Aspects of the animal food nutritional and nutraceutical value
AbstractThe subject of this paper deals in the description of Italian zootechny with regard to animal food production and their quality. The last is well documented by the presence of a large number of certificated origin marks (53 POD e 11 PGI). Firstly, nutritional quality of food has been described, with particular emphasis for Glucides, Proteins, Lipids, Vitamins and Mineral elements contents and their metabolic role, in the most important food of animal origin: milk, meat, fish and eggs. After, the presence of nutraceutical substances in the same foods has been discussed. In particular the attention has been focused on the metabolic role of ω-3 fatty acids (EPA and DHA) and Rumenic Acid (C 18:2 cis 9 trans 11), the most important isomer of conjugated linoleic acid (CLA). In conclusion has been underlined the importance of nutraceutical substances of animal origin in human balanced diet. Furthermore the fundamental role of Italian zootechny to assure animal food safety and quality has been confirmed.
