| Abstract: | "Blooming" of tristearin (SSS), a spontaneous formation of flake-like surface structure on a triacylglycerols (TAG), was discussed. It has been well known that blooming of TAGs was closely related to the polymorphism, however, a foundamental question on how the blooming on micrometer scale was connected with the polymorphism on molecular scale is still unclear. We theoretically found that the flakes were formed to release deformation energy of surface induced 10 by phase transformation from the α-phase to the β'-phase in the polymorphism of SSS. It was also able to explain the flake size observed in experiments (~3μm × 3μm × 0.1μm). This theory would provide a better understanding of the spontaneous formation of surface structures in chocolate, fats, fatty acids, waxes, and water-repellent leaves of grasses. |
