Meanwhile, the method utilizes the amphiphilic emulsification effect formed by the hydrogenated palm oil and the sodium starch octenyl succinate on the outer wall of the magnesium oxide, thereby reducing the sedimentation speed of the magnesium oxide in emulsion suspension and improving the processing performance of the magnesium oxide in the food industry.
3) According to the microencapsulated magnesium oxide provided by the application, the magnesium oxide microcapsule is prepared by using a spray drying method, and the obtained capsule can solve the problem that magnesium oxide is easy to precipitate in brewing products.
