摘要:
为实现对再造烟叶提取液成分的精确调控,将不同过滤精度膜依次用于提取液的分离,考察不同孔径膜及相应膜组合对提取液化学成分的截留效果影响。结果表明:孔径为200 nm的微滤(MF)膜主要截留悬浮物,孔径为20~30 nm的超滤(UF)膜可进一步截留可溶性蛋白质和果胶等大分子物质,孔径为5~10 nm纳滤膜(NF1)能够对烟碱和碳原子数介于10~13的烟草中性致香成分进行有效分离,而孔径为3~5 nm的纳滤膜(NF2)则对糖类物质和碳原子数6~8的中性致香成分具有较强的截留作用,孔径为1~2 nm的纳滤膜(NF3)可以截留有机酸盐和碳原子数超过4的中性致香成分;采用MF+UF+NF1+NF2+NF3膜分离组合方式能够实现对再造烟叶提取液主要化学成分的调控。
Abstract:
To achieve precise control of the components of the extracted liquid from reconstituted tobacco leaves, different filtration precision membranes were sequentially used for the separation of the extracted liquid, and the effects of different pore size membranes and corresponding membrane combinations on the retention of chemical components in the extracted liquid were investigated. The results showed that microfiltration(MF)membranes with a pore size of 200 nm mainly retained suspended solids, ultrafiltration(UF)membranes with a pore size of 20-30 nm could further retain macromolecular substances such as soluble proteins and pectin, nanofiltration membranes(NF1)with a pore size of 5-10 nm could effectively separate nicotine and tobacco neutral aroma components with carbon atom numbers ranging from 10 to 13, while nanofiltration membranes(NF2)with a pore size of 3-5 nm had strong retention effects on sugars and neutral aroma components with carbon atom numbers ranging from 6 to 8, and nanofiltration membranes(NF3)with a pore size of 1-2 nm could retain organic acid salts and tobacco neutral odorant components with more than 4 carbon atoms. The combination of MF+UF+NF1+NF2+NF3 membrane separation could be used to regulate the main chemical components of the reconstituted tobacco extract.
