Szefer P: Chemometrics in Food Control
Based on Elemental Analysis

Chemometrics in Food Control Based on Elemental Analysis

Essentials

In diesem Buch wird die Validierung analytischer Methoden beschrieben. Bei der Qualitätskontrolle von biologischen Arzneimitteln kommen häufig biologisch-analytische Methoden zum Einsatz, um wichtige Eigenschaften wie den Gehalt oder mögliche Verunreinigungen zu überprüfen. Die eingesetzten Methoden müssen vertrauenswürdige Ergebnisse liefern, damit bei der Bewertung der Ergebnisse keine falschen Schlüsse gezogen werden. Die Vertrauenswürdigkeit wird durch eine Validierung sichergestellt. Die Validierung von analytischen Methoden wird anhand einiger Beispiele dargestellt. Die geänderten Vorgaben ab Juni 2024 sind berücksichtigt.&nbsp;Der InhaltEinleitung.- Methodenkategorien.- Validierungsparameter.- Entwicklung von analytischen Methoden und Validierungsumgebung und -planung, Kontrollstrategie.- Validierung von biologisch analytischen Methoden.- Fehler, Probleme und Risiken bei der Methodendurchführung und Methodenvalidierung.- ZusammenfassungDer AutorPatric U. B. Vogel&nbsp;hat als Fachexperte eine Vielzahl von analytischen Methoden für die Qualitätskontrolle von pharmazeutischen Produkten entwickelt und validiert.&nbsp;Er ist im GMP/Pharma/Biotech-Bereich als Berater selbstständig und publiziert regelmäßig in den Bereichen GMP, analytische Methoden, Infektionskrankheiten und Statistik.&nbsp;

This textbook offers a comprehensive and practical guide to oenology, detailing the scientific principles and techniques essential for producing various types of wines. It provides in-depth discussions on the chemistry behind wines and winemaking processes.Starting with an introductory overview, the textbook examines the fundamental components of wine chemistry, such as alcohols, acids, and phenolic compounds. It then explores a range of winemaking methodologies, from traditional approaches to modern innovations, including detailed protocols for producing diverse wine types. Special attention is given to analytical methodologies crucial for assessing wine quality and authenticity, discussing parameters like sugars, acids, and phenolic content, as well as addressing potential adulterations. In the final sections, readers will gain insights into the role of oenological additives in shaping wine characteristics and their application in vinification processes. The last chapter covers the essentials of wine tasting, including setup, steps, sensory evaluation, types of tests, and the science behind flavors and aromas.Tailored for students, researchers, and oenology professionals, this textbook is also ideal for wine enthusiasts seeking to deepen their understanding of the scientific principles behind wine production and tasting.

Oenology in Practice

This book describes both the theory behind the analytical process and its practical application. The key methods of analytical chemistry are explained by providing the reader with just enough background and equations to understand what is being measured and how. Each chapter contains schematics to illustrate the defining features of the method described. The text itself is short and concise but provides plenty of references for further reading.

Macrocyclic oxoporphyrinogen molecules combine the ability to form strong supramolecular complexes with organic compounds and the ability to absorb light. These properties allow high-sensitivity colorimetric detection of acids in solution in the presence of oxoporphyrinogen. Moreover, protonated oxoporphyrinogens show various molecular dynamic processes on the millisecond timescale. This book offers deep analyses of colorimetric, binding and kinetic properties of oxoporphyrinogen-acid complexes. A detailed introduction is given for: theory of supramolecular binding and chemical kinetics; NMR spectroscopy with emphasis on multi-state chemical exchange including derivation of analytical spectral lineshapes; UV/vis spectroscopy and analysis of UV/vis spectra, using singular value decomposition (SVD). Implementation of the derived models in Mathematica is also provided. The experimental part addresses SVD analysis of UV/vis spectra illuminating the effect of protonation on various oxoporphyrinogen derivatives and explaining the colorimetric response. Furthermore, analysis of chemical exchange lineshapes offers insight into the dynamic processes present in protonated oxoporphyrinogens. The various models and techniques described in this book are widely applicable for other systems.

Plastic waste and single-use packaging are pressing global concerns—but food packaging is also crucial for reducing food waste, ensuring food safety and delivering essential information.&nbsp;Therefore, the packaging of food is also a sustainability solution, not just a problem. This book takes an interdisciplinary approach to the sustainability of food packaging, drawing from economics, environmental science, technology, social sciences and cultural studies. It explores the key principles of sustainable packaging while addressing critical gaps in current assessments as well as the role of innovation, policy and consumer behavior. With a holistic systems perspective, Sustainability Transition in Food Packaging:&nbsp;Systems, Actors and Innovation&nbsp;offers fresh insights into the challenges and innovations shaping the future of packaging. Essential reading for researchers, industry professionals and policymakers, this book provides actionable pathways toward a more sustainable and responsible food packaging system.

The sustainability of food packaging is a key priority in the food industry, as plastic waste and littering have become global concerns. Packaging waste accounts for over half of total global waste, predominantly from single-use plastic food packaging. Production of packaging consumes significant natural resources and contributes to climate change and pollution. However, packaging is also crucial for reducing food waste, protecting food safety, and providing vital information about contents, making it an essential sustainability solution, not just a problem.&nbsp;Sustainability Transition in Food Packaging: Systems, Actors, and Innovation&nbsp;explores sustainable food packaging from an interdisciplinary perspective, integrating economics, environmental science, technology, social sciences and cultural studies. This broad approach expands beyond the traditional focus on packaging as a product, considering its content and the services it provides. While sustainable packaging is often defined by four principles—effectiveness, efficiency, circularity, and safety—current applications primarily focus on the packaging itself, overlooking broader impacts such as marine and soil littering.&nbsp;Life cycle assessments (LCA) of packaging frequently ignore social, cultural, and economic sustainability aspects and often fail to account for the diverse interpretations of LCA standards. While the Product Environmental Footprint (PEF) offers a uniform solution, challenges remain due to undefined packaging category rules.Food packaging is rapidly evolving, driven by innovation, political action, and consumer demand. Given the global and varied nature of the food supply chain, one-size-fits-all solutions are insufficient. This book offers a holistic, interdisciplinary approach to sustainability, fostering dialogue and research across different research fields. It examines different conceptualizations of sustainable food packaging including methods for analyzing sustainability. The volume introduces novel methodologies, such as LCA with a focus on littering, and provides insights on overcoming the challenges of transitioning to a more sustainable food packaging system.
