Muscle tissue is composed of: Water (about 75%) Protein (about 20%) Fat (up to 5%) Other elements, including carbohydrate, in small quantities Muscles consist of muscle fibers held together in bundles by connective tissue. Composition and Structure The tenderness of a piece of poultry is related to connective tissue. Connective tissue increases with: Use or exercise of the muscle. Maturity or age of the animal or bird. Use or exercise is of less concern in poultry. Maturity is a major consideration when selecting poultry. Composition and Structure Maturity and Tenderness Young, tender birds are cooked by dry-heat methods, such as broiling, frying, and roasting, as well as by moist heat methods. Older, tougher birds need slow, moist heat to be made palatable.
