Selected freshness indices of skin and wings from organic chicken packaged in modified atmosphere

Popis výsledku v původním jazyce

This study is part of a project aiming to optimize storage conditions for organic chicken meat. Selected indices of skin and wings from organic chicken were evaluated. A total of 24 samples were packaged in MAP-O-2 (80% O-2/20% CO2), 24 samples in MAP-N-2 (70% N-2 /30% CO2) and 48 samples as a control. The samples were analysed on days 2, 7, 10 and 14 of storage during a 14-day storage period at 2 +/- 2 degrees C. The surface colour of skin (L*a*b*), ammonia content, thiobarbituric acid reactive substances content (TBARS) and antioxidant capacity were assessed. The lightness values (L*) for chicken skin in MAP-O-2 were increased on days 7 and 10 of the storage period, and were significantly (P &lt; 0.05) higher than in the samples in MAP-N-2 and the control. Significant increases of TBARS were observed in the samples in MAP-O-2 from day 7 and these values continued to increase until the end of the storage period. The antioxidant capacities of the samples in MAP-O-2 were mostly lower than those of the samples in MAP-N-2. Our results indicate that MAP-O-2 only had a positive effect on skin colour, whereas MAP-N-2 maybe preferable for shelf-life prolongation.
