    • This invention provides a method for rapidly measuring an premature yeast flocculating factor of malt contained in a brewing material, comprising the following steps of: (1) mixing yeast in the late logarithmic growth phase or thereafter with a water-extracted high molecular fraction prepared from a test material sample in a buffer solution and suspending the mixture in the buffer solution; and (2) irradiating the suspension obtained in the step (1) with visible light, photographing the scattered light with a camera device, image-analyzing the image data thus obtained and determining the degree of whiteness of the suspension to measure the degree of sedimentation of the yeast in the suspension. According to the present invention, the premature yeast flocculating factor of malt contained in the brewing material can be measured in a highly accurate, rapid and simple manner, and, further, even a plurality of analytes can be rapidly measured.
    • 本发明提供了一种用于快速测量酿造材料中所含的麦芽过早的酵母絮凝因子的方法,包括以下步骤:(1)将晚期对数生长期或其后的酵母与由水提取的高分子级分混合制备, 将缓冲溶液中的测试材料样品悬浮在缓冲溶液中; 和(2)用可见光照射步骤(1)中获得的悬浮液,用相机装置拍摄散射光,对如此获得的图像数据进行图像分析,并确定悬浮液的白度以测量沉降程度 的酵母在悬浮液中。 根据本发明,可以以高精度,快速和简单的方式测量酿造材料中所含的麦芽过早的酵母絮凝因子,并且甚至可以快速测量多种分析物。
