New developments in mass spectrometry have allowed routine identification and lowered limits of detection at levels only imagined a decade ago. Thousands of contaminants and residues in the food supply and the environment are now being reported. Between 2005 and 2010, more than 5,000 publications covering TOF-MS and environmental and food analysis were published, showing the importance of the technique in these applications. This book covers the basic principles of method development in GC- and LC-TOF-MS as well as the main operational parameters related to TOF-MS. The second part focuses on the relevant environmental applications, including quality control aspects as well as data collection. The third part is devoted to relevant applications in food analysis, including validation procedures for screening analysis as well as relevant databases. Outlines basic concepts and principles of gas and liquid chromatography TOF-MS and its application in food analysis Includes quality control and data collection techniques Focuses on environmental implications and safety concerns

Long used in sacred ceremonies and associated with good health, the nutritional and health promoting benefits of olives and olive oils have been proven by an ever-increasing body of science. From cardiovascular benefits to anti-microbial, anti-cancer, antioxidant activity and effects on macrophages and aptoptosis to cellular and pathophysiollogical process, olives and olive oils are proving important in many healthful ways. For example, reactive components in olive oils or olive oil by-products have now been isolated and identified. These include tyrosol, hydroxytyrosol, 3,4-dihydroxyphenyl acetic acid elenolic acid and oleuropein. Oleic acid is the main monosaturated fatty acid of olive oil. These have putative protective effects and modulate the biochemistry of a variety of cell types including those of the vascular system. Some but not all components have been characterised by their putative pharmacological properties. It is possible that usage of these aforementioned products may have beneficial application in other disease. However, in order for this cross-fertilization to take place, a comprehensive understanding of olives and olive oils is required. Finding this knowledge in a single volume provides a key resource for scientists in a variety of food an nutritional roles. Key Features: * Explores olives and olive oil from their general aspects to the detailed level of important micro-and micronutrients * Includes coverage of various methodologies for analysis to help scientists and chemists determine the most appropriate option for their own studies, including those of olive-related compounds in other foods * Relates, in a single volume resource, information for food and nutritional chemists, pharmaceutical scientists, nutritionists and dieticians * Presents information in three key categories: General aspects of olives an olive oils; Nutritional, pharmacological and metabolic properties of olives and olive oil; Specific components of olive oil and their effects on tissue and body systems
