Traceability of Functional Bioactive Compounds in Fresh and Pasteurized Milk Obtained from Goats Fed with Orange Pulp

Abstract

Traceability is the ability to identify and trace the history, distribution, location, and application of products, parts, and materials. A traceability system records and follows the trail as products, parts, and materials come from suppliers and are processed and ultimately distributed as end products (Prache et al, 2002). In this work, were studied the bioactive compounds (total vitamin C, ascorbic acid, total phenols, flavonoids, carotenoids, vitamin A and vitamin E) and antioxidant activity of goat fresh milk and pasteurized one. The goats were fed with a standard diet (control diet) and then with a diet that incorporates orange pulp. The control diet (CD) corresponded with a standard ration (a ration wich provide the energetic and proteic values), daily food for milking animals. From that ration, the Department of Animal Science, from Politechnic University of Valencia replaced the different proportions of the ingredients for incorporating orange pulp diet (OPD). The results of the present study show that the citrus pulp silage mixture used can be fed to goats without any negative effects on the performance of the animals. Results of this study indicate that citrus pulp silage can replace part of the conventional ration of goats, thus lowering the cost of production. The first aim of this study was to compare the two types of goat diets: a standard diet and a diet with orange pulp, by analyzing the bioactive compounds in fresh and pasteurized milk. The results demonstrate that all the bioactive compounds are bigger in the orange pulp diet than in the control diet. The second objective of this study was to analyze the bioavailability and traceability of bioactive compounds in fresh milk.

Evaluation of Dried Citrus Pulp Addition to Total Mixed Ration in Replacement to Corn on Mutton Goat Performance and Health Indices

“…After all, it is industrial waste, cheaper than cereals, resulting in the lowest-cost feed formulation [58]. Chis, Muste and Vidal [59] also stated that adding citrus pulp in animals' rations lowers the cost of production.…”
