Classification based on the structure of the system. General instability problems with emulsions : creaming/sedimentation, flocculation, Ostwald ripening, coalescence and phase inversion. Importance of emulsions in various industrial applications. Chapter 2 Thermodynamics of Emulsion Formation and BreakdownApplication of the second law of thermodynamics for emulsion formation : Balance of energy and entropy and non-spontaneous formation of emulsions. Breakdown of the emulsion by flocculation and coalescence in the absence of an emulsifier. Role of the emulsifier in preventing flocculation and coalescence by creating an energy barrier resulting from the repulsive energies between the droplets. Chapter 3 Interaction Forces between Emulsion DropletsVan der Waals attraction and its dependence on droplet size, Hamaker constant and separation distance between the droplets. Electrostatic repulsion resulting from the presence of electrical double layers and its dependence on surface (or zeta) potential and electrolyte concentration and valency. Combination of the van der Waals attraction with double layer repulsion and the theory of colloid stability. Steric repulsion resulting from the presence of adsorbed non-ionic surfactants and polymers. Combination of van der Waals attraction with steric repulsion and the theory of steric stabilisation. Chapter 4 Adsorption of Surfactants at the Oil/Water InterfaceThermodynamic analysis of surfactant adsorption and the Gibbs adsorption isotherm.

Описание: The migration of substances from packaging to food is a matter of concern for the food safety authorities, and packaging materials constitute a potential source of contaminants to which the consumer will be exposed to through their diet. A huge variety of substances can be present in packaging materials, which could consequently migrate into food and represent a risk to consumer health. Food Contamination by Packaging provides an overview of the main packaging contaminants including Bisphenol A, melamine, phthalates, alternative plasticisers, photoinitiators, perfluorochemicals, saturated and aromatic hydrocarbons (mineral oil saturated hydrocarbons and mineral oil aromatic hydrocarbons) from mineral oils, other bisphenol-related compounds, nanoparticles, primary aromatic amines and nonintentionally added substances. The analytical techniques used for their determination are reviewed. This book will be of interest to students and researchers in universities and research institutions associated with food packaging and, in general, to the food safety sector.

Описание: This book deals with adsorption and catalysis on the surface of transition elements and their compounds, many of which are in- teresting because of their particular electronic structure. Consideration is given mostly to simple (as opposed to mixed) oxides of transition elements, to common metals and to the adsorption of simple gases.
