Method for judging activeness of daqu worms based on content of 1-pentadecene substance

The invention relates to the technical field of koji insect activeness detection, in particular to a method for judging koji insect activeness based on 1-pentadecene substance content, which comprises the following steps: (1) weighing a koji sample, adding an extraction solvent into the koji sample, and leaching to obtain a leaching solution; feeding the leach liquor into a gas chromatograph-mass spectrometer to detect the content of 1-pentadecene; and (2) judging the activeness of the daqu worms according to the 1-pentadecene content detected in the step (1). According to the method, the koji insect activeness of the yeast sample can be more accurately judged, and meanwhile, the time for detecting the koji insect activeness of the yeast sample can be greatly shortened. 本申请涉及曲虫活跃度检测技术领域，具体涉及一种基于1-十五烯物质含量评判大曲曲虫活跃度的方法，包括以下步骤：(1)称取大曲样品，向所述大曲样品中加入提取溶剂浸提，得到浸提液；将所述浸提液送入气相色谱质谱联用仪检测1-十五烯含量；(2)根据所述步骤(1)检测的所述1-十五烯含量评判大曲曲虫活跃度。本申请能够更加准确的评判大曲样品的曲虫活跃度，同时能够大幅缩短检测大曲样品曲虫活跃度的时间。
