摘要

溶解性能是粉粒状物质的一个重要理化指标，但在测量过程中由于细小微粉易结“团块”并黏附在器壁或搅拌桨上，会影响测量结果。本研究自行设计了一个新的实验装置，以水分散液色度作为监控指标，可以准确地测定微囊化β-胡萝卜素干粉在水中的溶解性能。通过分析其溶解动力学和溶解活化能，找出了其溶解行为的限速因子，并提出了改善其溶解性能的对策，对优化微囊化β-胡萝卜素干粉的配方具有很好的指导意义。

Abstract

Dissolution characteristics is an important index for soluble powder

however

the experimental results are always irreproducible because of the fine powder’s lump-formation or conglutination tendency.In this work

a simple apparatus for determining the dissolution properties of soluble β-carotene powder was designed and set up to resolve these problems.Through monitoring the increase in solution chroma

the dissolution characteristics of two kinds of microencapsulated β-carotene powder in water were investigated

and a parameter for the deliquescent portion was determined as a function of time.Relative dissolution curves were plotted and dissolution kinetics as well as dissolution activation energy were analyzed.Based on the key factors for powder dispersion or dissolution obtained

this method can be used to improve the dissolution abilities.
