Every country in the world is concerned with the nutritional status of its population and in utilizing its natural food resources in the most effective way possible. Surveys based on food intakes and food compositional data are being conducted with the object of establishing recommended intakes of vitamins. These recommendations are constantly being changed as new knowledge comes to light. Analytical techniques using physicochemical and microbiological methods have been largely developed to determine the total vitamin content of a food commodity or diet using the most rigorous extraction method commensurate with the stability of the vitamin. The extraction procedures frequently involve prolo...
"Offers comprehensive coverage of the latest toxicological, technological, and nutritional developments in both natural and synthetic antioxidants used in the food industry. Explores the sources of antioxidants, antioxidant classification, synergism, degradation in food systems, and techniques for identification."
Antioxidants are present naturally in virtually all food commodities, providing them with a valuable degree of protection against oxidative attack. When food commodities are subjected to processing, such natural antioxidants are often depleted, whether physically, from the nature of the process itself, or by chemical degradation. In conse quence, processed food products usually keep less well than do the commodities from which they originated. Ideally, food producers would like them to keep better. This objective can often be achieved by blending natural products rich in antioxidants with processed foods, or by using well recognised antioxidants as food additives. In order to understand thei...
Abstract: A detailed reference text for human and animal nutritionists, dieticians, clinicians, biochemists, and interested lay people provides a relatively brief, but authoritative and comprehensive source of information. Fifteen chapters by various authorities on particular vitamins cover nutritional, biochemical, and clinical aspects of vitamins A, B6, B12, C, D, E, K, thiamin, riboflavin, nicotinic acid and nicotinamide, biotin, pantothenic acid, folic acid, choline and carnitine, including a special chapter on substances lacking vitamin status. Tabular data and illustrations are presented throughout the text. (wz).
A two-volume set which traces the history of food and nutrition from the beginning of human life on earth through the present.
