摘 要: 研究多种非糖物质同时存在时的蔗糖分解问题。结果表明,在酸性条件下,影响蔗糖分解反应速度常数K的显著因素是pH、温度以及二者的交互作用,非糖组分的影响作用不显著;而在碱性条件下(pH9~11),蔗糖的分解反应速度很小,主要是还原糖破坏,产生有机酸和色素.论文还对这些研究结果进行了机理探讨. Decomposition of sucrose was studied with various of non-sugars. It was found that there is a remarkable influence of pH,temperature and their mutual effects on the velocity constant K of sucrose decomposition under the acid condition, but not of non-sugars. Under the condition (pH9 ~ 11 ),sucrose is not nearly decomposed,and only reducing sugar is disructed to produce organic acids and colourants.Finally the mecanism of sucrose decompositon was briefly discussed.
