3.2.6. Tocopherol content
The levels of tocopherol decreased during storage, mostly due to its scavenging activity against radicals. Initial tocopherol content ranged from 8.67 to 13.80 mg/g sample (data not shown); these results were similar to those obtained by Farvin et al. (2012). At day 0, there were no significant differences in tocopherol levels with different CSP concentration. At day 2, tocopherol levels in 5% CSP samples were higher than the rest of samples, showing at the end of storage (day 3) higher tocopherol content (10.17 mg tocopherol/g muscle) compared to control, 1% CSP and 2% CSP with a concentration of 7.45, 7.11 and 7.37, respectively.
