This book was released on 2012-03-05 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will review old and new methods to study emulsion stability and structure. Examples of emulsion-based foods include ice cream, yoghurt, and mayonnaise. The physicochemical properties of emulsions play an important role in food systems, as they directly contribute to the texture, sensory and nutritional properties of foods. One of the main properties is stability, which refers to the ability of an emulsion to resist physical changes over time. The development of an effective strategy to prevent undesirable changes in the properties of a particular food emulsion depends on the dominant physicochemical mechanism(s) responsible for the changes. In practice, two or more of these mechanisms may operate in concert. It is therefore important for food scientists to identify the relative importance of each mechanism, the relationship between them, and the factors that influence them, so that effective means of controlling the stability and physicochemical properties of emulsions can be established. Several techniques are used to study the physical behavior and structure of emulsions. Each technique has its advantages and disadvantages and provides different insights into the destabilization mechanisms. Among the oldest methods used to study emulsion stability is visual observation and small deformation rheometry. More recently, other techniques, such as ultrasound profiling, microscopy, droplet size distribution, and measurement of surface concentration to characterize adsorbed protein at the interface, have also been employed. Some of these techniques, such as droplet size distribution, involve some form of dilution. However, dilution disrupts some structures that play an important role in stability. The ability to study the stability of food emulsions in their undiluted form may reveal subtle nuances about their stability. Diffusing wave spectroscopy (DWS), laser scanning confocal microscopy (LSCM), nuclear magnetic resonance (NMR), and Turbiscan are among the more powerful, non-perturbing techniques used to characterized emulsions.

Available in PDF, EPUB and Kindle. Book excerpt: Nutrient Delivery: Nanotechnology in the Agri-Food Industry, Volume Five, discusses the fabrication, merits, demerits, applications, and bioavailability enhancement mechanisms of various nanodelivery systems. Recent developments in various nanodelivery systems are also highlighted. Volume 5 contains twenty chapters, prepared by outstanding international researchers from Argentina, Brazil, Canada, China, Croatia, India, Iran, Ireland, México, Pakistan, Portugal, Serbia, Sri Lanka, and the United States. In recent years, the delivery of micronutrients at nanoscale has been widely studied as these systems have the potential to improve bioavailability, enable controlled release and enhance stability of food bioactives to a greater extent. The nanodelivery systems typically consist of the food bioactive compound encapsulated and stabilized in food grade ingredients such as lipids, proteins or polysaccharides with diameters ranging from 10 nm to 1000 nm. Among these, the lipid based delivery systems such as nanoemulsions, solid lipid nanoparticles, nanoliposomes and micelles are widely studied for the delivery of lipophilic bioactive compounds. These delivery vehicles improve the solubility, permeability, stability and bioavailability of the lipophilic compounds thereby enhancing their potential for oral delivery and functional food development. On the other hand, the hydrophilic bioactives are delivered through protein, polysaccharide or biopolymer based colloidal nanosystems such as hydrogels, nanogels and polymer nanoparticles. The major concern other than solubility is the intestinal permeability of the micronutrients. For instance, the delivery system for compounds with poor intestinal permeability and low solubility need to be carefully designed using suitable lipids and surfactants. Offers updated material for undergraduate and postgraduate students in food science, biotechnology, and related engineering fields Provides a valuable resource of recent scientific progress, along with most known applications of nanomaterials in the food industry for researchers, engineers, and academics Includes novel opportunities and ideas for developing or improving technologies in the food industry

Download or read book Intravenous Lipid Emulsions written by P.C. Calder and published by Karger Medical and Scientific Publishers. This book was released on 2014-11-26 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lipids have been in clinical use as components of intravenous nutrition for over 50 years. Over the last 15 years, new and improved lipids that include olive oil and/or fish oil have replaced the more traditional ones. These new lipids offer the opportunity to deliver high amounts of fatty acids and possess different functional properties: in particular, they can influence inflammatory processes, immune responses and hepatic metabolism. This book brings together articles written by leading international authorities in the area of intravenous lipids. Contributions discuss the latest findings in the field, ranging from pre-clinical research to the most recent clinical trials. Lipid functionality and utility in pediatric, adult surgical and critically ill patients are covered, as is the use of lipids in long-term home parenteral nutrition. Addressing a broad spectrum of topics, this publication provides a wealth of information for basic scientists, clinical researchers and clinical practitioners alike.

Book excerpt: The fifth volume in the Advances in lipid methodology series is the first with new editor, Richard O. Adlof, but its objectives are still those of the previous editor, William W. Christie: 'To provide readable, up-to-date reviews of rapidly expanding areas of lipid analysis and practical examples which should be of immediate use to lipid analysts'. As in the previous volumes of Advances in lipid methodology, the editor has chosen leading international experts to write individual chapters. Volume 5 contains four chapters on specific methodologies of lipid analysis and three which describe specific applications or standardization of methods. The methodologies are different scanning calorimetry for the study of physical properties of fats and oils; silver ion chromatography; atmospheric-pressure chemical-ionization mass spectrometry (APCI-MS); and supercritical fluid chromatography (SFC). Chapters on specific applications cover the analysis of genetically modified oils and the use of fatty acid profiling in the characterization of metabolic diseases. A further chapter provides an overview of the official standard methods used for fats and oils analysis and gives extensive listings of information on standards organizations.
