Book excerpt: Advanced Component Identification in Complex Mixtures Essential oils are mixtures consisting of monoterpene andsesquiterpene hydrocarbons, their oxygenated derivatives, andaliphatic oxygenated compounds. The difficulties that arise in theGC-MS peak identification of these complex samples is due to thefact that many terpenes have identical mass spectra. This is aconsequence of similarities both in the initial molecule, or in thefragmentation patterns and rearrangements after ionization. Hence,MS identification of these compounds should always be accompaniedby retention time information that may support the MS librarysearch results. This innovative MS library for natural and synthetic products(essential oils, perfumes, etc.) makes the identification ofunknown compounds in complex mixtures easier, faster and morereliable. The use of chromatographic information, such as LinearRetention Index (LRI), can be used to filter MS results, enablingthe more reliable peak assignment of components in complexmixtures. Mass spectra, relative to standard and well-known simple matrixcomponents, were obtained and recorded through GC-MSseparation/identification. Furthermore, traditional informationrelative to each component (CAS number, common name, CAS name,molecular weight, compound formula, chemical class) plus linearretention index values are entered. Flavors and Fragrances of Natural and Synthetic Compounds,3rd edition contains >3000 mass spectra, LRI retentiondata, calculated Kovats RI, and searchable chemical structures ofcompounds of interest for the flavors and fragrances industry.Prepared by the Prof. Luigi Mondello under rigorous measurementconditions, the mass spectral library contains compounds central toflavor and fragrance research.

Available in PDF, EPUB and Kindle. Book excerpt: The volumes of this classic series, now referred to simply as "Zechmeister" after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the series' inauguration in 1938. It is therefore not really surprising to find out that the list of contributing authors, who were awarded a Nobel Prize, is quite long: Kurt Alder, Derek H.R. Barton, George Wells Beadle, Dorothy Crowfoot-Hodgkin, Otto Diels, Hans von Euler-Chelpin, Paul Karrer, Luis Federico Leloir, Linus Pauling, Vladimir Prelog, with Walter Norman Haworth and Adolf F.J. Butenandt serving as members of the editorial board. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline.

This book was released on 2011-05-17 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Gas Chromatography and Mass Spectrometry: A Practical Guide follows the highly successful first edition by F.G. Kitson, B.S. Larsen, and C.N. McEwen (1996), which was designed as an indispensible resource for GC/MS practitioners regardless of whether they are a novice or well experienced. The Fundamentals section has been extensively reworked from the original edition to give more depth of an understanding of the techniques and science involved with GC/MS. Even with this expansion, the original brevity and simple didactic style has been retained. Information on chromatographic peak deconvolution has been added along with a more in-depth understanding of the use of mass spectral databases in the identification of unknowns. Since the last edition, a number of advances in GC inlet systems and sample introduction techniques have occurred, and they are included in the new edition. Other updates include a discussion on fast GC and options for combining GC detectors with mass spectrometry. The section regarding GC Conditions, Derivatization, and Mass Spectral Interpretation of Specific Compound Types has the same number of compound types as the original edition, but the information in each section has been expanded to not only explain some of the spectra but to also explain why certain fragmentations take place. The number of Appendices has been increased from 12 to 17. The Appendix on Atomic Masses and Isotope Abundances has been expanded to provide tools to aid in determination of elemental composition from isotope peak intensity ratios. An appendix with examples on "Steps to follow in the determination of elemental compositions based on isotope peak intensities" has been added. Appendices on whether to use GC/MS or LC/MS, third-party software for use in data analysis, list of information required in reporting GC/MS data, X+1 and X+2 peak relative intensities based on the number of atoms of carbon in an ion, and list of available EI mass spectral databases have been added. Others such as the ones on derivatization, isotope peak patterns for ions with Cl and/or Br, terms used in GC and in mass spectrometry, and tips on setting up, maintaining and troubleshooting a GC/MS system have all been expanded and updated. Covers the practical instruction necessary for successful operation of GC/MS equipment Reviews the latest advances in instrumentation, ionization methods, and quantitation Includes troubleshooting techniques and a variety of additional information useful for the GC/MS practitioner A true benchtop reference A guide to a basic understanding of the components of a Gas Chromatograph-Mass Spectrometer (GC-MS) Quick References to data interpretation Ready source for information on new analyses

Available in PDF, EPUB and Kindle. Book excerpt: During the last few years, industrial fermentation technologies have advanced in order to improve the quality of the final product. Some examples of those modern technologies are the biotechnology developments of microbial materials, such as Saccharomyces and non-Saccharomyces yeasts or lactic bacteria from different genera. Other technologies are related to the use of additives and adjuvants, such as nutrients, enzymes, fining agents, or preservatives and their management, which directly influence the quality and reduce the risks in final fermentation products. Other technologies are based on the management of thermal treatments, filtrations, pressure applications, ultrasounds, UV, and so on, which have also led to improvements in fermentation quality in recent years. The aim of the issue is to study new technologies able to improve the quality parameters of fermentation products, such as aroma, color, turbidity, acidity, or any other parameters related to improving sensory perception by the consumers. Food safety parameters are also included.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in instrumentation and applied instrumental analysis methods have allowed scientists concerned with food and beverage quality, labeling, compliance, and safety to meet ever increasing analytical demands. Texts dealing with instrumental analysis alone are usually organized by the techniques without regard to applications. The biannual review issue of Analytical Chemistry under the topic of Food Analysis is organized by the analyte such as N and protein, carbohydrate, inorganics, enzymes, flavor and odor, color, lipids, and vitamins. Under 'flavor and odor' the subdivisions are not along the lines of the analyte but the matrix (e.g. wine, meat, dairy, fruit) in which the analyte is being determined. In "Instrumentation in Food and Beverage Analysis" the reader is referred to a list of 72 entries entitled "Instrumentation and Instrumental Techniques" among which molecular spectroscopy, chromatographic and other sophisticated separations in addition to hyphenated techniques such as GS-Mass spectrometry. A few of the entries appear under a chapter named for the technique. Most of the analytical techniques used for determination, separations and sample work prior to determination are treated in the context of an analytical method for a specific analyte in a particular food or beverage matrix with which the author has a professional familiarity, dedication, and authority. Since, in food analysis in particular, it is usually the food matrix that presents the research analytical chemist involved with method development the greatest challenge.

Available in PDF, EPUB and Kindle. Book excerpt: It happened in Manchester, May 12-14, 2004. - For the fifth time since the early 1990's the Royal Society of Chemistry and the Society of the Chemical Industry jointly held their 'flavours & fragrances' conference, this time in the Manchester Conference Centre of the UMIST Manchester. The meeting saw over one hundred participants from one dozen countries, and was the largest of the series so far. In two and a half days divided into five sessions, twenty-five speakers from academia and industry alike presented their recent research results related to this exciting field, including Natural Products, Foods and Flavors, Perfumery and Olfaction, and last but not least Fragrance Chemistry. Research is more than ever central to the F&F industry with its constant demand for innovation and its frequently changing trends. Especially, in the classic and well-explored domains of musks and amber odorants fascinating new discoveries were made only very recently, which proves the endless possibilities in the search for new aroma chemicals. This was also reflected in the logo of the conference, which featured Ambrocenide? as a new powerful ambery odorant that emerged from classical cedrene chemistry - and it is as well reflected in four of the sixteen conference papers that are collected in this special issue of Chemistry & Biodiversity. With its focus on biorelevant chemicals, Chemistry & Biodiversity was predestined to publish the diverse highlight papers of the 'flavours & fragrances' conference. Fragrance and fragrance materials by definition elicit a biological response, serve as versatile signals, trigger the sense of smell and taste in various ways - and every odorant design is nothing more than 'chemistry probing nature'. But Fragrance Chemistry can also document and even preserve the biodiversity of scents, as was the topic of the lecture of Roman Kaiser, which had been published in advance as the first full paper of Chemistry & Biodiversity.
