Extraction method of cereal heat-resistant lipase

The invention discloses an extraction method of cereal heat-resistant lipase, and relates to the technical field of biological extraction. The extraction method comprises the following steps: (1) performing high-temperature stabilization treatment on cereal bran to obtain stabilized bran; and (2) extracting the stabilized bran by using a solution containing a surfactant to obtain the grain heat-resistant lipase. The extraction method disclosed by the invention has the advantages that (1) the heat-resistant lipase can be extracted from the stabilized bran by adding the surfactant into the buffer solution; and (2) the extracted lipase has good heat resistance, and the extraction method is simple. The invention provides theoretical basis guidance for discussing the enzymological characteristics of grain heat-resistant lipase, enriching the types of grain endogenous lipase and researching and developing a grain bran efficient and stable processing technology. 本发明公开了一种谷物耐热脂肪酶的提取方法，涉及生物提取技术领域。该提取方法包括以下步骤：(1)将谷物糠麸进行
