Lipids Physics

The functionality of fats, oils and surfactants is a direct function of the nanostructure, microstructure and intermolecular interactions at play in such materials. This in turn, is a complex function of molecular structure and phase/state behavior, both under equilibrium and nonequilibrium conditions. Knowledge of the physics and physical chemistry of fats, oils and surfactants and its relationship to functionality and properties has become particularly important due to public and government pressure to eliminate trans fats while reducing saturated fat in food products, as well as to find more "natural" surfactants. Knowledge of the structure and self-assembly properties of polar lipids is important in the understanding of biomembrane structure and the formation of different lipid mesophases. This has implications for human health as well as the design of novel encapsulation/delivery systems for foods, pharmaceuticals, nutraceuticals and cosmetic products. The purpose of the Lipid Physics library is to create a repository of much-needed physical properties data as well as to cover different aspects of the physical characterization of lipidic materials. Selected theory topics will also be provided in order to enhance and supplement analytical and product development efforts in this area.
