Available in PDF, EPUB and Kindle. Book excerpt: This book describes industrial applications of polyolefins from the researchers' perspective. Polyolefins constitute today arguably the most important class of polymers and polymeric materials for widespread industrial applications. This book summarizes the present state of the art. Starting from fundamental aspects, such as the polymerization techniques to synthesize polyolefins, the book introduces the topic. Basic knowledge about polyolefin composites and blends is explained, before applications aspects in different industry sectors are discussed. The spectrum comprises a wide range of applications and industry sectors, such as the packaging and food industry, the textile industry, automotive and buildings, and even biomedical applications. Topics, which are addressed in the various chapters, comprise synthesis and processing of the materials; their classification; mechanical, physical and technical requirements and properties; their characterization; and many more. In the end of the book, even the disposal, degradation and recycling of polyolefins are addressed, and light is shed on their commercial significance and economic value. In this way, the book follows the entire 'lifetime' of polyolefin compounds and materials: from their synthesis and processing, over applications, to the recycling and reuse of disposed or degraded polyolefin substrates.

Download or read book Principles and Applications of Gas Chromatography in Food Analysis written by Michael H. Gordon and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: The food analyst plays an important role in modern society. Stricter control over additives in food and concern about the effects of contamination of food by industrial and agricultural chemicals are among the developments which are leading to an increasing emphasis on detailed and accurate analysis of food. However. analysis of food is required for many reasons, including detection of toxic components, monitoring legislation, detecting adulteration, formulation of controlled diets, controlling formulation during product development and detecting changes in food during storage and processing. Foods comprise a complex mixture of components and food analysis requires efficient methods of separation with high sensitivity or specificity of detection. Although many food components are involatile or thermally labile and therefore not suitable for analysis by gas chromatography, other components are volatile and this technique is the preferred analytical method. Developments in methods of derivati zation, injector design and column technology have also extended the applicability of gas chromatography to the analysis of relatively involatile compounds.

Download or read book Headspace Analysis of Foods and Flavors written by American Chemical Society. Meeting and published by Springer Science & Business Media. This book was released on 2001-08-31 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Headspace gas analysis is an analytical technique that has been successfully applied to food flavors for over 20 years but has experienced a resurgence of interest and innovation in recent years. In its truest form, headspace analysis represents the direct collection and analysis of the mixture of vapors in the space immediately above a food or beverage. The technique offers several advantages for workers interested in how a product smells and ultimately tastes. It offers the advantages of speed, simplicity, and, more importantly, represents the aroma profile a consumer is likely to experience just before consuming the product. Since only volatile components are collected, the sample is totally free of nonvolatile residues which commonly plague comparison liquid-liquid extracts of the same product. This is the first book devoted to headspace analysis in foods and beverages in more than 20 years. The publication contains chapters on the basic theory of headspace analysis, as well as the theory and application of newly developed headspace techniques, such as solid phase micro extraction, SPME and electronic noses. New concentrating and desorption techniques are described in addition to a raft of food applications including tomato and citrus juices, alcoholic beverages, baguettes, dairy products, lipids, grill flavoring, baked potato, and meat. Chapters on off-flavors as well as aroma-food matrix interactions are also included. "This is the bible of headspace analysis. If you are involved in, or planning on becoming involved, or want to learn more about, this incredible subject , then buy this book immediately!" – Aubrey Parsons, governing council member, International Union for Food Science and Technology
