用膜过滤技术提高液体香精澄清度的应用研究与工业化装置

The Study and Industrial Device for Improving the Limpidity of the Liquid Flavors by Using Membrane Filter Technique

液体食用香精在配制工序的搅拌过程中,各种成分相互溶解、混和;在物理、化学反应的作用下造成香精成品混浊的现象可以借助于膜过滤技术处理到清澈的状态。膜过滤器的膜孔尺寸,膜材的表面性质对处理效果存在显著的影响,其中磺化聚醚砜膜适用于处理油质香精。

In the mixing or stirring process for liquid flavors formulating, there are dissolution, mixture and other physical and chemical reactions happened among various ingredients, which may caused the turbidity of the final produce. This kind of turbidity mass can be treated into clear by the membrane filter technique. The filtering effectiveness can be affected by the size of the apertures on the membrane and the surface property of the membrane materials. The Polyethersulfone is suited to the oily flavors.
