摘要
利用紫外光图谱（λ=200-400nm）分析糖厂甘蔗汁中各种酚类物质、有机酸及其还原糖分解物对蔗汁色值的影响。结果表明：在弱酸性的蔗汁中，加入适量的碱性阳离子物质，可以吸附已经离解的酚类物质，从而提高蔗汁的澄清效果。
The effect of phenolics, organic acids and decomposers of reducing sugar on the color values of sugarcane juice was studied by ultraviolet spectrum （λ=200-400 nm） method. Result indicated that the addition of basic cation substance could improve the clarification of sugarcane juice, because of the basic cation substance can adsorb the phenolics in sugarcane juice.
