I am very honored to have received the OGS -OAC 58 award, based on my research into the replacement of saturated fats with healthier alternatives. (See below.)

Summary of research:
One of the main challenges in fats and oils research is the replacement of saturated fats with healthier alternatives.  A material designed for this purpose is an oleogel- a gel made out of liquid oil.  To make an oleogel, a specific gelling molecule (the gelator) is added to oil and self-assembles, forming a network and trapping the liquid.
My research focuses on ethyl cellulose (EC) oleogels, gels formed by interactions between ethyl-substituted cellulose strands.  Although these gels have been physically characterized and researched for their application in food and cosmetic products, their breakdown under digestion conditions has not been explored.  I am looking at EC oleogel digestion using an in-vitro model mimicking oral, gastric and intestinal phases.  EC gels are made using different molecular weight polymers at varying concentrations and their digestibility through time is monitored.  The release of beta-carotene, a lipid-soluble molecule, from the gel is also measured.
This research has potential applications in food product development, nutraceutical and lipid-soluble drug delivery.
