Feedstuff Evaluation contains the proceedings of the 50th University of Nottingham Easter School in Agricultural Sciences, held at Sutton Bonington in July 1989. The book presents papers discussing a wide range of topics on the accurate evaluation of feedstuffs for livestock. Initially, systems of expressing the nutritive value of feeds are considered. Modifications to feeding value as influenced by animal factors including intake and palatability are discussed. Specific dietary ingredients, being plant polysaccharides, fats, minerals and vitamins are detailed. Prediction of the nutritive value of compound feeds and individual feeds through classical wet chemistry and the more recent NIR is assuming considerable importance in the rapid evaluation of diets. Associated with these developments is an appreciation of the relevance of both inter- and intra-laboratory variation in determinations. Finally, the need to collate information into an interactive data-base is being actively pursued. It is evident that safety of animal feeds is becoming an increasingly topical issue and the last session considered the relevance of naturally-occurring toxic factors, residues, mycotoxins and, finally, animal pathogens. Veterinarians, farmers, farm administrators, and those involved in every aspect of nutrient supply to animals will find the compendium very insightful and informative.

This volume illustrates significant changes in optical, magnetic, ultrasonic, mechanical and biological nondestructive evaluation techniques for online automatic control of food quality evaluation, including X-ray tomography. It presents advances in computer vision, X-ray imaging, ultrasonics, biosensors, and data analysis.

Sensory evaluation is a scientific discipline used to evoke, measure, analyse and interpret responses to products perceived through the senses of sight, smell, touch, taste and hearing. It is used to reveal insights into the way in which sensory properties drive consumer acceptance and behaviour, and to design products that best deliver what the consumer wants. It is also used at a more fundamental level to provide a wider understanding of the mechanisms involved in sensory perception and consumer behaviour. Sensory perception of products alters considerably during the course of consumption/use. Special techniques are used in product development to measure these changes in order to optimise product delivery to consumers. Time-Dependent Measures of Perception in Sensory Evaluation explores the many facets of time-dependent perception including mastication and food breakdown, sensory-specific satiety and sensory memory. Both traditional and cutting-edge techniques and applications used to measure temporal changes in sensory perception over time are reviewed, and insights into the way in which sensory properties drive consumer acceptance and behaviour are provided. This book will be a valuable resource for sensory professionals working in academia and industry, including sensory scientists, practitioners, trainers and students; and industry-based researchers in QA/QC, R&D and marketing.

Containing 45 papers written by outstanding international authors from 14 countries, this three-volume compendium brings together the elements needed to understand the factors which influence the utilization of amino acids. The wide-ranging topics include descriptions of metabolic pathways and mechanisms of the biological utilization of amino acids, as well as factors that influence amino acid bioavailability in enteral and parenteral nutrition. The use of amino acids to improve the quality and safety of the diet is presented. Also discussed are amino acid precursors of biogenic amines and the role of amino acids in atherosclerosis, cancer, and immunity. Scientists from many disciplines will benefit from this broad overview.

This book is an accessible, contemporary, and comprehensive guide to the concepts and practice of evaluation. Authors Gail Vallance Barrington and Beverly Triana-Tremain integrate new approaches and concerns, and classic frameworks with practical tools that readers can use to design evaluation studies. They show how evaluators measure whether the planned and implemented interventions or services are achieving their goals and objectives, while focusing on the questions most important to the community and organizations in which the evaluation takes place. The book stresses the role of critical and evaluative thinking, as well as self-reflection, and demonstrates the importance of context and equity in today’s turbulent environment, offering a new stance for evaluators to support global as well as local issues.
