| 中文摘要: |
| 采用乙醇提取法对圣女果果皮色素进行浸提，通过正交设计优化其提取效果，并采用体外模型判断方法，通过分析果皮色素，对超氧阴离子自由基、羟基自由基、DPPH 的清除能力研究圣女果果皮色素的抗氧化能力。结果显示，采用 90%乙醇+0.5%柠檬酸（5：1，V/V）的混合液作为浸提溶剂，提取时间为 70 min，料液比为 1：14（g/mL），pH值为 4.0 时，圣女果果皮色素的提取可达到最佳效果。优化后的工艺成本低、操作简单、安全性较高，在工业中有很好的发展前景。 圣女果皮色素提取液的浓度与其对超氧阴离子自由基、羟基自由基和 DPPH 的清除作用呈现一定的正相关关系。 |
| 英文摘要: |
| The extraction techniques of pigment from cherry tomato peel by solvent method were studied on the basis of single factor test and orthogonal test. The results suggested that the optimal technical condition was as follows: the best extraction technology was extracted solution of 90% ethanol + 0.5% citric acid (5, V/V) in the mixture, the ratio of cherry tomato peel and extraction being 114 (g/mL), the pH was 4.0 and the extraction time was 70 min. This extraction technology, taking the ethanol as the extraction solvent, had features of low cost, easy operation and high safety, and had
good prospects for development in the industry. The virgin skin pigment extract on the superoxide free radical scavenging
effect and hydroxyl free radical scavenging effect and DPPH radical was positively correlated with concentration. |
