ABSTRACT
The aim of this study was to find out whether concentrations of oxysterols in pig meat are affected by dietary polyunsaturated fatty acids and vitamin E. 48 growth-finishing pigs were fed diets with either palm oil or soybean oil and vitamin E concentrations of 15, 40 or 200 mg/kg. Concentrations of oxysterols were analyzed in fresh and heat-processed (180 °C, 20 min) meat (M. longissimus dorsi) and in boiled sausage prepared from meat and back fat of the animals. Concentrations of oxysterols in fresh muscle were below 5 nmol/g dry matter; they were independent of the dietary fat type and vitamin E concentration. Heating caused a large increase of oxysterol concentration (up to 55 nmol/g dry matter). This effect was reduced by increasing dietary vitamin E concentration but was independent of the dietary fat. Sausage from pigs fed soybean oil had higher concentrations of oxysterols than sausage from pigs fed palm oil; vitamin E reduced concentrations of oxysterols in sausage from pigs fed soybean oil, but not in sausage from pigs fed palm oil.
