Notes on Meat Preparation and Cooking

Technology and Livelihood Education: Cookery 10 - Preparing and Cooking Meat

Definition of Meat: Meat is defined as the flesh of cattle, sheep, and pigs. It includes specific types such as beef (from cattle), veal (from young calves), lamb (from young sheep), and pork (from pigs).
Composition of Meat: Meat is composed of four major constituents: water, protein, fat, and some minerals and vitamins.
- Water Content: Approximately 70% of muscle tissue in meat consists of water.
- Protein Content: About 20% of muscle tissue is protein. When heated, proteins coagulate, meaning they become firmer and lose moisture. The meat is considered done when protein has been adequately coagulated.
- Fat Content: Roughly 5% of muscle tissue is fat, which contributes significantly to the meat's juiciness, tenderness, and flavor.
  - Juiciness: Associated with marbling (fat within muscle tissue) and surface fats that prevent moisture loss during cooking.
  - Tenderness: Marbling separates muscle fibers, facilitating easier chewing.
  - Flavor: Fat is the primary source of flavor in meat.
- Carbohydrates: Carbohydrates play a critical role in the Maillard reaction—the complex chemical reaction that occurs when meat is browned through cooking methods like roasting, broiling, or sautéing. They are essential for achieving the desirable flavor and appearance of browned meats.

Primal Cuts: Beef is divided into large sections called primal cuts, these are further broken down into steaks and retail cuts.
Sides of Beef: A side of beef refers to one half of the carcass, which is split down the backbone and then divided into forequarter and hindquarter sections.
Popularity: Beef is a widely consumed form of red meat around the globe, sought after for its flavor and versatility in cooking.

Derived From: Pork is meat obtained from pigs and is classified as red meat, though it typically has less fat content compared to beef.
Primal Cuts: Similar to beef, pork is also divided into primal cuts, which are then made into retail cuts.

Names: Sheep meat is referred to as lamb when it comes from immature sheep and mutton when it comes from mature sheep.
Classification: It is classified as red meat and is a staple in many cuisines around the world.

Protein Percentage: Constitutes about 20% of muscle tissue.
Coagulation: During cooking, proteins coagulate, resulting in a firmer texture and moisture loss.

Percentage of Fat: Composed of approximately 5% fat.
Roles of Fat:
- Juiciness: Enhances juiciness, protects against drying during cooking.
- Tenderness: Increases tenderness by separating muscle fibers.
- Flavor: Serves as the primary flavor source in meat.

Importance: Carbohydrates contribute to the Maillard reaction during cooking, crucial for flavor and color development in browned meats.

Lean Meat Structure: Comprising long, thin muscle fibers in bundles, affecting the texture or grain of the meat.
Texture Types:
- Fine-grained Meat: Consists of smaller fibers.
- Coarse-textured Meat: Contains larger fibers.

Definition: A network of proteins that binds muscle fibers.
Types:
- Collagen: The white connective tissue that dissolves during long, slow cooking, turning tough cuts tender.
- Elastin: The yellow connective tissue that remains tough and does not dissolve during cooking; can only be tenderized through mechanical means such as pounding or grinding.

Washing: Wash meat primarily when it comes into contact with blood. After washing, dry thoroughly with absorbent kitchen paper.
Skinning: Most commercially available meat is already skinned.
Dicing: Cutting meat into cubes for dishes like casseroles and curries.
Trimming: Involves removing excess fat and gristle for improved appearance, maintaining even thickness, and maximizing meat retention.
Slicing: Cut across the grain to avoid toughness, particularly for tougher cuts like steak.
Seasoning: Adding salt and pepper to enhance flavor. Salt should be added post-browning to prevent moisture loss.
Coating: Two standard coating methods involve using flour or breadcrumbs, which require an egg wash in between to adhere properly.
- Flour Coating: Applied before cooking to prevent stickiness.
- Breadcrumb Coating: Requires the flour to first coat the meat, followed by an egg wash and finally breadcrumbs.

Pork: Meat from domesticated pigs; typically high in fat. Slaughtered before one year for tenderness.
Beef: Meat from cattle over one year of age.
Karabao Beef: Meat from the carabao.
Lamb: Meat from domesticated sheep, tender due to the animal's diet and age at slaughter.
Chevon: Meat from goats or deer.
Veal: The flesh of a young calf, typically around four to five months old, highly regarded for its tenderness.

Final Note: Understanding these fundamental aspects of meat is crucial for proper preparation and cooking, enhancing both safety and flavor enjoyment in culinary practice.
