The formulation of emulsions for beverage applications has long been employed for cream liqueurs and flavour delivery systems. Dispersing a hydrophobic phase into an aqueous medium typically relies on the use of emulsification techniques having inherently high CO2 footprints stemming from both the processing methods and ingredients used. Commonly utilised processes such as high-pressure homogenisation are energy intensive processes that physically break-down oil droplets to a satisfactorily low diameter. Such droplets are stabilised via surface active ingredients including sodium caseinate from dairy, well known to successfully impart long term shelf stability. Successful advancement of the sustainability of emulsification technology (process and ingredients) will require meeting the droplet size, stability and physical properties of such beverages that drives their sensory perception in terms of mouthfeel and flavour.
This project will explore low energy emulsification techniques based on an appropriate combination of lipophilic, hydrophilic and surfactant phases requiring minimal mechanical energy input. Moving to lower environmental impact surfactants will require an in depth understanding of the role of such ingredients on the oil-in-water interface and the impact of such architecture on oral mucosa interactions and aroma release behaviour.
