Producing tender and flavoursome beef with enhanced nutritional characteristics

Area of Science:

• Animal Science
• Food Science
• Nutritional Science

Background:

• Consumer purchasing decisions for beef are influenced by perceived healthiness, safety, tenderness, juiciness, aroma, and flavor.
• Beef production involves complex interactions between genotype, gender, age at slaughter, and pre-slaughter nutrition.
• Post-slaughter carcass management significantly impacts meat tenderness, often more than pre-slaughter factors.

Purpose of the Study:

• To review recent findings on modifying beef production systems to improve tenderness, flavor, and healthiness.
• To explore the influence of cattle diet on beef flavor and nutritional profile.
• To identify strategies for producing high-quality, healthy beef.

Main Methods:

• Literature review of recent research on beef production systems and quality attributes.
• Analysis of the chemical components contributing to beef flavor.
• Examination of the relationship between cattle diet composition and beef fatty acid profiles.

Main Results:

• Carcass management post-slaughter is a critical factor for beef tenderness.
• Beef flavor chemistry is intricate, with over 140 identified volatile components.
• Increasing grass in cattle diets reduces saturated fatty acids and increases beneficial fatty acids like n-3 polyunsaturated fatty acids and conjugated linoleic acid.
• Lean beef typically contains 25-50g/kg intramuscular fat, qualifying it as a low-fat food.

Conclusions:

• Beef production systems can be optimized through strategic carcass management and dietary adjustments.
• Cattle diet offers a viable method to enhance beef flavor and nutritional value, aligning with human dietary recommendations.
• Future opportunities exist to produce tender, flavorful beef with improved fat profiles, including lower fat content and increased beneficial fatty acids.
