| 摘 要： | 目的：从产业化角度将膜过滤技术应用于黑米花青苷色素生产过程，以提高黑米花青苷色素产品的纯化效果和产率，改善其在酒、饮料等中的应用特性。方法：分别采用截留量2000kD和1000kD的陶瓷膜，脱除黑米花青苷色素提取液中的脂溶性成分；采用截留分子质量100D的纳滤膜对脱脂后的黑米花青苷色素液进行浓缩。考察膜处理前后黑米花青苷色素色价值、脂溶性成分含量、干物质和酒精度等指标的变化情况。结果：结果表明，截留量1000kD陶瓷膜对黑米花青苷色素液的脱脂效果优于截留量2000kD的陶瓷膜；截留分子质量100D的纳滤膜能达到预期的浓缩要求。结论：截留量1000kD陶瓷膜和截留分子质量100D的纳滤膜可用于黑米花青苷色素的产业化生产。

| Abstract: | Objective:To improve the pruification efficiency and the yield of anthocyanins from black rice as well as its application charactersitics in wine and beverage by using membrane technique during the production of anthocyanins.Methods:Two kinds of ceramic membranes with molecular weight cut off(MWCO) of 2000 kD and 1000 kD,respectively,were used for the degrease of black rice.Meanwhile,one kind of nanofiltration membrane with MWCO of 100 D was used for the extraction of anthocyanins from degreased black rice.Results:The ceramic membrane with MWCO of 1000 kD revealed better degreasing effect than that of ceramic membrane with MWCO of 2000 kD.Moreover,the nanofiltration membrane with MWCO of 100 D could meet expected requirements during condensation process.Conclusion:The ceramic membrane with MWCO of 1000 kD and nanofiltration membrane with MWCO of 100 D can be used for industrial production of anthocyanins from black rice. |
