Practicing the natural polymer materials with functional oil or oil-soluble core material, to format a small vesicle, which is a kind of oil-in-water (O/W) structure. According to the chemical and physical characteristics of various functional implications and the customized necessities of customers. HSF targets different studies and screens to build up suitable materials and linking agents. Those practices can realize the scientific embedding of functional substances, particularly enhancing the taste, shielding the odor, improving the oxidation stability, improving the mechanical resistance, accelerating the dissolution, accurate control of slow release, scientific targeted release, and efficient directional absorption.
