Book excerpt: This project involves the simultaneous quantification of the fat soluble vitamins D and E in baby food using hypercarb column and the simple general lipid extraction method. The quantification of the vitamin D3 and E were achieved by using a calibration curve with linearity of 25ug/ml - 400ug/ml and r2 of 0.9602 for vitamin D3, whiles the vitamin E was done by using a calibration curve with linearity of 10ug/ml - 200ug/ml and r2 of 0.9941. The r2 value for vitamin D3 was not very accurate which was due to carry over during the calibration analysis, but both calibration curves were very reproducible with % RSD of less than 5%. The % recoveries calculated after the extraction was found to be 149.6 % for vitamin D3 and 111.1% for vitamin E, but the % recovery obtained for vitamin D3 was above the recommended range which was due to co-elution with other vitamins and ingredients.

Available in PDF, EPUB and Kindle. Book excerpt: This book has been written primarily for medical students and junior doctors in clinical practice, but would also be a useful reference for postgraduate students in chemical pathology (clinical biochemistry), laboratory scientists, pathologists and medical laboratory technologists. It covers the field of chemical pathology, the biochemical basis of disease, and provides a basic understanding of the relationship between abnormal biochemical test results and disease states. A rational approach to proper selection and interpretation of biochemical investigations is adopted for each organ system or analyte covered in the 28 chapters. Emphasis is placed on areas and problems most commonly met with in clinical practice. Meant primarily as an introductory study book to the subject rather than as a reference text, the materials have been presented in a clear, condensed format to aid the study process. The written text is amply supplemented with relevant illustrations.

Available in PDF, EPUB and Kindle. Book excerpt: The first demonstration of the existence of a vitamin and the full recognition of this fact are often attributed to the work of McCollum, who found that a sub stance in butterfat and cod-liver oil was necessary for growth and health of ani mals fed purified diets. It became obvious that an organic substance present in microconcentrations was vital to growth and reproduction of animals. Following the coining of the word vitamine by Funk, McCollum named this fat-soluble sub stance vitamin A. We can, therefore, state that vitamin A was certainly one of the first known vitamins, yet its function and the function of the other fat-soluble vitamins had remained largely unknown until recent years. However, there has been an explosion of investigation and new information in this field, which had remained quiescent for at least two or three decades. It is now obvious that the fat-soluble vitamins function quite differently from their water-soluble counter parts. We have learned that vitamin D functions by virtue of its being converted in the kidney to a hormone that functions to regulate calcium and phosphorus metabolism. This new endocrine system is in the process of being elucidated in detail, and in addition, the medical use of these hormonal forms of vitamin D in the treatment of a variety of metabolic bone diseases has excited the medical com munity.

Book excerpt: This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.

Available in PDF, EPUB and Kindle. Book excerpt: Instrumental Methods in Food Analysis is aimed at graduate students in the science, technology and engineering of food and nutrition who have completed an advanced course in food analysis. The book is designed to fit in with one or more such courses, as it covers the whole range of methods applied to food analysis, including chromatographic techniques (HPLC and GC), spectroscopic techniques (AA and ICP), electroanalytical and electrophoresis techniques. No analysis can be made without appropriate sample preparation and in view of the present economic climate, the search for new ways to prepare samples is becoming increasingly important. Guided by the need for environmentally-friendly technologies, the editors chose two, relatively new techniques, the microwave-assisted processes (MAPTM (Chapter 10) and supercritical fluid extraction (Chapter 11). Features of this book: - is one the few academic books on food analysis specifically designed for a one semester or one year course -it contains updated information - the coverage gives a good balance between theory, and applications of techniques to various food commodities. The chapters are divided into two distinct sections: the first is a description of the basic theory regarding the technique and the second is dedicated to a description of examples to which the reader can relate in his/her daily work.

Available in PDF, EPUB and Kindle. Book excerpt: Food products are very complex mixtures consisting of naturally occurring compounds and other substances, generally originating from technological processes, agrochemical treatments, or packaging materials. However, food is no longer just a biological necessity for survival. Society demands healthy and safe food, but it is also increasingly interested in other quality attributes more related to the origin of the food, the agricultural production processes used, the presence or not of functional compounds, etc. Improved methods for the determination of authenticity, standardization, and efficacy of nutritional properties in natural food products are required to guarantee their quality and for the growth and regulation of the market. Nowadays, liquid chromatography with ultraviolet detection, or coupled to mass spectrometry and high-resolution mass spectrometry, are among the most powerful techniques to address food safety issues and to guarantee food authenticity in order to prevent fraud. The aim of this book is to gather review articles and original research papers focused on the development of analytical techniques based on liquid chromatography for the analysis of food. This book is comprised of six valuable scientific contributions, including five original research manuscripts and one review article, dealing with the employment of liquid chromatography techniques for the characterization and analysis of feed and food, including fruits, extra virgin olive oils, confectionery oils, sparkling wines and soybeans.

This book was released on 1998-03-24 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micronutrient malnutrition affects approximately 2 billion people worldwide. The adverse effects of micronutrient deficiencies are profound and include premature death, poor health, blindness, growth stunting, mental retardation, learning disabilities, and low work capacity. Preventing Micronutrient Deficiencies provides a conceptual framework based on past experience that will allow funders to tailor programs to existing regional/country capabilities and to incorporate within these programs the capacity to address multiple strategies (i.e., supplementation/fortification/food-based approaches/public health measures) and multiple micronutrient deficiencies. The book does not offer recommendations on how to alleviate specific micronutrient deficienciesâ€"such recommendations are already available through the publications of diverse organizations, including the U.S. Agency for International Development, the Micronutrient Initiative, World Bank, United Nations Childrens' Fund, and the World Health Organization. Instead, this volume examines key elements in the design and implementation of micronutrient interventions, including such issues as: The importance of iron, vitamin A, and iodine to health. Populations at risk for micronutrient deficiency. Options for successful interventions and their cost. The feasibility of involving societal sectors in the planning and implementation of interventions. Characteristics of successful interventions. The book also contains three in-depth background papers that address the prevention of deficiencies of iron, vitamin A, and iodine.
