| 摘 要： | 以番茄干粉为原料,采用Plackett-Burman试验设计、最陡爬坡试验结合Box-Behnken设计对番茄红色素的提取工艺进行响应曲面优化.研究结果表明；番茄红色素的最大吸收峰为472 nm,提取温度、提取时间、Ca2+浓度对番茄红色素的提取影响显著,最陡爬坡试验表明响应中心为:提取温度50℃、提取时间110 min、Ca2+ 12 mmol/L,最后用Box-Behnken响应面技术建立了关键影响提取率的二次多项式数学模型:Y-0.902+0.09X1-0.039X2+0.046X3-0.139X12-0.104X22-0.070X32+0.056X1X2+0.068X2X3,得到最佳提取工艺为:提取温度为53℃；提取时间为111 min; Ca2+的浓度为13 mmol/L.模型预测结果提取率达到92.30％,验证试验结果提取率达到92.07％.

| Abstract: | Plackett-Burman design(PBD),Steepest ascent experiment(SAE),and Box-Behnken design(BBD) were used to evaluate the influence of related factors on lycopene extraction.The PBD results showed that temperature,time,Ca2+ concentration have substantial influence on lycopene yield.Then SAE was also used to further optimize extraction technology.At last BBD was applied to establish the second-order polynomial equation for lycopene extraction.The results was as follows: Y=0.902+0.09X1-0.039X2+0.046X3-0.139X21-0.104X... |
