Fabrication of sub-micron particles carrying food bioactive nanodroplets through multiple emulsions

One of the most important applications of W/O/W multiple emulsions is the encapsulation of sensitive watersolublecompounds (such as nutraceuticals and pharmaceuticals) to protect them against destructive factors and to controltheir release in different environmental. Nanodroplet of hydrophilic compounds produces by W/O microemulsion (5-100nm) can be covered by use of them as a primary emulsion in formulation of multiple emulsions. The coated ofnanoparticle of bioactive compound through sub- micron (>100nm) W/O/W emulsion can be protect and controllingrelease of them in different conditions. Food biopolymers, such as proteins and polysaccharide are among the hydrophilicemulsifiers which may be applied in external aqueous phase of W/O/W emulsions. Proteins by reducing the surf acetension between water and oil cause an emulsion to be highly stable.
