Analysis and Evaluation of Nutritional Components of Thigh Muscles of Wuliang Mountain Black-Boned Chicken
摘要
Abstract
The nutrient compositions of thigh muscles of Wuliang Mountain black-boned chickens of both sexes were measured and compared, and their nutritional values were evaluated. The results showed that (1) the crude protein content of thigh muscles of Wuliang Mountain black-boned chicken was (23.02 ± 0.69)％, ash content (1.25 ± 0.06)％, crude fat content (2.00 ± 0.97)％, and moisture content (73.63 ± 1.29)％; (2) the total amount of 17 amino acids in freeze-dried powder of thigh muscles was (82.59 ± 4.30)％, the total amount of umami amino acids (28.78 ± 1.56)％, and the total amount of essential amino acids (34.08 ± 1.83)％, the proportion of essential amino acids in total amino acids (41.26 ± 0.52)％, and the ratio of essential amino acids to non essential amino acids (70.26 ± 1.52)％, suggesting well-balanced amino acid composition; (3) the total amount of 18 fatty acids in the freeze-dried powder was (33.88 ± 9.41) mg/g, essential fatty acids (10.21 ± 2.89) mg/g, saturated fatty acid (14.13 ± 4.41) mg/g, unsaturated fatty acid (19.75 ± 5.22) mg/g, and unsaturated fatty acids constituted over 50％ of the total fatty acids; (4) the contents of P, Zn, Mg, Ca, Fe and Cu in fresh chicken thigh muscles were (721.25 ± 294.75), (11.40 ± 1.94), (240.03 ± 63.06), (24.28 ± 5.56), (14.94 ± 2.76), (1.51 ± 0.85) mg/kg, respectively; and (5) differences in the nutrient composition of thigh muscles were observed between the sexes. The water content, the total amount of 17 amino acids, flavor amino acids, essential amino acids and phosphorus in thigh muscles of male chickens were significantly higher (P < 0.05 or P < 0.01) than those of female chickens, and an increase was also observed in score of ratio coefficient of amino acid (SRCAA). But the opposite was observed for the contents of crude protein, ash, saturated fatty acids, monounsaturated fatty acids and zinc (P < 0.05 or P < 0.01).关键词
