Event details

Organogels have been identified as a possible means of replacing saturated fats from foods. One of the most interesting edible organogel systems is that of the phytosterol β-sitosterol and phytosterol ester γ-oryzanol. These plant extracts have been shown to form extremely solid like gels in sunflower oil, but the molecular interactions underpinning the gelation process are poorly understood, and the gel tends to break down in the presence of water. This has proven to be a significant barrier to the wide-spread incorporation of these gels into foods. In this talk, I will discuss our ongoing work to better understand the competing molecular interactions which drive the formation of these gels, identify other molecules which self-assemble in a similar manner, and possible strategies to form emulsions with these gels whilst mitigating the effects of water.

About Condensed Matter lunchtime seminars

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
