China H&Z® Vitamin A acetate is an unsaturated ester, oily, easy to oxidize, soluble in fat or organic solvents, but insoluble in water, and difficult to be added evenly to food. So the application range is limited. After microencapsulation , Can improve its water solubility and stability, and its form changes from oily to powdery, which is convenient for storage and transportation and processing.
