High-internal-phase emulsion with stable chitosan hydrochloride as well as preparation method and application of high-internal-phase emulsion

The invention discloses a high internal phase emulsion with stable chitosan hydrochloride as well as a preparation method and application thereof, and the preparation method comprises the following steps: dispersing chitosan hydrochloride in water or an aqueous solution, standing, and preparing a chitosan hydrochloride solution with the mass percent concentration of 0.08-3% and the pH value of 5.7-12.7 as an aqueous phase; and shearing and mixing the water phase and the oil phase to obtain the high internal phase emulsion with stable chitosan hydrochloride, wherein the volume fraction of the oil phase is 74-91%. According to the method, the high internal phase emulsion can be efficiently prepared through one-step shearing dispersion only by independently using the chitosan hydrochloride without other surfactants or coagulators, a thought is provided for developing a novel emulsion stabilizer for the high internal phase emulsion, and the prepared high internal phase oil-in-water emulsion is green, safe, high i
