件可行。

摘  要:
Following a period of spontaneous solvent extraction at a constant temperature,ultrasonication was applied to enhance pigment extraction from crushed Lonicera maackii fruit.Three extraction parameters including material/solvent ratio,ultrasonication time and power were optimized by using response surface methodology.All the operating parameters had a signif icant effect on extraction eff iciency and the optimal extraction conditions were determined as 1:15(g/mL),30 min and 500 W for material/solvent ratio,ultrasonication time and power,respectively.The predicted absorbance at 450 nm of the pigment extracted under the optimized conditions after 10-fold dilution was 0.836,showing a relative error of only 1.08% in comparison to the experimental absorbance of 0.827.Thus the optimized process established using response surface methodology is feasible for pigment extraction from Lonicera maackii fruit.
