Stability and Release Behavior of Bioactive Compounds (with Antioxidant Activity) Encapsulated by Pickering Emulsion

Colloidal based delivery systems are gaining tremendous attentions in the food and pharmaceutical industries to encapsulate, safeguard and deliver a wide range of bioactive compounds. These formulations predominantly include nano, micro or particle stabilized Pickering emulsions (PEs). Among them, PEs which are emulsions stabilized by solid particles instead of surfactants are regarded as better choices due to their long term and non-toxic nature. The current chapter is mainly focused on the formulation of these PEs using different kinds of stabilizers (to stabilize the oil/water interfaces) derived from inorganic and organic (e.g. polymers, proteins, fats, etc.) sources. Thereafter, different factors relating to the formation and influencing the stability and hence the quality of the PEs were discussed. Finally, the vital roles of PEs as a delivery vehicle for various bioactive compounds with potential antioxidant activity have been highlighted in details.
