Poultry must be prepared according to approved specifications and standards. Quality refers to properties like proportion of meat and bone and freedom from defects. Grading involves evaluating poultry against standards to determine quality. Many factors are considered, including conformation, fleshing, fat covering, feathers, and cuts or breaks. Poultry can be cut into various parts like halves, quarters, breasts, wings, and boneless pieces according to standard procedures. Salt is an effective preservative that works by drawing water out of food to dry it and killing microbes through osmotic pressure.
