Abstract:Crossed pigs were fed a control diet (with 0.3 mg/kg sodium selenite+1.5% soybean oil) or organic selenium diets (0.3 mg/kg Se-Yeast +1.5% soybean oil or linseed oil, 0.5 mg/kg Se-Yeast+1.5% soybean diet) to investigate the effects on selenium deposition in loin muscle, fatty acid profile, properties of myofibrillar and processed meat products. The organic diets increased muscular selenium content up to 54% (P<0.05) compared to the control diet. Linseed oil supplemented in the pig diet improved n-6/n-3 ratio, the solubility and gelatin strength of myofribrillar (P<0.05), without affecting the microstructure and sensory characters of Frankfurters. The high level of organic selenium supplementation inhibited the lipid oxidation of Frankfurters from d 7 to d 12. Hence, dietary organic selenium and linseed oil supplementation have some enhancement in Se-enriched meat production and processing.
