摘要
相对于原淀粉，变性淀粉具有更广泛的用途和更多的应用领域。为了解国内变性淀粉专利技术的现状，以“中国专利数据库（知网版）”为数据源，用文献计量学方法，对1986～2014年有关变性淀粉的专利进行统计分析，结果表明，1986年，中国第一个变性淀粉专利申请；企业是申请变性淀粉专利技术最多的单位；变性淀粉应用最多的学科领域是化学和有机化工。
Modified starch has a wider range of use and application fields compared with native starch. In order to know about the present situation of patent technology of domestic modified starch, modified starch patents were analyzed ranging from 1986 to 2014 using the method of metrology, taking＂Chinese patent database （known network edition）＂as the data source. The results showed that the first Chinese modified starch patent was applied in 1986, companies were the most applicants for patent of modified starch, and modified starch was used mainly in the field of chemistry and organic chemical industry.
