Chemie in Lebensmitteln: Rückstände, Verunreinigungen, Inhalts- und Zusatzstoffe (Universitätstaschenbücher Ser. #675)
by Johannes Friedrich DiehlFast taglich berichten die Medien Ãber Lebensmittelskandale und "chemisch verseuchte" Nahrung. Ob Rackstände von Pflanzenschutzmitteln in Obst und Gemase, von Tierarzneimitteln in Fleisch, Milch und Eiern, ob Schwermetalle oder Dioxine - mit modernen Analysenverfahren kannen die geringsten Spuren solcher Stoffe sehr zuverlassig nachgewiesen werden. Aber welche gesundheitliche Risiken sind mit dem Vorhandensein dieser Substanzen in der Nahrung verbunden? Die Lebensmittelbranche versichert uns, ihre Produkte seien nicht nur unbedenklich zu genieà en, sondern gesundheitlich sicherer als je zuvor. Kritiker des heutigen Lebensmittelangebots warnen dagegen vor schlimmen Folgen. Was stimmt nun, welche Argumente kannen Ãberzeugen? Ein solch komplexes und heikles Thema wie "Chemie in Lebensmitteln" verlangt nach Beurteilung und Erlauterung durch unabhangige Experten. Als solcher hat sich Johannes Friedrich Diehl, viele Jahre Leiter der Bundesforschungsanstalt far Ernährung, durch zahlreiche Veraffentlichungen und Gutachten sowie durch seine Mitarbeit in Beratergremien einen Namen gemacht. Ohne zu beschanigen und ohne zu dramatisieren berichtet er Ãber die neuesten Erkenntnisse zur gesundheitlichen Qualitat von Lebensmitteln, Ãber aktuelle Entwicklungen bei der Zulassung und Verwendung von Zusatzstoffen, Ãber den erstaunlichen Wandel in den Ansichten Ãber Zusammenhänge zwischen Ernährung und Krebs, Allergien und anderen Krankheiten sowie Ãber die gesundheitsschädlichen und -fardernden Wirkungen natürlicher Lebensmittelinhaltsstoffe. Das mit fundiertem wissenschaftlichem Hintergrund, jedoch far einen breiten Leserkreis geschriebene Buch kann zugleich als fesselnde Lektare und als Nachschlagewerk Ernahrungsberatern, à rzten, Apothekern, Ökotrophologen, Agronomen und Chemikern dienen - natarlich auch allen, die sich eine eigene Meinung bilden wollen.

Chemistry Education and Sustainability in the Global Age
by Mei-Hung Chiu Jing-Wen Lin Hsin-Kai Wu Hsiao-Lin Tuan Chin-Cheng ChouThis edited volume of papers from the twenty first International Conference on Chemical Education attests to our rapidly changing understanding of the chemistry itself as well as to the potentially enormous material changes in how it might be taught in the future. Covering the full range of appropriate topics, the book features work exploring themes as various as e-learning and innovations in instruction, and micro-scale lab chemistry. In sum, the 29 articles published in these pages focus the reader's attention on ways to raise the quality of chemistry teaching and learning, promoting the public understanding of chemistry, deploying innovative technology in pedagogy practice and research, and the value of chemistry as a tool for highlighting sustainability issues in the global community. Thus the ambitious dual aim achieved in these pages is on the one hand to foster improvements in the leaching and communication of chemistry--whether to students or the public, and secondly to promote advances in our broader understanding of the subject that will have positive knock-on effects on the world's citizens and environment. In doing so, the book addresses (as did the conference) the neglect suffered in the chemistry classroom by issues connected to globalization, even as it outlines ways to bring the subject alive in the classroom through the use of innovative technologies.
Chemistry Lessons
by Meredith GoldsteinFrom advice columnist Meredith Goldstein, a dazzling, romantic, and emotionally resonant YA debut about a teen science whiz in Cambridge, Massachusetts, who tries to crack the chemical equation for lasting love and instead wreaks havoc on herself and the boys in her life. For seventeen-year-old Maya, the equation for happiness is simple: a dream internship at MIT + two new science nerd friends + a perfect boyfriend = one amazing summer. Then Whit dumps her out of the blue. Maya is miserable until she discovers that her scientist mother, before she died, was conducting research on manipulating pheromones to enhance human attraction. If Maya can finish her mother’s work, maybe she can get Whit back. But when her experiment creates chaos in her love life, she realizes that maybe love and loss can’t be understood using the scientific method. Can she learn to trust the unmeasurables of love and attraction instead?

Chemistry and Chemists in Florence: From the Last of the Medici Family to the European Magnetic Resonance Center (SpringerBriefs in Molecular Science)
by Marco Fontani Mary Virginia Orna Mariagrazia CostaThis brief offers a novel vision of the city of Florence, tracing the development of chemistry via the biographies of its most illustrious chemists. It documents not only important scientific research that came from the hands of Galileo Galilei and the physicists who followed in his footsteps, but also the growth of new disciplines such as chemistry, pharmaceutical chemistry, and biochemistry. It recounts how, in the Middle Ages, chemistry began as an applied science that served to bolster the Florentine economy, particularly in the textile dyeing industry. Later, important scientific collections founded by the ruling Medici family served as the basis of renowned museums that now house priceless artifacts and instruments. Also described in this text are the chemists such as Hugo Schiff, Angelo Angeli, and Luigi Rolla, who were active over the course of the following century and a quarter. The authors tell the story of the evolution of the Royal University of Florence, which ultimately became the University of Florence. Of interest to historians and chemists, this tale is told through the lives and work of the principal actors in the university's department of chemistry.
Chemistry and Food Safety in the EU: The Rapid Alert System for Food and Feed (RASFF) (SpringerBriefs in Molecular Science)
by Salvatore Parisi Caterina Barone Ramesh Kumar SharmaThis Brief provides a general description of the European Rapid Alert System for Food and Feed (RASFF). It describes the RASFF approach on the legal level and with reference to notification procedures, including also new tools, which were launched in 2014: iRASFF and the RASFF Consumer Portal. In an introduction, the present status of the RASFF, which had originally been introduced in 1979, is briefly reviewed. It is described as the main basis of modern food policy in Europe, enabling member countries to take rapid corrective actions on the one hand, and to perform statistically reliable analyses of food-related hazards on the other hand. One chapter contains a statistical evaluation of RASFF notifications in general, and specifically with regard to chemical contaminants, including also allergens. In another chapter, reasons for rejections of food and feed at the European borders are analyzed in selected case studies. The Brief provides an easy description for the chemical dangers and contaminants it is referring to, outlining the names, properties, uses and importance in the food and feed industry, toxicological effects, and contamination sources. The last chapter offers an outlook on the future of the RASFF and possible expectations.

Through four chapters, the authors describe the chemistry of food additives, the regulatory classification of additives on a large-scale, the risks involved in using chemicals for food preparation - including implications this has on food hygiene, and case-study examples taken from the dairy industry. More specifically, chapter one provides a list of the technological purposes of food additives defined for European use; chapter two explains the 'General Standards for Food Additives' (Codex Alimentarius Commission) which is a harmonised, workable and indisputable international standard; chapter three describes the use of selected food additives in the dairy sector, particularly with relation to the production of yoghurt products; and chapter four addresses the impact of additives on human health. This brief is of interest to researchers working in the area of food production and international regulation, both in academia and industry.
Chemistry and Hygiene of Food Gases (SpringerBriefs in Molecular Science)
by Salvatore Parisi Pasqualina Laganà Paolo Patanè Santi Delia Maria Anna Coniglio Giovanni Campanella Maria Assunta Cava Maria Elsa GambuzzaThis book focuses on the use of food gases in the food industry, their different applications and their role in food processing, packaging and transportation. Since these gases come into contact with food, they must comply with strict of labeling, purity and hygiene standards in order to ensure food safety.The book discusses various implications of food gases in the food chain, providing examples of how they can be used to limit food waste and losses. The first two chapters examine the classification and role of food gases in Europe, and the third chapter then explores the chemical and physical features of commonly used food gases in the food and food packing industries. The fourth chapter highlights the impact of food gases on human health due to their possible abuse and misuse. This book appeals to researchers and professionals working in food production and quality control.
Chemistry and Safety of South American Yerba Mate Teas (SpringerBriefs in Molecular Science)
by Candela IommiThis book explores the traditional use of Ilex paraguariensis, a plant that is widely distributed in South America. Thanks to its purported properties, it has been used for centuries in the form of teas with a variety of names, including: ‘yerba mate’ (Argentina), ‘chimarrão’ (Brazil), and others. Ilex paraguariensis and its teas (also referred to as ‘mate teas’) are well known because of their alleged pharmacological effects in numerous common conditions, including obesity, osteoporosis, constipation, arthritis, and hypertension. These effects are generally ascribed to yerba mate teas because the botanical species contains bioactive and stimulating substances like caffeine (originally dubbed ‘mateine’), various alkaloids, and several phenolic acids. Interestingly, the chemical profiles of these teas can fluctuate over time, creating serious production problems. As a result, it is difficult to reliably determine their safety and health effects on humans. In response to the global interest in these products, this book offers a reference guide to ‘yerba mate’/‘chimarrão’ teas. It analyzes their chemical profiles, discusses their bioactive features, and addresses their safety and health effects. In addition, since the cultural heritage of yerba mate has greatly contributed to its international success, the book also provides information on its historical legacy, regulatory aspects, and the global market.
Chemistry and Technology of Emulsion Polymerisation
by A. M. van HerkChemistry and Technology of Emulsion Polymerisation 2e provides a practical and intuitive explanation of emulsion polymerization, in combination with both conventional and controlled radical polymerization. For those working in industry, coupling theory with everyday practice can be difficult. By carefully explaining the principles of the reaction, based on well-designed experimental investigation, the book explains how the principles relate to practical application.The second edition of this book includes a new chapter on morphology of latex particles, a rapidly progressing area where modelling the thermodynamic and kinetic aspects of phase separation and morphology has developed into a mature and powerful tool to predict and control morphology of latex particles. Another area that is rapidly progressing is the application of controlled radical polymerisation in emulsion polymerization. Controlled radical polymerisation is used in aiding encapsulation of inorganic particles like pigment particles and clay platelets. These latest developments are included in the second edition.
Chemistry and Technology of Honey Production (SpringerBriefs in Molecular Science)
by Ettore BaglioThis Brief explains and discusses honey and its production from a chemical perspective. It outlines why honey is a special and unique food, being produced by bees from the nectar of plants or from secretions of living parts of plants. Although glucose and fructose are the main constituents of honey, its overall composition is far from being simple or uniform: other substances such as organic acids, enzymes, or minerals are found in varying amounts. In this Brief, the author addresses the factors that influence the composition of the honey as well as the consequences that the composition has on properties such as color, crystallization, density, viscosity, or the refractive index. This Brief also introduces some of the most commonly used quality parameters for the determination of ageing and/or overheating: 5-hydroxymethylfurfural (HMF) and diastase. Other recently proposed constituents for quality parameters are also mentioned, e. g. 1,2 dicarbonyl compounds (3 deoxyglucosone, methylglyoxal, glyoxal) and furosine, also named 2-furoylmethyl lysine.

Chemistry as a Game of Molecular Construction
by Roald Hoffmann Sason Shaik Racheli Ben-Knaz Wakshlak Dina A. Sharon Usharani DandamudiThe proposed textbook takes the students into a fascinating journey that shows the universal aspect of chemistry: Chemistry is the window given to mankind to glimpse into his material-chemical essence and come to terms with its limitations. In the introductory chapter/lecture, the textbook discusses the connection between the "chemical matter" and love, sex, depression, addiction--all the properties we call "human". As we are made of chemical matter, this chapter makes a point why knowledge of chemistry is so essential to mankind. This preamble is followed by about 14 short chapters/lectures, which introduce chemistry as molecule building process, like a game of Lego.
