| 摘 要： | 对腰果梨抑菌活性物质的提取工艺进行研究,分析比较提取物对不同测试菌的抑菌效果。以金黄色葡萄球菌和白色念珠菌为指示菌,在单因素试验基础上通过中心组合试验设计分别对黄色、红色两种不同色泽腰果梨进行提取工艺优化。得出黄色腰果梨最佳提取工艺:乙醇体积分数70%,提取温度85℃,料液比1:13.9,提取时间2.65h;红色腰果梨最佳提取工艺:乙醇体积分数70%,提取温度85℃,料液比1:14.5,提取时间2.44h。经工艺优化后腰果梨提取物显著提高了抑菌效果。

| Abstract: | Antibacterial materials were extracted from cashew apple and the inhibitory effect of the extract on different test strains was evaluated. Single-factor and central composite experiments were used to explore the optimal extraction processing parameters for antibacterial materials from yellow and red cashew apple using Staphylococcus aureus and Candida albicans as the indicators. The optimal extraction processing parameters for antibacterial materials from yellow cashew apple were ethanol concentration of 70... |
