不同贮藏条件下武定鸡肌肉肌苷酸及相关核苷酸含量的变化研究
Research on the Changes of Inosinic Acid and its Related Nucleotides Contents in Wuding Chicken Muscle under Different Storage Conditions
摘要
Abstract
The chest muscles of 10 Wuding hens of 150-day-age was selected and was stored at different temperature.The contents of IMP and its related nucleotides at different storage time were determined. The results showed that the contents of IMP reached the highest value 2.002 mg/g after slaughtered 4 h at 18 ℃, and then the contents were significantly decreased after slaughtered for 8 h (P<0.05). The contents of IMP precursors reached the highest value at 2 h (1.46 mg/g) and then decreased gradually. The contents of the IMP degradation products gradually increased with the increase of time. The total contents of the ATP metabolites reached the highest value (5.71 mg/g) at 4 h and then decreased gradually. The K value increased with the increase of time. When the storage temperature was 4 ℃, the contents of IMP first increased and then drop with the time extended and the highest measured value 1.46 mg/g reached after saved 24h. The contents of IMP precursors also had a similar variation rule, and the contents reached the highest value (0.91 mg/g) after 24 h. The contents significantly decreased after the 3th day (P<0.05).The contents of IMP degradation products , the total ATP metabolites and the K value were gradually increased with the increase of time. When Wuding chicken muscle stored at the same temperature, the longer of the storage time, the lower of the IMP contents. The lower of the storage temperature, the slower degradation of IMP, and the longer ATP duration of the whole metabolic process.关键词
