The project outcomes will contribute to the mechanistic understanding of the lubrication behaviour of human oral mucosa.
Elizabeth Tenorio
PhD Student, My PhD project focusses on designing double emulsions stabilized by food grade particles. One of the primary purposes is to engineer low-fat foods to address global obesity challenges. As these food colloidal structures have to render similar characteristics to full-fat ones, tribological studies will be carried out to characterise and compare mouthfeel sensations using biomimetic oral set ups.
