摘要
对微波辅助提取葡萄籽原花青素的工艺进行了研究,通过正交试验确定了微波辅助提取葡萄籽原花青素的最佳工艺条件,即微波功率为中低火、料液比为1∶18、乙醇浓度为60%、微波作用时间50 s,在最佳工艺条件下,原花青素的提取量为18.47 mg/g。
The technology of microwave extraction of proanthocyanidin from grape seeds is studied. The optimum technology conditions are optimized by orthogonal esperiments. The result shows that the best conditions are mid-low firepower of the microwave, 1 ： 18 of the ratio of solid and solution, 60% of ethanol concentration and microwave extracting for 50 seconds. Under these conditions, the extraction ratio of proanthocyanidin is 18.47 mg/g.
