In the early 1980s, two water-supply systems on the Marine Corps Base Camp Lejeune in North Carolina were found to be contaminated with the industrial solvents trichloroethylene (TCE) and perchloroethylene (PCE). The water systems were supplied by the Tarawa Terrace and Hadnot Point watertreatment plants, which served enlisted-family housing, barracks for unmarried service personnel, base administrative offices, schools, and recreational areas. The Hadnot Point water system also served the base hospital and an industrial area and supplied water to housing on the Holcomb Boulevard water system (full-time until 1972 and periodically thereafter). This book examines what is known about the contamination of the water supplies at Camp Lejeune and whether the contamination can be linked to any adverse health outcomes in former residents and workers at the base.
Over the past ten years, metabolomics strategies have allowed the relative or absolute quantitation of metabolite levels for the study of various biological questions in plant sciences. For fruit studies, in particular, they have participated in the identification of the genes underpinning fruit development and ripening. This book proposes examples of the current use of metabolomics studies of fruit for basic research or practical applications. It includes articles about several tropical and temperate fruit species. The studies concern fruit biochemical phenotyping, fruit metabolism during development and after harvest, including primary and specialized metabolisms, or bioactive compounds involved in fruit growth and environmental responses. The analytical strategies used are based mostly on liquid or gas chromatography coupled with mass spectrometry, but also on nuclear magnetic resonance and near-infrared spectroscopy. The effect of genotype, stages of development, or fruit tissue type on metabolomic profiles and corresponding metabolism regulations are addressed for fruit metabolism studies. The interest in combining other omics with metabolomics is also exemplified.
Consumer acceptance of food is highly dependent on flavour. This important collection reviews the chemical basis of fruit and vegetable flavour and current methods for improving the flavour of fruit and vegetable products. Opening chapters outline the economic importance of flavour in fruit and vegetables. Part one investigates the formation of fruit and vegetable flavour and how it deteriorates after harvest. Part three contains chapters on flavour management during horticultural and postharvest operations. Chapters discuss the possibilities and limitations for flavour improvement by selection and breeding, and the role of maturity for improved fruit and vegetable flavour. Part four concludes the volume with a discussion of emerging trends in flavour manipulation, especially how knowledge of the genetic background of quality attributes can be applied to flavour improvement. With its team of experienced international contributors Fruit and vegetable flavour: recent advances and future prospects is an essential reference for all those working in the food industry concerned with improving flavour in fruit and vegetables. Reviews the chemical basis of fruit and vegetable flavour and current methods for improvement Discusses the possibilities and limitations for flavour enhancement by selection and breeding Illustrates how knowledge of the genetic background of quality attributes can be applied to flavour improvement
Celebrating the founding of the Flavor Subdivision of the Agriculture and Food Chemistry Division of the American Chemical Society, this book provides an overview of progress made during the past 30-40 years in various aspects of flavor chemistry as seen by internationally renowned scientists in the forefront of their respective fields. In addition, it presents up-to-date findings in the areas of flavor chemistry, analytical methods, thermally produced flavors and precursors, enzymatically produced flavors and precursors, and sensory methods and results.
As with nearly all living creatures, humans have always been attracted and intrigued by floral scents. Yet, while we have been manufacturing perfumes for at least 5000 years to serve a myriad of religious, sexual, and medicinal purposes, until very recently, the limitation of our olfactory faculty has greatly hindered our capacity to clearly and ob
