Association colloids as delivery systems: principles and applications in the food and nutraceutical industries
E.J. Acosta, University of Toronto, Canada
Surface active molecules such as polar lipids and surfactants self-assemble into association colloids that include micelles, liquid crystals and microemulsions that are used to design delivery systems for nutraceuticals, vitamins and minerals. The first part of the chapter provides a general overview of lipid absorption and the role of bile salt micelles and lipoprotein assemblies in the process, as an example of how nature uses association colloids. The second part of the chapter summarizes the thermodynamic principles and main features of the phase behavior leading to the ...
