Available in PDF, EPUB and Kindle. Book excerpt: Polymers are permeable, whilst ceramics, glasses and metals are gener ally impermeable. This may seem a disadvantage in that polymeric containers may allow loss or contamination of their contents and aggressive substances such as water will diffuse into polymeric struc tures such as adhesive joints or fibre-reinforced composites and cause weakening. However, in some cases permeability is an advantage, and one particular area where this is so is in the use of polymers in drug delivery systems. Also, without permeable polymers, we would not enjoy the wide range of dyed fabrics used in clothing and furnishing. The fundamental reason for the permeability of polymers is their relatively high level of molecular motion, a factor which also leads to their high levels of creep in comparison with ceramics, glasses and metals. The aim of this volume is to examine some timely applied aspects of polymer permeability. In the first chapter basic issues in the mathema tics of diffusion are introduced, and this is followed by two chapters where the fundamental aspects of diffusion in polymers are presented. The following chapters, then, each examine some area of applied science where permeability is a key issue. Each chapter is reasonably self-contained and intended to be informative without frequent outside reference. This inevitably leads to some repetition, but it is hoped that this is not excessive.

Download or read book Food Storage Stability written by Irwin A. Taub and published by CRC Press. This book was released on 1997-12-29 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food Storage Stability addresses one of the foremost problems faced by food processors - how to stabilize food once it is harvested. Using a holistic approach, the book discusses the changes responsible for food quality deterioration and considers strategies for minimizing or eliminating these degradative changes. Topics include: consumer perceptions and preferences, cellular changes, conversion of major constituents to more stable products, the effect of color and texture, packaging issues, and practical strategies for storing foods frozen, chilled, or at ambient temperature. Food Storage Stability is the only treatment of this subject that covers the diverse factors that influence quality retention in foods and integrates basic concepts in storage stability with practical applications. Food scientists and technologists concerned with changes in food quality are interested in ensuring that safe and appealing food products reach consumers - this is the book that will assist them with that important goal.
