Abstract
In composite particle production processes, simplification of process and composite morphology control are technical problems. In this study, NaCl-amino acid composite particles were prepared by atomizing crystallization method for the purpose of achievement of problems. The obtained composite particle had different composite morphology, such as distributed type and a surface-covering type for different combinations of solute materials. The morphology variation of the composite particles depends on the difference in crystallization rate and a habit modifier effect. As a result of calculating the solubility curve of pure solute into water, it turned out that the crystallization speed of sodium chloride was larger than amino acid. The distribution ratio of the water of sodium chloride is smaller than amino acid. It supports to be easy to dehydration.
