Proteins serve as an important nutritional as well as structural component of foods. Not only do they provide an array of amino acids necessary for maintaining human health but also act as thickening, stabilizing, emulsifying, foaming, gelling, and binding agents. The ability of a protein to possess and demonstrate such unique functional properties depends largely on its inherent structure, configuration, and how they interact with other food constituents, like, polysaccharides, lipids, and polyphenolic compounds. Proteins from animal sources have superior functionality, higher digestibility, and lower anti-nutrient components than plant proteins. However, consumer preferences are evolving w...
The quality and safety of the food we eat deserves the utmost attention and is a priority for producers and consumers alike. Shelf life studies provide important information to manufacturers and consumers to ensure a high-quality food product. Various evaluation methods are used for shelf life determination and they are usually performed at the manufacturer level. Moreover, various techniques are utilized throughout the food chain that enhance the shelf life of food products. This sensitive issue is reviewed in Shelf Life and Food Safety, which brings together a group of subject experts to present up-to-date and objective discussions on a broad range of topics including food spoilage and saf...
A fundamental understanding of polymers has evolved in recent years concurrent with advances in analytical instrumentation. The theories and methodologies developed for the galacturonan biopolymers (collectively called pectins) have seldom been discoursed comprehensively in the context of the new knowledge. This text explains the scientific and technical basis of many of the practices followed in processing and preparing foods fabricated with or containing pectin. The material is presented in a very readable fashion for those with limited technical training. - Structural analysis - Commercial extractions methods - Pectin formulations and tropical fruit analysis - Molecular mechanisms of gelatin - Enzymology - Polymer comformation techniques - Analytical methods of polymer analysis
Preservation of Foods with Pulsed Electric Fields discusses the basics of high voltage PEF as a low temperature food processing method, and the application of this technology in food preservation. This technology is attracting a great deal of interest around the world because it is more cost effective than conventional systems due to the conservative nature of PEF. This book thoroughly covers the electrical and food engineering aspects, as well as the food science components (i.e. food microbiology, enzyme inactivation kinetics, and sensory evaluation). - Fundamentals of high intensity pulsed electric fields - Design of PEF processing equipment - Biological principles for microbial inactivation in electric fields - PEF-induced biological changes - PEF inactivation of vegetable cells, spores, and enzymes in foods - Food processing by PEF - HACCP in PEF processing - PEF in the food industry for the new millennium
Comprehensive in scope, Food Polysaccharides and Their Applications, Second Edition explains the production aspects and the chemical and physical properties of the main classes of polysaccharaides consumed as food, highlighting their nutritional value and their technological characteristics. Chapters in this new edition detail the source,
Reflecting current trends in alternative food processing and preservation, this reference explores the most recent applications in pulsed electric field (PEF) and high-pressure technologies, food microbiology, and modern thermal and nonthermal operations to prevent the occurrence of food-borne pathogens, extend the shelf-life of foods, and improve
This book presents important developments in green chemistry, with a particular focus on composite materials chemistry. In recent years, natural polymers have generated much interest due to their unique morphology and physical properties.

A comprehensive overview of different antimicrobial polymeric materials, their antimicrobial action modes and applications.
Abstract: Advances in the techniques and methodologies for the evaluation of protein quality are presented for agricultural researchers. An overall view of the strengths and weaknesses of the various evaluation methods is provided along with in-depth descriptions of several new and established techniques. The discussions cover the protein requirements of humans and their relevance to protein quality evaluation, the analytical methods for determining the amino acids profiles of particular foods, chemical and microbiological assays of protein quality, use of animal experimentation and clinical methods, and choice of procedure. The specific methodologies described include the Kjeldahl procedure for total nitrogen determination, sulphur amino acid analysis by performic acid pre-oxidation, the four-enzyme in vitro assay for protein digestibility, and procedures for the determination of net protein utilization and relative protein value in rats.
