The effects of cooking the meat and its subsequent refrigeration were also studied. When the content of primary oxidation compounds of the oil was high, rabbit plasma, liver, and meat R-tocopherol content was reduced and meat susceptibility to oxidation increased. The addition of oil with a high content of secondary oxidation compounds (oil heated at 140 'C, 31 h) to feed also led to an increase in meat susceptibi- lity to oxidation, although it presented an R-tocopherol content similar to that of nonheated oil. Feed supplementation with R-tocopheryl acetate increased tissue R-tocopherol content and improved the oxidative stability of liver and meat. However, in the latter, it was less effective when oil heated at 55 'C was added.8 p.application/pdfeng(c) American Chemical Society, Books and Journals Division], 2010Olis vegetalsPinsosConillsSuplements nutritiusZincReacció d'oxidació-reduccióVegetable oilsFeedsRabbitsDietary supplementsZincOxidation-reduction reactioninfo:eu-repo/semantics/article5844512014-03-28info:eu-repo/semantics/openAccess
