CSIC ORCID ; Landete-Castillejos, Tomás CSIC ORCID ; De Palo, Pasquale | Fecha de publicación: | 2019 | Editor: | John Wiley & Sons | Citación: | Journal of the Science of Food and Agriculture 99(4): 1561-1567 (2019) | Resumen: | [Background]: This study assessed the effect of age (L, less than 27 months old; M, from 27 to 42 months old; H, 43 months and older) on the fatty acid profile, cholesterol content, amino acid composition and mineral content of 150 Iberian wild red deer meat samples. [Results]: Intramuscular fat content increased (P < 0.05) with age (0.05 vs 0.12 vs 0.34% for L, M and H groups respectively), while cholesterol content decreased (P < 0.05) as the slaughter age increased (52.78 vs 48.72 vs 45.34 mg per 100 g meat for L, M and H groups respectively). The slaughter age showed differences among groups for saturated fatty acids, with the highest content in older animals (30.41 vs 34.55 vs 38.21% for L, M and H groups respectively), whereas younger deer displayed the highest polyunsaturated fatty acid levels (50.05 vs 45.24 vs 37.55% for L, M and H groups respectively). The n ‐6/n ‐3 ratio was more favorable (P < 0.05) for young and medium ages compared with that for older animals. In contrast, amino acid profile and mineral content were only slightly affected by age. [Conclusion]: As a general conclusion, wild red deer meat could be considered a good alternative to red meats for human consumption. |
