| 摘 要： | 为了提高核桃资源的综合利用程度,对核桃壳棕色素提取技术进行试验研究。以棕色素的提取率为目标,采用单因素试验方法考查乙醇体积分数、提取时间、提取温度、液料比对棕色素提取率的影响,并应用回归正交方法建立三元二次方程优化棕色素的提取工艺。结果表明,核桃壳棕色素适宜的提取条件是乙醇体积分数52%、提取时间4.8h、提取温度70℃、液料比5:1(mL/g),在此条件下,核桃壳棕色素提取率为5.0496%,可用于工业化生产。

| Abstract: | In order to improve the comprehensive utilization of walnut resource,the extraction of brown pigment from walnut shell was explored.On the basis of one-factor-at-a-time experiments,a three-variable quadratic equation was established by orthogonal regression design to describe the effects of ethanol concentration,temperature,extraction time and material-to-liquid ratio on the extraction rate of brown pigment.Through resolving the equation,the optimal conditions for extracting brown pigment from walnut shell ... |
