Heat-resistant and shear-resistant microcapsule, and preparation method therefor and use thereof

Abstract

A heat-resistant and shear-resistant microcapsule includes a core material, a protein wrapping layer wrapping the core material, and a wall material wrapping the protein wrapping layer. The core material includes grease. The wall material is formed by heating and curing a colloid. According to the microcapsule, first, an internal environment in which moisture and oxygen are isolated is provided by wrapping internal phase grease with a protein, and the survival rate and stability of active substances in a heat treatment process are improved by means of heat absorption in phase change at melting points; then, the wall material is used for further protection, so that the microcapsule has relatively high stability, has relatively strong shear resistance while having high temperature resistance, and also has relatively high acid resistance.
