摘要
羧甲基淀粉钠(Sodium Carboxymethyl Starch,简称Na-CMS)又称羧甲基淀粉(CMS)或羧甲基淀粉醚,是一种冷水可溶性的阴离子型淀粉衍生物。为了改进以往用少量水和乙醇或是丙醇等混合溶剂醚化产率低、取代度相对较低的问题着手以甲醇为溶剂合成高粘度CMS。然而在发展的同时,也存在一些需要解决的问题,如甲醇对人体的侵害较为严重,大量使用不利于环境保护和人体健康,淀粉及深加工产品综合利用率低、深加工高科技产品少、淀粉转化率低等,缺乏针对性研究成了函待解决的问题。
Sodiunl carboxymethyl starch （Na - CMS, or CMS ） was a kind of cold water soluble anion starch derivative. In order to solve the problems like low yield etherification, relatively low degree of substitution with a small amount of water and ethanol or propanol, methanol was synthesized to high viscosity CMS. However, there were some problems that needed to be solved, such as methanol made the serious harm to human body and environmental, the low utilization of starch and deep - processed, the lack of relative high - tech products, the low rate of starch conversion, etc.
