摘要
This invention provides a method for rapidly measuringan premature yeast flocculating factor of malt contained in abrewing material, comprising the following steps of: (1) mixingyeast in the late logarithmic growth phase or thereafter with awater-extracted high molecular fraction prepared from a testmaterial sample in a buffer solution and suspending the mixturein the buffer solution; and (2) irradiating the suspensionobtained in the step (1) with visible light, photographing thescattered light with a camera device, image-analyzing the imagedata thus obtained and determining the degree of whiteness ofthe suspension to measure the degree of sedimentation of theyeast in the suspension. According to the present invention,the premature yeast flocculating factor of malt contained in thebrewing material can be measured in a highly accurate, rapidand simple manner, and, further, even a plurality of analytescan be rapidly measured.
