Resumo: | ABSTRACT: The purpose of this study was to evaluate the effects of feeding pigs with diets containing increasing levels of Brazilian red pepper essential oil ( Schinus terebinthifolius Raddi) on the physical attributes, fatty acid profile and oxidative stability of precooked meat. Seventy-two weanling pigs (5.7±0.8kg) were allotted in a completely randomized block design experiment with four treatments, six replicates per treatment, and three animals per experimental unit (pen). Animals were fed with a basal diet supplemented with 0, 500, 1,000, or 1,500mg kg-1 Brazilian red pepper essential oil during the 35-d experimental period. At the end of the experiment, one animal per experimental unit (16.4±2.2kg) was slaughtered to sample Longissimus dorsi muscle for analysis. Dietary supplementation of Brazilian red pepper had no effect (P&gt;0.05) on pork meat color, pH, cooking loss and shear force. Inclusion of essential oil in the diet provided a linear increase (P&lt;0.05) of the saturated fatty acids content of L. dorsi, especially myristic (C14:0) and stearic (C18:0) fatty acids. Utilization of essential oil in pig diets reduced significantly the production of secondary lipid oxidation compounds measured as TBARS in raw pork meat (P&lt;0.001) and immediately after cooking (P&lt;0.001). However, during 8-d storage assay, the addition of essential oil in the diet did not protect pork meat lipids from oxidation. Therefore, Brazilian red pepper added to pig diets increased the saturated fatty acids content and reduced lipid oxidation in fresh meat and short-term heat treatment without affecting pork meat physical attributes.
