Extract

Supranutritional supplementation of cattle with vitamin E has improved the colour and lipid stability of beef. Grass-fed cattle have muscle vitamin E concentrations which are 2 to 3 times greater than unsupplemented concentrate-fed cattle (Lanari et al., 2002) but also have higher concentrations of the highly oxidisable long chain n-3 polyunsaturated fatty acids (Nuernberg et al., 2005). The objective was to compare the oxidative stability of grass-with concentrate-fed beef, both minced and intact, and to determine if supplemental vitamin E can increase the oxidative stability of such beef in high oxygen packaging.
