Description
Book SynopsisThe rapid and reliable detection of biological and chemical contaminants is extremely important in managing the safety of food and feed. "Rapid Methods" is a comprehensive reference resource for anyone interested in this subject. Developments in analytical techniques have led to the emergence of a wide range of rapid methods to complement the traditional methods. At the same time, the importance of method validation, proficiency testing, quality management, sampling and legislation have all become more widely recognised. "Rapid Methods" presents a firm base and structured framework for considering rapid analysis of biological and chemical contaminants in food and feed. The various chapters concentrate on the state of the art in rapid methods in regards to: legislation, sampling, method validation, microbial pathogens, biological materials like GMOs and allergens, toxins like bacterial food poisoning toxins, marine toxins and biogenic amines, chemicals like veterinary drugs, pesticides and dioxins. The editors firmly believe that the very nature of the theme, the excellence of the peer-reviewed papers and the holistic approach chosen in this book will draw an audience from both the food and feed industry as well as from the scientific community.
