In my current research I am working with development of formulations for encapsulation of bioactive compounds (vitamins and protein) and bacteria in the form of emulsions and microspheres and looking into different aspects of these formulation including:

  • Characterization of the physical and encapsulations properties
  • Characterization of encapsulation stability during storage and simulated in vitro digestion



Solid particles can be used to stabilize emulsions, where they create a category of emulsions known as Pickering emulsions. Recently, health and environmental concerns have led to new market demand for natural, biodegradable and renewable sources of ingredients. Starch granules meet these ingredient requirements and are also good candidates for stabilization of Pickering type emulsions.

This PhD project tries to investigate different aspect of Pickering emulsions stabilized by starch granules some of which are summarized in the following points:

  • Isolation, modification and characterization of starch as Pickering particles
  • The preparation and properties of oil-in-water emulsions stabilized by starch granules
  • The process and encapsulation stabilities of the emulsions in the context of simple oil-in-water and double water-in-oil-in-water emulsions
  • The physical and encapsulation stabilities of the emulsions during processing as well as simulated in vitro digestion
