Notes:
Raw and cooked pigs'feet and tails were compared for yield, proximate composition, mineral, vitamin, amino acid, protein efficiency ratio (PER) (calculated from amino acid compositions), saturated and polyunsaturated fats; and cholesterol content, The raw yields for pigs' feet and tails were 42.2 and 69.9%, respectively. Corresponding values for cooking losses were 9.4 and 13.0%. Cooking the two products resulted in significant increases in moisture content. Cooked pigs' feet produced significant losses of protein, fat, ash, and caloric values, while cooked pigs' tails showed none. Cooked pigs' feet and tails resulted in some changes in minerals, vitamins, amino acids, and polyunsaturated fat. There was no significant difference between the saturated fats and cholesterol in the raw and cooked products. The PER values of pigs' feet were lower than those of pigs' tails.
