Lean meat consists of thin muscle fibers bound in bundles, which determine the texture or grain of the meat. Fine-grained meat has small fibers, while coarse-textured meat has large fibers.

The objectives for this lesson include identifying the market forms of meat, enumerating the structure and composition of meat, and valuing the importance of understanding meat composition to produce quality meat products.

Learners are asked to consider what recipes they usually prepare with meat and whether they consider the cuts when buying meat, and why.

This section explores different market forms of meat, including fresh meat (recently slaughtered, not preserved), chilled meat (placed in a chiller or slightly cold), cured meat (treated with curing agents like salt, sodium nitrate, sugar, and spices), processed meat (altered to improve shelf life, taste, or texture), dried meats (dehydrated), and canned meat (cooked and only requires reheating).

Water constitutes about 75% of muscle tissue. Shrinkage during cooking is a significant concern as it leads to weight and profit loss, emphasizing the importance of understanding water content in meat and poultry.

Protein makes up about 20% of muscle tissue. It coagulates when heated, resulting in firmer meat and moisture loss. Coagulation is directly related to the meat's doneness.

Fat accounts for about 2-5% of muscle tissue. Fat contributes to juiciness (marbling and surface fats), tenderness (marbling separates muscle fibers), and is the main source of flavor in meat. Adding surface fat is known as 'farting'.

Connective tissue is a network of proteins binding muscle fibers. It is tough, especially in muscles that are exercised more or in older animals. There are two main types: collagen (white connective tissue that dissolves with long, slow moist cooking methods) and elastin (yellow connective tissue that is not broken down by cooking but can be softened by pounding, slicing, or grinding).

Learning Task 4 requires a brief explanation of how to market meat, including tips for buying quality meat. The performance task involves creating a photo collage of different market forms of meat using available home materials and writing an insight about the lesson.
