Eurachem is a network of organisations in Europe having the objective of establishing a system for the international tra- ability of chemical measurements and the promotion of good quality practices. It provides a forum for the discussion of common problems and for developing an informed and considered approach to both technical and policy issues. It provides a focus for analytical chemistry and quality related issues in Europe. You can find more information about EURACHEM on the internet via "Eurachem -A Focus for Analytical Chemistry in Europe" (http: //www.eurachem.org). In particular the site Guides and Documents contains a number of different guides, which might help you to set up a quality system in your laboratory. The importance of quality assurance in analytical chemistry can best be described by the triangles depicted in Figs. 1 and 2. Quality is checked by testing and testing guaranties good quality. Both contribute to progress in QA (product control and quality) and thus to establishing a market share. Market success depends on quality, price, and flexibility. All three of them are interconnected. Before you can analyse anything the sample must be taken by someone. This must be of major concern to any analytical chemist. There is no accurate analysis wi- out proper sampling. For correct sampling you need a clear problem definition. There is no correct sampling without a clear problem definition

The enzymology of milk and other products is of enormous significance for the production and quality of almost every dairy product. Milk itself is a complex biological fluid that contains a wide range of enzymes with diverse activities, some of which have identifiable functions while others are present as an accidental consequence of the mechanism of milk secretion. Over time milk enzymology has become an incredibly essential component of milk and other dairy product production, and with advancing technology and processing techniques, its importance is at its peak. Dairy Enzymology presents an expansive overview of the enzymology of milk and other dairy products, focusing on the use of indigenous and endogenous enzymes in milk and exogenous enzymes in cheese processing. A full section is dedicated to the enzymology of bovine milk, focusing on the main families of indigenous enzymes as well as their potential significance in the mammary gland plus the technological significance for the properties of dairy products. Implications for the manufacture and ripening of cheese plus the use of enzymes such as alkaline phosphatase for measuring heat treatment in milk are explored in full, and the role of milk protease plasmin and other indigenous enzymes in the age-gelation is focused on. Further sections focus on enzymes found in raw milk and enzymes deliberately added for manufacture or modification of properties and the manufacture of food ingredients from dairy-derived ingredients. The key bacterial families are discussed in depth as well as their known contributions to the quality of dairy products. With its comprehensive scope and fully up-to-date coverage of dairy product enzymology, this text is a singular source for researchers looking to understand this essential dairy processing aspect.

This book focuses on food security and safety issues in Africa, a continent presently challenged with malnutrition and food insecurity. The continuous increase in the human population of Africa will lead to higher food demands, and climate change has already affected food production in most parts of Africa, resulting in drought, reduced crop yields, and loss of livestock and income. For Africa to be food-secure, safe and nutritious food has to be available, well-distributed, and sufficient to meet people's food requirements.

Additives have been used in the food sector for centuries, aiming to maintain or improve food quality in terms of freshness, appearance, texture and taste. Most food additives are synthetic chemical compounds classified as antioxidants, antimicrobials, colorants and sweeteners. In the last decades, several synthetic food additives have been correlated with adverse reactions in humans, which has caused the safety of synthetic food additives to be reviewed and discussed by international organizations. At the same time, there is increasing consumer demand for more natural and environmentally friendly food products and additives. Therefore, synthetic food additives have been replaced with natural food additives. Although the use of natural additives is a hot topic in food science, to date no book has systematically reviewed the application of natural additives in food products. Natural additives in foods presents an exhaustive analysis of the most recent advances in the application of natural additives in the food sector. Covering natural antioxidants, antimicrobials, colorants and sweeteners, this text also focuses on unconventional sources of natural additives, valorization and toxicological aspects, consumer attitudes and regulatory aspects. The main applications of natural antioxidants are fully covered, including polyphenols, ascorbic acid, carotenoids, tocopherols and proteins. Natural antimicrobial applications from polyphenols and essential oils to poly-L-Lysine are analyzed, as are natural colorants like anthocyanins, annatto, betalains and paprika.

Mycotoxins are the metabolites of fungus and are reported to contaminate nearly 25% of the food produced worldwide. The mycotoxins of most significance are the aflatoxins due to their severe health implications and their prevalence in food commodities on a larger scale. Aflatoxins are produced by certain species of fungi the most prominent among which are Aspergillus flavus, A. parasiticus and A. nominous. Food commodities of African and South Asian countries are especially reported to have aflatoxins well beyond the allowable limits but due to the global trade of food commodities developed countries are also prone towards the perils of aflatoxins. Moreover, climate changes may have a substantial impact on the distribution and global prevalence of aflatoxins in the near future. The International Agency for Research on Cancer (IARC) has classified the aflatoxins as group 1 category carcinogen. Aflatoxins are also reported as teratogenic, mutagenic, growth retardant, immunosuppressant and may also cause nervous system and reproductive system disorders. Preventive approaches involving good manufacturing from "farm to fork" are the major focus of the current food industry. The aim of our book is to provide readers with the most recent data and up-to-date studies from aflatoxins research, with specific focuses on (i) the impact of aflatoxins on human health, (ii) new approaches by the researchers from different parts of the world to degrade aflatoxins and (iii) potential preventive approaches that can significantly lessen the burden of aflatoxins in food products

Most bioactive compounds have antioxidant activity, particularly tocochromanols, phenolics (flavonoids and phenolic acids), methylxantines and capsaicinoids. Some of these compounds have also other properties important for human health. For example, vitamin E protects against oxidative stress, but it is also known for its "non-antioxidant" functions, including cell signalling and antiproliferation. Selenium compounds and indoleamins are the components of the antioxidant enzymes. Selenium makes vitamin E acquisition easier and controls its physiological functions. In taking part in enzymatic reactions and protecting the cell against free radicals, selenium shows immunomodulative, antiphlogistic, and antiviral activity. Capsaicinoids possess not only antioxidant, but also antibacterial, analgesic, weight-reducing and thermoregulation properties. Studies have also demonstrated their gastroprotective and anticancer properties. Analytical Methods in the Determination of Bioactive Compounds and Elements in Food explores both the influence of particular compounds on human health and the methods used for their determination. Chapters describe various aspects of food and plant analysis, including chromatographic and non-chromatographic approaches as well as hyphenated techniques. Readers of this book will gain a comprehensive understanding of the important groups of bioactive compounds relevant to human health.
