Abstract
Although the measurement of oil globule size distribution is necessary to detect the process of demulsification, the reasonable methodology for its measurement has not been suggested because the solution of soymilk contains insoluble soybean particle and the protein to interfere with the detection of oil globule or oil content. The oil globule size distribution was measured by the homogeneous suspension and cumulative method under gravitational force or centrifugal force, which were modified with Stokes' low. The geometric mean diameter of oil globules in this soymilk was
두유에는 기름의 양이나 입도를 분석하는데 장해를 주는 대두단백질, 미세한 대두입자들이 공존하고 있어서 기존의 microscopic image analysis, coulter counter, 또는 Photo-analysis 등의 사용이 많은 문제점을 노출했다. 본 실험에서 Stokes 법칙을 응용하여, 중력장과 원심력장하에서 homogeneous suspension과 cumulative method를 이용하여 입도분포를 분석했다. 선정된 두유에서 기하학적 평균지름은 중력장하에서는
