Study on Dispersion of Oils and Fats in “Cluster-Water”

Oxygen-17 nuclear magnetic resonance spectra of “cluster-water, ” prepared by Hattori's method, and of commercially purified water were measured. It was found that the half-height widths of the 17O-signals for “cluster-water” and commercial water are 56.3 and 142.4Hz, respectively. The result implies that the average size of clusters in “cluster-water” is smaller than that in commercial water. The degree of dispersion for colloidal samples of triolein, oleic acid and monoolein dispersed in “cluster-water” and in purified water was investigated by proton nuclear magnetic resonance. The degree of dispersion of the samples dispersed in “cluster-water, ” was found to be greater than that for the samples dispersed in commercial water. Thus, it was assumed that the average size of water-clusters and the difference in dynamic structure between the water samples affect the degree of dispersion of oils and fats in water.
