What Is the Science Behind Wild Game Meat?
Type I - slow-twitch, oxidative Type IIa - fast-twitch, oxidative-glycolytic Type IIx - fast-twitch, glycolytic Wild game - higher Type I percentage Domestic animals - more Type II fibers Exercise effect - wild animals more active
Cooking Implications:
Slow-twitch - requires longer cooking Connective tissue - more in wild game Tenderizing - needs different approach Heat sensitivity - overcooks quickly Moisture loss - rapid dehydration Collagen content - varies by muscle
Fat Distribution and Composition
Marbling Differences:
Intramuscular - fat very low in wild game Subcutaneous - fat varies seasonally Intermuscular - minimal in wild animals Domestic comparison - higher overall fat Seasonal variation - pre-winter fat storage Diet impact - affects fat composition
Fatty Acid Profiles:
Omega-3 - higher in wild game Omega-6 - lower than grain-fed Saturated fat - generally lower Polyunsaturated - higher percentages Conjugated linoleic - acid present Diet dependent - natural forage vs. grain
pH and Meat Quality
Post-Mortem pH:
Initial pH - 7.0-7.4 in living muscle Lactic acid - production lowers pH Ultimate pH - 5.4-5.8 normal Stress factors - affect pH decline Wild game - often higher stress pH impact - water-holding capacity
Quality Indicators:
Dark, firm, dry - high pH meat Pale, soft, exudative - low pH meat Water holding - capacity affected Color stability - pH dependent Shelf life - pH influences Cooking behavior - pH effects
Protein Structures
Myosin and Actin:
Contractile proteins - muscle function Cross-linking - affects tenderness Heat denaturation - cooking changes Wild game - different ratios Calcium pumps - affect rigor Enzyme activity - post-mortem changes

Color Chemistry
Myoglobin Content:
Oxygen-binding - protein Color determinant - red meat color Wild game - typically higher Age correlation - older animals darker Exercise effect - working muscles Species variation - significant differences
Color Changes:
Oxymyoglobin - bright red, fresh Deoxymyoglobin - purple, vacuum Metmyoglobin - brown, oxidized Heat effects - cooking color changes pH influence - color stability Oxygen exposure - color development
Flavor Compounds
Volatile Compounds:
Lipid oxidation - products Maillard reaction - browning flavors Amino acid - breakdown Diet influence - flavor precursors Wild forage - unique compounds Seasonal variation - flavor changes
Non-Volatile Taste:
Nucleotides - umami compounds Amino acids - taste active Minerals - taste contribution Organic acids - tartness Exercise metabolites - flavor impact Stress compounds - affect taste
Nutritional Composition
Protein Quality:
Complete proteins - all amino acids Biological value - high utilization Digestibility - excellent Amino acid - profile optimal Muscle composition - affects quality Exercise effect - protein density
Mineral Content:

Rigor Mortis Process
Biochemical Changes:
ATP depletion - energy loss Calcium release - muscle contraction pH decline - lactic acid Protein binding - cross-links form Time course - temperature dependent Resolution - natural tenderizing
Practical Implications:
