Micro encapsulation is a useful tool to protect active ingredients in a formulation from the environment. Responsive micro-capsules can be used to deliver active ingredients and release them at a specific location, or time. Release can be triggered by an external stimuli such as a change in pH or temperature. I will present two micro-encapsulation systems for hydrophilic actives. All components are food grade and they are designed for use as a food-based delivery system. I will discuss their manufacture, factors affecting encapsulation efficiency and preliminary work on release properties.
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..
