Project title: Microbrewidics: Creating stable hop oil emulsions using microfluidic technology

Department: Chemistry

Faculty supervisor: Dr. Katherine Elvira

"In collaboration with Phillips Brewing and Malting Co., the goal is to push the boundaries of hop flavour and gain selective control over the hop essential oils that are integrated into the complex flavour matrices found in beers. This will also enable more accurate predictions of flavour degradation during distribution. Emulsion formation and visualisation is performed using microfluidic devices to determine the hop emulsion characteristics that provide the most stable flavour profile in beer. These lab-on-a-chip platforms use plastic chips designed to include features such as pipes and valves to create oil-in-water emulsions, and the individual droplets that create the emulsion can then be visualised and quantified both on- and off-chip."
