玉米中淀粉含量的测定方法有很多，GB/T 5514—2008标准中规定采用酶水解法对玉米中的淀粉含量进行测定，但该方法存在结果偏低、偏差较大的缺点。本实验对标准中的实验方法及相关条件，如玉米称样量、加水量、液化酶用量、液化温度、液化时间、水浴条件、过滤方式、加酸量等，进行了优化并对实验中存在的问题进行了分析和探讨，优化后的方法适合玉米中淀粉含量的测定，具有实用、准确、稳定性好的特点。

There are many methods for the measurement of starch content in corn. GB/T 5514-2008 provides that enzyme hydrolysis method is adopted for the measurement of starch content in corn. However, such method has the disadvantages such as comparatively low measuring re-sults and comparatively high deviations. In this study, the related technical parameters in enzyme hydrolysis method (sample weight, water add-ing level, the use level of liquefied enzyme, liquefying temperature, liquefying time, water bathing conditions, filtration modes, acid adding lev-el etc.) were explored and further optimized. After technical optimization, enzyme hydrolysis method was suitable for the measurement of starch content in corn and it had the features such as practical, high-accuracy, and good stability.
