Book Synopsis Headspace Analysis of Foods and Flavors by : American Chemical Society. Meeting
Download or read book Headspace Analysis of Foods and Flavors written by American Chemical Society. Meeting and published by Springer Science & Business Media. This book was released on 2001-08-31 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Headspace gas analysis is an analytical technique that has been successfully applied to food flavors for over 20 years but has experienced a resurgence of interest and innovation in recent years. In its truest form, headspace analysis represents the direct collection and analysis of the mixture of vapors in the space immediately above a food or beverage. The technique offers several advantages for workers interested in how a product smells and ultimately tastes. It offers the advantages of speed, simplicity, and, more importantly, represents the aroma profile a consumer is likely to experience just before consuming the product. Since only volatile components are collected, the sample is totally free of nonvolatile residues which commonly plague comparison liquid-liquid extracts of the same product. This is the first book devoted to headspace analysis in foods and beverages in more than 20 years. The publication contains chapters on the basic theory of headspace analysis, as well as the theory and application of newly developed headspace techniques, such as solid phase micro extraction, SPME and electronic noses. New concentrating and desorption techniques are described in addition to a raft of food applications including tomato and citrus juices, alcoholic beverages, baguettes, dairy products, lipids, grill flavoring, baked potato, and meat. Chapters on off-flavors as well as aroma-food matrix interactions are also included. "This is the bible of headspace analysis. If you are involved in, or planning on becoming involved, or want to learn more about, this incredible subject , then buy this book immediately!" – Aubrey Parsons, governing council member, International Union for Food Science and Technology
Book Synopsis Multivariate Calibration by : Harald Martens
Download or read book Multivariate Calibration written by Harald Martens and published by John Wiley & Sons. This book was released on 1992-08-07 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multivariate Calibration Harald Martens, Chemist, Norwegian Food Research Institute, Aas, Norway and Norwegian Computing Center, Oslo, Norway Tormod Næs, Statistician, Norwegian Food Research Institute, Aas, Norway The aim of this inter-disciplinary book is to present an up-to-date view of multivariate calibration of analytical instruments, for use in research, development and routine laboratory and process operation. The book is intended to show practitioners in chemistry and technology how to extract the quantitative and understandable information embedded in non-selective, overwhelming and apparently useless measurements by multivariate data analysis. Multivariate calibration is the process of learning how to combine data from several channels, in order to overcome selectivity problems, gain new insight and allow automatic outlier detection. Multivariate calibration is the basis for the present success of high-speed Near-Infrared (NIR) diffuse spectroscopy of intact samples. But the technique is very general: it has shown similar advantages in, for instance, UV, Vis, and IR spectrophotometry, (transmittance, reflectance and fluorescence), for x-ray diffraction, NMR, MS, thermal analysis, chromatography (GC, HPLC) and for electrophoresis and image analysis (tomography, microscopy), as well as other techniques. The book is written at two levels: the main level is structured as a tutorial on the practical use of multivariate calibration techniques. It is intended for university courses and self-study for chemists and technologists, giving one complete and versatile approach, based mainly on data compression methodology in self-modelling PLS regression, with considerations of experimental design, data pre-processing and model validation. A second, more methodological, level is intended for statisticians and specialists in chemometrics. It compares several alternative calibration methods, validation approaches and ways to optimize the models. The book also outlines some cognitive changes needed in analytical chemistry, and suggests ways to overcome some communication problems between statistics and chemistry and technology.
