This document discusses the composition and structure of meat. It states that meat is composed primarily of water (75%), protein (20%), and fat (up to 5%). The structure of meat is determined by muscle fibers bound together by connective tissue. Aging meat involves holding it in coolers for an extended period of time to naturally tenderize it. There are two main aging methods - wet aging which involves vacuum packing smaller cuts, and dry aging which exposes the meat to air on all sides without packaging. The document also provides an overview of variety meats, also known as offal, which are organs and glands not part of the dressed carcass.

TLE – GRADE 10

2. Composition and Structure

3. A. COMPOSITION:

4. 1. Water
•Water is about 75
percent of muscle
tissue.

5. 2. Protein
Protein is an important nutrient
and the most abundant solid
material in meat. About 20
percent of muscle tissue is
protein.

6. 3. Fat
•Fat accounts for up to 5
percent of muscle tissue.

7. 4. Carbohydrate
•It is important, however,
because it plays a necessary
part in the complex reaction.

8. B. STRUCTURE

9. 1. Muscle Fibers
•These determine the
texture or grain of a
piece of meat.

10. 2. Connective Tissue
•Muscle fibers are bound
together in a network of
proteins called connective
tissue.

13. C. AGING

14. 1. Green
meat is meat
that has not
had enough
time to
soften. It is
tough and
relatively
flavorless.

15. 2. Aging
•Holding meats in coolers
under controlled conditions
to provide time for this
natural tenderizing.

16. Methods of Aging:
1. Wet aging - Broken down into
smaller cuts and enclosed in plastic
vacuum packs.
2. Dry aging - The meat is not
packaged or wrapped, and it is exposed
to air on all sides.

17. Methods of Aging:
Wet aging Dry aging

18. Cooking Variety Meats

19. •Variety meats, also known as
offal, include the organs,
glands, and other meats that
don’t form a part of the dressed
carcass of the animal.
