Meat Quality and Tenderness Summary

Overview of Meat Quality and Tenderness

  • Focus on pre-slaughtering, slaughtering, and post-slaughtering processes.

Slaughtering Procedures

  • Permit Requirements: Health certificates, reports (ante mortem and post mortem).

  • Importance of inspections: Removes unhealthy products and prevents the spread of zoonotic diseases.

Meat Value Chain

  • Meat production is an integrated system from farm to table.

Animal Handling Prior to Slaughter

  • Key Activities: Transportation, resting, feeding, watering, fasting, and stunning.

  • Resting: Reduces stress and improves glycogen content in muscles.

  • Fasting: Reduces gut content for better hygiene, aids in pH control post-mortem.

Slaughtering Techniques

  • Stunning Methods: Mechanical, electrical, and gas. Each method affects meat quality differently.

    • Electrical: Immediate stun but can affect carcass quality.

    • Gas: Causes discomfort but results in improved quality.

  • Humane Method: Involves stunning, followed by bleeding the animal efficiently.

Post-Slaughter Processes

  • Evisceration: Removal of internal organs without puncturing viscera.

  • Carcass Washing: Essential for hygiene and appearance pre-chilling.

  • Refrigeration: Crucial to extend shelf life, optimize temperature and humidity during storage.

  • Good practices: Control of conditions during chilling prevents microbial growth.

Meat Quality Attributes

  • Tenderness Factors: Collagen content, processing methods, and rigor mortis.

  • Flavor Development: Influenced by cooking methods and chemical compound reactions during cooking.

  • Water Holding Capacity: Important for juiciness; poor WHC leads to dry meat.

Effects of Improper Handling

  • Can lead to animal stress, injuries, reduced quality (e.g., PSE and DFD meats).

    • PSE: Pale, soft, exudative meat; poorer marketability.

    • DFD: Dark firm dry meat; associated with stress before slaughter.

Key Reminders

  • Maintain humane treatment of animals to ensure quality and comply with halal standards.

  • Focus on proper handling and hygiene to prevent contamination and preserve meat quality.
