The quality and safety of food are crucial for human nutrition. However, evaluating the chemical composition of food is challenging for the analyst and requires powerful methods. Chromatography and mass spectrometry (MS) is the gold standard for analyzing complex food samples, including raw materials and intermediate and finished products. Mass Spectrometry in Food Analysis covers the MS-based analysis of different aspects of food quality, which include nutritional value, profile of macronutrients (proteins, lipids, and carbohydrates), micronutrients (vitamins), and nutraceutical active compounds. Additionally, sensory quality, flavor, food pigments, safety, and detection of pesticides, contact materials, veterinary drugs and pharmaceuticals, organic pollutants, and pathogens are covered. Key Features: Contains the basics of mass spectrometry and experimental strategies Explores determination of macro- and micronutrients Analyzes sensory and nutraceutical food quality Discusses detection of contaminants and proof of authenticity Presents emerging methods for food analysis This book contains an introductory section that explains the basics of MS and the difference between targeted and untargeted strategies for beginners. Further, it points out new analytical challenges, such as monitoring contaminants of emerging concern, and presents innovative techniques (e.g., ambient ionization MS and data mining).

Metabolomics and proteomics allow deep insights into the chemistry and physiology of biological systems. This book expounds open-source programs, platforms and programming tools for analysing metabolomics and proteomics mass spectrometry data. In contrast to commercial software, open-source software is created by the academic community, which facilitates the direct interaction between users and developers and accelerates the implementation of new concepts and ideas. The first section of the book covers the basics of mass spectrometry, experimental strategies, data operations, the open-source philosophy, metabolomics, proteomics and statistics/ data mining. In the second section, active programmers and users describe available software packages. Included tutorials, datasets and code examples can be used for training and for building custom workflows. Finally, every reader is invited to participate in the open science movement.

On the BC Robert Winkler was born in Budapest and graduated from high school. He was drafted into forced labor in 1944. After the war he entered the technical university of Budapest and graduated in structural engineering. He immigrated to the US in 1957 after the Hungarian Revolution and had a productive career in civil engineering. He has been married to Jolan Winkler for 37 years and lives in Riverdale, New York. This book tells the story of a young Hungarian Jewish man drafted into forced labor and his numerous escape attempts. The "escape artist" vividly describes the tricks he used to fool the Hungarian and the Germans who inadvertently shielded him from Hungarian captors.

Nitrogruppen finden sich in verschiedenen Naturstoffen mit biologischer Aktivitat. Deren Biosynthese kann auf unterschiedlichen Routen stattfinden, wobei die Oxidation von Aminogruppen die wichtigste darstellt. Im Biosynthese-Gencluster fur Aureothin, einer Verbindung mit zytotoxischer, insektizider und antifungaler Aktivitat aus dem Aktinomyzeten Streptomyces thioluteus, wurde eine neuartige N-Oxygenase, AurF, entdeckt. Die funktionelle und strukturelle Charakterisierung dieses Enzyms fuhrte zu neuen Erkentnissen uber die biologische Nitrogruppenbildung. Es wurde gezeigt, dass die N-Oxygenierung von Aminogruppen schrittweise uber Hydroxylamin- und Nitrosointermediate ablauft. Die rekombinante Produktion von AurF ermoglichte eine sorgfaltige biochemische Charakterisierung. Rontgenkristallstrukturen ergaben dabei einen neuartigen binuklearen Mangan-Cluster im aktiven Zentrum des Enzyms. Zudem wird gezeigt, wie die streng regio- und chemoselektive Reaktion fur die Biokatalyse genutzt werden kann."
