Microcapsule and preparation method and use thereof

Abstract

A microcapsule and a preparation method and use thereof are provided. The microcapsule includes a core phase and a shell phase with a volume ratio of (3.4-3.8):(0.8-1.2); wherein the core phase includes 8 wt % to 12 wt % of PVA, 4 wt % to 6 wt % of a density enhancer, 0.1 wt % to 0.3 wt % of an active substance, and a residual amount of water; the shell phase includes an elastomer precursor, a curing agent and silicone oil with a mass ratio of (9-11):(0.8-1.2):(2.5-3). The microcapsules of the present invention release active ingredients completely in milliseconds, and the release process exerts a relatively strong mechanical stimulation intensity on the surrounding environment which can further improve an absorption efficiency to the active ingredients in the fields of pharmaceuticals and cosmetics, and can provide a unique sensual experience in the field of food.
