摘要: 本研究以蓝花楹花朵为原料，采用超声波辅助提取的方法，通过响应面优化提取工艺，探究浸提液料液比、温度、提取时间、柠檬酸溶液浓度等对蓝花楹色素提取率的影响，获得最佳提取工艺条件。以及探究蓝花楹花色素在光照、温度、酸碱性、金属离子条件下的稳定性。结果显示，各因素影响大小为：超声温度 > 柠檬酸浓度 > 提取时间。最佳提取工艺为：料液比1:40、温度40℃、时间25 min、柠檬酸浓度10%，此时提取率达15.008%。稳定性研究表明，该色素在光照、高温(≥80˚C)、碱性条件及金属离子存在下均不稳定，但在酸性环境中稳定性良好。
Abstract: In this study, Jacaranda mimosifolia (D.) Don were used as raw materials. Ultrasonic-assisted extraction combined with response surface methodology was adopted to optimize the extraction process. The effects of solid-liquid ratio, extraction temperature, extraction time and citric acid concentration on the extraction rate of jacaranda pigment were investigated to obtain the optimal extraction conditions. Meanwhile, the stability of jacaranda anthocyanin under light, temperature, pH and metal ions was explored. The results showed that the influence order of factors was: ultrasonic temperature > citric acid concentration > extraction time. The optimal extraction conditions were solid-liquid ratio of 1:40, temperature of 40˚C, extraction time of 25 min and citric acid concentration of 10%, with an extraction rate of 15.008%. Stability tests indicated that the pigment was unstable under light, high temperature (≥80˚C), alkaline conditions and metal ions, while it exhibited good stability in acidic environments.
