1 p, 2.4 MB Oxidation in fresh and spray-dried omega 3 and omega 6 fatty acid enriched eggs. Vitamin E and canthaxantin / Galobart i Cots, Jaume ; Barroeta, Ana Cristina (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Baucells Sánchez, María Dolores (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Guardiola Ibarz, Francesc
Consumption of products enriched in co3 fatty acids such broiler meat or eggs are associated to health benefits. However, the increase in unsaturation of the lipids present in the food may cause a reduction in its oxidative stability, decreasing its nutritive and organoleptic value and producing toxic lipid oxidation products. [...]

3 p, 229.2 KB Vitamin E levels and lipid oxidation in ω3 fatty acids enriched eggs / Galobart i Cots, Jaume ; Barroeta, Ana Cristina (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Baucells Sánchez, María Dolores (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Guardiola Ibarz, Francesc
With the aim to establish the required amount of α-tocopherol to effectively prevent lipid oxidation in w3 FA enriched eggs, a trial was conducted with 2XX laying hens. Birds were randomly assigned to four treatments resulted from supplying a basal diet containing 5% of linseed oil (diet: 65% PUFA, 34,5% m3) with 0 (C), 50 (50E), 100 (I00E) or 200 (200E) ppm of alpha-tocopherol acetate.

Departament de Ciència Animal i dels Aliments) ; Baucells Sánchez, María Dolores (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Guardiola Ibarz, Francesc.
A trial with 192 laying hens was conducted to study the effect of Vitamin E and Canthaxanthin as antioxidants in w3 either w6 fatty acid (FA) enriched eggs. The animals were randomlyassigned to eight treatments resulted from the supplementation of a basal dietcontaining5% of linseed oil (L) orsunfloweroil (S) with 200 ppm ofutocopheryl acetate (LE and SE), 5ppm of Canthaxathin(LC and SC) or both (LEG and SEC).

1 p, 1.8 MB Effect of Natural Antioxidants on the Oxidative Stability of Eggs / Galobart i Cots, Jaume ; Barroeta, Ana Cristina (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Baucells Sánchez, María Dolores (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Codony, Rafael
Due to the increase in the production of co3 PUFA enriched eggs, prevention of lipid oxidation in such products became more important. Dietary supplementation with alpha-tocopherol has been reported to increase the oxidative stability of animal products (Lauridsen et al. [...]

1 p, 1.5 MB Evolución de la concentración de a-tocoferol en huevos enriquecidos en ácidos grasos poliinsaturados / Galobart i Cots, Jaume ; Barroeta, Ana Cristina (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Baucells Sánchez, María Dolores (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments)
Aumentar el contenido en ácidos grasos poliinsaturados (AGPI) a>3 del huevo no es la única posibilidad de modificar y mejorar su valor nutritivo. El enriquecimiento de los huevos en a-tocoferol asegura una mayor estabilidad a la oxidación así como un aporte extra de vitamina E en el alimento. [...]

1 p, 2.3 MB Vitamin E levels and lipid oxidation in omega 3 fatty acids enriched eggs / Galobart i Cots, Jaume ; Barroeta, Ana Cristina (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Baucells Sánchez, María Dolores (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Guardiola Ibarz, Francesc
It has been demonstrated that high amounts of a-tocopherol added to the layer's diet (above 200 ppm) have a protective effect on egg lipid oxidation. However it is very important to establish the minimum levels of a-tocopherol needed in diets not only to effectively prevent lipid oxidation in animal products but also to be acceptable economically.
