Although supplementation of the diet with vit. E
(2025 mg/day for 136 days) inhibited lipid oxidation, as
shown by TBA values, no signi®cant eect of this
treatment was found on the colour stability of fresh or
aged LT muscle. In PM muscle SUP beef oxygenated
less, which resulted in lower a values in the ®rst part of
the storage period. After aging of beef for 26 days col-our stability was decreased and more variable than in resh muscle. Vit. E uptake by the CON group was
relatively high (approx. 330 mg/day), which might have
been of influence on the results.
