Buch. Zustand: Neu. Neuware - Food Colloids: Interactions, Microstructure and Processing describes the principles and practice underlying the formulation of food emulsions, dispersions, gels, and foams. Emphasis is on understanding how the functional properties of biopolymers and surfactants determine the texture and shelf-life of multiphase food materials.This book provides essential new findings by experts in the field on specific topics including: the interfacial rheological properties of proteins; the use of microscopy and image analysis to probe structure and phase transitions; the control of colloidal stability during thermal and mechanical processing; the interactions of proteins with polysaccharides and emulsifiers; the incorporation of neutraceuticals into food colloids; and the consumer perception of taste and texture.Food Colloids: Interactions, Microstructure and Processing provides a link between current research on the fundamental physical chemistry of colloidal systems and the requirements of the food technologist to use modern colloid science in new product formulation. It is suitable for postgraduates and researchers, both in industry and academia.

Buch. Zustand: Neu. Neuware - Chromatography is a major analytical technique that is used throughout research, development and manufacturing in the pharmaceutical, medical device and associated industries. To demonstrate fitness for purpose with the applicable regulations, the systems must be validated.Validation of Chromatography Data Systems introduces the basics of computer validation. It looks in detail at the requirements throughout the life cycle of a CDS for any regulated laboratory, from its concept, through writing the user requirements specification to selecting the system, testing and operational release, including using electronic signatures. This logical and uniquely organised book provides the background to the regulatory requirements, interpretation of the regulations and documented evidence needed to support a claim that a system is validated. Development of the system, risk management, operation and finally system retirement and data migration are discussed. Case studies and practical examples are provided where appropriate.Validation of Chromatography Data Systems is ideal for the chromatographer working in analytical laboratories in the regulated pharmaceutical, contract research, biotechnology and medical device industries seeking the practical guidance required for validating their chromatography data systems in order to meet regulatory requirements. It will also be welcomed by consultants or those in regulatory agencies.
