摘  要:
以花生衣的原花色素提取液为原料,研究不同孔径的膜组件(NF-500、HPS-1、PS-5、PS-10)纯化原花色素提取液的效果。确定最佳纯化效果的膜组件,以及其不同操作压力、操作温度对纯化花生衣中原花色素得率和纯度的影响。结果表明:最佳纯化膜组件为HPS-1超滤组件,其操作压力0.54MPa,操作温度25℃,在此条件下,原花色素得率13.3%、纯度85.8%。

摘  要:
The proanthocyanidin-rich extract from peanut skin was purified and condensed by membrane separation technique. The purification effects of membrane modules with different pore sizes (NF-500,HPS-1,PS-5 and PS-10) on the extract were assessed. Collectively considering product yield and purity,the optimal purification conditions were using HPS-1 module at a trans-membrane pressure of 0.54 MPa and an operating temperature of 25 ℃. Under such purification conditions,the yield and purity of purified proanthocyanidin were up to 13.3% and 85.8%,respectively.
