The antioxidant parameters analysed were: a- and c-tocopherol, total phenolics compounds (TPC), lipophilic and hydrophilic antioxidant activities (LAA, HAA) (acorn and grass) and condensed and hydrolysable tannins (CT, HT) and protein precipitating capacity (PP) (acorns). To characterise the fatty acid proﬁles, the thirteen major fatty acids were assayed. For the acorns, it was found that there was intra-annual variability in all the antioxidants studied except a-tocopherol, and inter-annual variability in all except the protein precipitating capacity. The fatty acid proﬁle also varied depending on the sampling date and the study year, especially in the saturated fatty acids (SFA) and C18:1 n-9 content. For the grass, there was intraand inter-annual variability in all the antioxidant parameters studied, and in the proportions of the fatty acids C18:0, and C18:1. It could explain variations in the antioxidant and fatty acids composition of Iberian pig tissues from animals raised in different ‘‘montanera” seasons and even in the same ‘‘montanera” season.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier Ltd</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Tejerina, D.</style></author><author><style face="normal" font="default" size="100%">García-Torres, S.</style></author><author><style face="normal" font="default" size="100%">Cabeza de Vaca, M.</style></author><author><style face="normal" font="default" size="100%">Cava, R.</style></author><author><style face="normal" font="default" size="100%">Vázquez, F.

Results showed that morphological characteristics remained constant throughout montanera season. Fungal damage increased, and Curculio sp. and Cydia sp. pests decreased over the course of the montanera season. Dry matter content decreased in both kernel and pericarp (P &lt; 0.001), while the crude fiber and protein contents were not modified. The ash, nitrogen-free extract, and fat contents, however, were also affected by sampling date within a montanera season. With respect to the interannual variability, variations (P &lt; 0.05) were observed in all the variables studied. It is therefore confirmed that there is variability in the sanitary condition and nutritional composition of acorns within the same montanera season and between different years of study. These could explain the differences in the chemical characteristics of Iberian pig tissues from animals raised in different montanera seasons, and even during the same montanera season.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Estévez, M.</style></author><author><style face="normal" font="default" size="100%">Morcuende, D.</style></author><author><style face="normal" font="default" size="100%">Ramírez, R.</style></author><author><style face="normal" font="default" size="100%">Ventanas, J.</style></author><author><style face="normal" font="default" size="100%">Cava, R.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Extensively reared Iberian pigs versus intensively reared white pigs for the manufacture of liver pâté.</style></title><secondary-title><style face="normal" font="default" size="100%">Meat science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Extensive</style></keyword><keyword><style  face="normal" font="default" size="100%">fatty acids</style></keyword><keyword><style  face="normal" font="default" size="100%">Iberian pigs</style></keyword><keyword><style  face="normal" font="default" size="100%">Instrumental colour</style></keyword><keyword><style  face="normal" font="default" size="100%">Iron</style></keyword><keyword><style  face="normal" font="default" size="100%">liver p</style></keyword><keyword><style  face="normal" font="default" size="100%">liver paté</style></keyword><keyword><style  face="normal" font="default" size="100%">White pigs</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2004</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2004///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/22061520</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">67</style></volume><pages><style face="normal" font="default" size="100%">453 - 461</style></pages><isbn><style face="normal" font="default" size="100%">3492725716</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Physico-chemical characteristics and quality traits of the raw ingredients (muscle cuadriceps femoris, liver and adipose tissue) and the pâtés made from extensively reared Iberian pigs and intensively reared white pigs, were evaluated. The differences found between muscles, livers and adipose tissues from Iberian and white pigs influenced the characteristics of the pâtés. Compared to pâtés from white pigs, pâtés from Iberian pigs had a higher content of heme iron (27.5 μg/g vs 11.5 μg/g; p&lt;0.05) and lower content of non-heme iron (27.5 μg/g vs 33.7 μg/g; p&lt;0.05). Pâtés from Iberian pigs exhibited a darker colour (L (∗):18.6 vs 15.9, p&lt;0.05) with less redness (a (∗) values: 9.1 vs 11.3; p&lt;0.05) and yellowness (b (∗) values: 13.1 vs 14.8, p&lt;0.05). Thus, pâtés from white pigs had higher values of chroma (18.6 vs 15.9, p&lt;0.05) and smaller values of hue (52.5 vs 55.2, p&lt;0.05) that those from Iberian pigs' pâtés. In fatty acid composition, pâtés from white pigs had higher proportions of SFA (37.9% vs 32.8%, p&lt;0.05) and PUFA (14.4% vs 9.6%, p&lt;0.05) than pâtés from Iberian pigs and lower percentages of oleic (53.4% vs 43.6%, p&lt;0.05) and total of MUFA (57.5% vs 47.6%, p&lt;0.05). Pâtés from Iberian pigs had a lower n-6/n-3 values (13.2 vs 17.2; p&lt;0.05).</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;accession-num: 22061520</style></notes></record></records></xml>
