Available in PDF, EPUB and Kindle. Book excerpt: "When oil is dispersed in the form of droplets in water in the presence of a suitable surfactant, oil-in-water (O/W) emulsions are formed. They have unique chemical properties covering a wide range of applications from environmental technologies to foodstuffs. In this book, authors discuss the preparation of O/W emulsions and their implications in environmental and food problems, covering hot topics including the composition and spill behavior of diluted bitumens, the use of O/W emulsions as platforms for the synthesis of waterborne particles, new methods to separate oil from water in oily wastewater, emerging technologies for the preparation of O/W emulsions, control of the oxidative status of lipids in oil by employing antioxidants to minimize lipid oxidation, parameters affecting O/W microbial stability and environmental issues and evaluation of interfacial barriers created by emulsifiers"--

Download or read book Crystallization in Foods written by Richard W. Hartel and published by Boom Koninklijke Uitgevers. This book was released on 2001-03-31 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the food industry, controlling crystallization is a key factor in quality as it relates to texture, with some foods requiring the promotion of crystallization and others its prevention. In the first publication to focus specifically on this process as it applies to food, Crystallization in Foods covers fundamental principles in ice, sugar, and lipid crystallization, and their applications. Drawing on examples throughout of the practical use and impact of crystallization on food structure, texture, and quality; and enhanced with numerous equations and illustrations, Crystallization in Foods is a valuable resource for food engineers and other scientists working with crystallization in foods, particularly in the dairy, confectionery, frozen foods, and baked goods industries. In addition, this book may be of interest to scientists and other professionals in the personal care and cosmetics industry, which shares some of the same quality and texture concerns as the food industry.

Download or read book Food Emulsifiers and Their Applications written by Richard W Hartel and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food emulsions have existed since long before people began to process foods for distribution and consumption. Milk, for example, is a natural emulsion/colloid in which a nutritional fat is stabilized by a milk-fat-globule membrane. Early processed foods were developed when people began to explore the art of cuisine. Butter and gravies were early foods used to enhance flavors and aid in cooking. By contrast, food emulsifiers have only recently been recognized for their abil ity to stabilize foods during processing and distribution. As economies of scale emerged, pressures for higher quality and extension of shelf life prodded the de velopment of food emulsifiers and their adjunct technologies. Natural emulsifiers, such as egg and milk proteins and phospholipids, were the first to be generally utilized. Development of technologies for processing oils, such as refining, bleaching, and hydrogenation, led to the design of synthetic food emulsifiers. Formulation of food emulsions has, until recently, been practiced more as an art than a science. The complexity offood systems has been the barrier to funda mental understanding. Scientists have long studied emulsions using pure water, hydrocarbon, and surfactant, but food systems, by contrast, are typically a com plex mixture of carbohydrate, lipid, protein, salts, and acid. Other surface-active ingredients, such as proteins and phospholipids, can demonstrate either syner- XV xvi Preface gistic or deleterious functionality during processing or in the finished food.

Available in PDF, EPUB and Kindle. Book excerpt: Emulsions occur either as end products or during the processing of products in a huge range of areas including the food, agrochemical, pharmaceutical, paint and oil industries. Despite over one hundred years of research in the subject, however, a quantitative understanding of emulsions has been lacking. Modern Aspects of Emulsion Science presents a comprehensive description of both the scientific principles in the field and the very latest advances in research in this important area of surface and colloid science. Topics covered include emulsion formation, type, stability (creaming, flocculation, ripening, coalescence), monodisperse and gel emulsions, and applications. Emphasis has been placed on relating the chemistry of the surfactant or protein adsorbed at the oil-water interface to the principles of the physics involved in the bulk emulsion property. The book has been written by a collection of the world's leading experts in the field, and covers both experimental and theoretical approaches. Modern Aspects of Emulsion Science fills a real gap in the market, being the only book of its kind in print. As such it will prove essential reading for graduates and researchers in this subject, in both academia and industry.

Available in PDF, EPUB and Kindle. Book excerpt: Omega-3 Delivery Systems: Production, Physical Characterization and Oxidative Stability offers the most recent updates for developing, characterizing, and stabilizing both traditional and novel omega-3 delivery systems, including their final incorporation into food matrices and physicochemical changes during digestion. The book brings chapters on novel omega-3 delivery systems (e.g., high-fat emulsions, Pickering emulsions, electrosprayed capsules, and solid lipid nanoparticles), the application of advanced techniques to evaluate physical and oxidative stabilities (e.g., SAXS, SANS, ESR, and super-resolution fluorescence microscopy), and new developments of food enrichment and physicochemical changes during digestion. The book provides a unique multidisciplinary and multisectoral approach, i.e., featuring authors from industry and academy. Long chain omega-3 polyunsaturated fatty acids (PUFA) present numerous health benefits; however, the consumption of natural products rich in omega-3 PUFA (e.g., fish, krill, and algae) is not enough to reach the daily-recommended values. Therefore, the food industry is highly interested in producing omega-3 fortified foods. Brings a holistic approach of omega-3 delivery systems, bringing scientific understanding on production, physical characterization, and oxidative stability Covers key aspects to develop, characterize, and use omega-3 delivery systems for food enrichment, considering physicochemical changes occurring during digestion Serves as an interface between lipid oxidation and colloids chemistry, encapsulation techniques, soft matter physics, food development, and nutrients bioavailability
