Extraction is an important operation in food engineering, enabling the recovery of valuable soluble components from raw materials. With increasing energy costs and environmental concerns, industry specialists are looking for improved techniques requiring less solvents and energy consumption. Enhancing Extraction Processes in the Food Industry is a
Recently, the electrotechnologies based on the effects of pulsed electric fields (PEF), such as ohmic heating (OH) and DC electric field, have gained real interest in the field of food processing. These techniques efficiently enhance methods of extraction from food plants and dehydration of biosolids. The PEF and pulsed OH techniques preserve the nutritional, functional, structural and sensory properties of products better than conventional extraction technologies. The electrofiltration and electro-osmotic dewatering can be very effective for the separation of bioproducts and dehydration of food wastes. The first source book in the field, this book gives an overview the fundamental principle...
This book presents a comprehensive range of research on pulsed electric energy used in food processing, including sections on the fundamentals of electroporation and important techniques for the estimation of electroporation effects in various foods and biomass feedstocks. By focusing on application over theory, this book presents researchers with practical steps for processing techniques such as solid-liquid extraction, pressing, osmotic dehydration, drying, freezing and cooking. Special interest is given to the selective recovery and extraction of sugar, inulin, starch, proteins, polysaccharides, polyphenols, pigments, flavor compounds, phytochemicals and other of high-value components fro...
These proceedings comprise invited and contributed papers presented at PLMMP-2014, addressing modern problems in the fields of liquids, solutions and confined systems, critical phenomena, as well as colloidal and biological systems. The book focuses on state-of-the-art developments in contemporary physics of liquid matter. The papers presented here are organized into four parts: (i) structure of liquids in confined systems, (ii) phase transitions, supercritical liquids and glasses, (iii) colloids, and (iv) medical and biological aspects and cover the most recent developments in the broader field of liquid state including interdisciplinary problems.
One of the main concerns of the food industry is the need for high-quality fresh fruits and fruit products with good sensory quality, long shelf life, and high nutritional value. To meet these demands, new processing technologies are under investigation and development. Advances in Fruit Processing Technologies incorporates fundamentals in food processing as well as the advances made in recent years to improve final product quality. With contributions from a panel of international researchers who present a blend of classical and emerging technologies, the book explores: Ozone, ultrasound, irradiation, pulsed electric field, vacuum frying, and high-pressure processing Ultraviolet and membrane...
Natural products are used by the food, pharmaceutical and cosmetics industries, and extraction technologies and potential applications for plant extracts are of interest to many industrial sectors. Extraction of natural products in an economic and environmentally friendly way is of high importance to all industries involved. The second edition of this book presents an updated, holistic, in-depth view of the more environmentally benign techniques available for the extraction of natural products, along with their newest applications and case studies. Conventional and emerging extraction techniques are discussed in detail. New topics include enzymes, pulsed electric energy, and on-line/in-line analysis. Written for academics and industrialists working in both natural product extraction and green chemistry, this new edition provides a valuable update on current trends in the field.
Many novel technologies have been proposed in the attempt to improve existing food processing methods. Among emerging nonthermal technologies, high intensity pulsed electric fields (PEF) is appealing due to its short treatment times and reduced heating effects. This book presents information accumulated on PEF during the last 15 years by experienced microbiologists, biochemists, food technologists, and electrical and food engineers.
The final quality of a food product is impacted heavily by preservation technologies, such as chilling, freezing, and freeze-drying, as well as the numerous pretreatments that are routinely applied to foods. Adequate design and implementation of each of these treatments are critical to ensuring the integrity of the final food product, the productivity of the equipment, and reduced operation costs. Operations in Food Refrigeration explores the fundamental issues involved in heat and mass transfer in food refrigeration and examines aspects of other operations applied to chilled or frozen foods. Following an overview of basic concepts and general calculation procedures involved in cooling, free...
This is the second publication stemming from the International Congress on Engineering in Food, the first being Food Engineering Interfaces, based on the last ICEF10. The theme of ICEF 11, held in Athens, Greece in May 2011, is “Food Process Engineering in a Changing World.” The conference explored the ways food engineering contributes to the solutions of vital problems in a world of increasing population and complexity that is under the severe constraints of limited resources of raw materials, energy, and environment. The book, comprised of 32 chapters, features an interdisciplinary focus, including food materials science, engineering properties of foods, advances in food process technology, novel food processes, functional foods, food waste engineering, food process design and economics, modeling food safety and quality, and innovation management.
