This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A selected rainbow trout strain was used as a model to identify physiological parameters associated with improved performance when fed all plant-protein feed. Results from a digestibility trial showed that selection had no measurable effect on apparent digestibility coefficients of nutrients in the all plant-protein or a conventional fishmeal-based diet. While this result validated apparent digestibility as an evaluation tool for ingredient and diet quality, it demonstrated that other physiological mechanisms are responsible for the improved performance of the selected strain when fed an all plant-protein, high-soy diet. A subsequent experiment was conducted to evaluate the effects that alternate protein ingredients and plant protein mixtures with or without amino acid supplementation have on trout digestive physiology. Results from temporal plasma amino acids measurements at the absorption site (hepatic portal vein) and from the systemic blood (caudal vein) demonstrated that plasma amino acid level in the hepatic portal vein, measured at intervals following a single meal, are a valuable tool to evaluate the effects of candidate alternate proteins on fish digestive physiology. The findings showed that each ingredient affects digestive physiology of the fish in a singular manner when ingredients are fed individually. However, they do not have any predictable additive effect when fed together as a mixture. Moreover, the addition of crystalline amino acids to an all-plant protein mixture altered the plasma concentrations of all the amino acids as it did for uptake reflected in the hepatic portal vein. A major finding in the study was that the selected trout strain fed the plant protein mixture with amino acid supplementation showed a noteworthy difference compared to an unselected strain, specifically, a synchronous and homogenous decreasing pattern for all the essential amino acids over time in the hepatic portal vein. This indicates that homogeneous dietary amino acid uptake in the hepatic portal vein and rapid postprandial plasma amino acid disappearance are results of nutritional adaptation driven by selection for growth on and tolerance of all-plant protein diet. Results from gene expression of amino acid transporters, cholecystokinin and genes related with protein and amino acid metabolism supported the findings from the plasma amino acids. In conclusion, the results of the research described in this dissertation demonstrated that improved performance of the selected trout strain is associated with synchronous protein digestion of the plant protein mixture and synchronization of amino acid absorption leading to improved amino acid availability and utilization.

Download or read book Applied Food Protein Chemistry written by Zeynep Ustunol and published by John Wiley & Sons. This book was released on 2014-12-19 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food proteins are of great interest, not only because of their nutritional importance and their functionality in foods, but also for their detrimental effects. Although proteins from milk, meats (including fish and poultry), eggs, cereals, legumes, and oilseeds have been the traditional sources of protein in the human diet, potentially any proteins from a biological source could serve as a food protein. The primary role of protein in the diet is to provide the building materials for the synthesis of muscle and other tissues, and they play a critical role in many biological processes. They are also responsible for food texture, color, and flavor. Today, food proteins are extracted, modified, and incorporated into processed foods to impart specific functional properties. They can also have adverse effects in the diet: proteins, such as walnuts, pecans, almonds, and cashews, soybean, wheat, milk, egg, crustacean, and fish proteins can be powerful allergens for some people. Applied Food Protein Chemistry is an applied reference which reviews the properties of food proteins and provides in-depth information on important plant and animal proteins consumed around the world. The book is grouped into three sections: (1) overview of food proteins, (2) plant proteins, and (3) animal proteins. Each chapter discusses world production, distribution, utilization, physicochemical properties, and the functional properties of each protein, as well as its food applications. The authors for each of the chapters are carefully selected experts in the field. This book will be a valuable reference tool for those who work on food proteins. It will also be an important text on applied food protein chemistry for upper-level students and graduate students of food science programs.
Download or read book Improving Farmed Fish Quality and Safety written by Øyvind Lie and published by Elsevier. This book was released on 2008-08-20 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global aquaculture production has grown rapidly over the last 50 years. It is generally accepted that there is limited potential to increase traditional fisheries since most fish stocks are well or fully exploited. Consequently increased aquaculture production is required in order to maintain global per capita fish consumption at the present level. Fish farming enables greater control of product quality and safety, and presents the possibility of tailoring products according to consumer demands. This important collection reviews safety and quality issues in farmed fish and presents methods to improve product characteristics.The first part of the book focuses on chemical contaminants, chemical use in aquaculture and farmed fish safety. After an opening chapter discussing the risks and benefits of consumption of farmed fish, subsequent contributions consider environmental contaminants, pesticides, drug use and antibiotic resistance in aquaculture. Part two addresses important quality issues, such as selective breeding to improve flesh quality, the effects of dietary factors including alternative lipids and proteins sources on eating quality, microbial safety of farmed products, parasites, flesh colouration and off-flavours. Welfare issues and the ethical quality of farmed products are also covered. The final part discusses ways of managing of product quality, with chapters on HACCP, monitoring and surveillance, authenticity and product labelling.With its distinguished editor and international team of contributors, Improving farmed fish quality and safety is a standard reference for aquaculture industry professionals and academics in the field. Reviews safety and quality issues in farmed fish and presents methods to improve product characteristics Discusses contaminants, persistent organic pollutants and veterinary drug residues and methods for their reduction and control Addresses important quality issues, genetic control of flesh characteristics and the effects of feed on product nutritional and sensory quality
Download or read book Fish Energetics written by Peter Tytler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
