Meats Commonly Having Intra-muscular Fat

Intra-muscular fat is common in:

Correct Answer: Both Mutton and Beef

Intra-muscular fat (marbling) is common in both mutton and beef.

Intramuscular Fat by Species

• Mutton — Maximum intramuscular fat among all meats (highest marbling)
• Beef — Significant intramuscular fat (basis of the beef grading system — Prime > Choice > Select based on marbling)
• Pork — Has intramuscular fat too, but subcutaneous fat predominates
• Veal — NO intramuscular fat (very lean)
• Poultry (Chicken) — Mostly subcutaneous fat; minimal intramuscular fat
• Chevon — Very little intramuscular fat (very lean, very firm)

Why Marbling Matters

• Intramuscular fat melts during cooking, basting the muscle fibres from within → more tender, juicy, flavourful meat.
• Wagyu/Kobe beef is famous for extreme marbling — iodine value and fat content are extremely high.
