Detection method of amylase

The present invention discloses a detection method of amylase. A principle of the detection method is as follows: after a sample to be detected and starch are mixed, the mixture is dissolved in water,the dissolved mixture is stained with a potassium iodide-iodine solution, morphology of starch granules is observed under a microscope, and morphological changes of the starch granules are used to determine whether the sample to be detected contains the amylase. If the starch granules swell significantly, become lighter in color or disappear, the sample to be detected contains the amylase. If themorphological changes of the starch granules are not shown, the sample to be detected is free of the amylase. The provided detection method is simple and convenient to operate, intuitive and easy tounderstand in results, high in detection precision, simple in sample processing and small in required sample amount. 本发明公开了种淀粉酶的检测方法，该检测方法的原理是以待测样品和淀粉混合后溶解在水中，用碘化钾-碘溶液染色，在显微镜下观察淀粉颗粒的形态，通过淀粉颗粒的形态变化判断待测样品中有无淀粉酶。若淀粉颗粒明显膨胀、颜色变浅或颗粒消
