| 摘 要： | 为分析鳙和棕点石斑鱼贮藏过程中ATP关联产物含量的变化,本研究以高氯酸溶液作为蛋白沉淀剂,运用高效液相色谱法(HPLC),分析(4±1)°C和(0±1)°C贮藏条件下鳙和棕点石斑鱼体内6种ATP关联化合物含量的变化。结果显示,(4±1)°C条件下,2种鱼体内的ATP都快速降解;ADP、AMP含量则始终较低;IMP含量呈先快速上升后缓慢下降的趋势;鳙体内Hx R含量相对较高,棕点石斑鱼体内Hx R含量较少;Hx在4 d后即开始大量生成。在(0±1)°C条件下,2种鱼肉中ATP同样很快降解,ADP、AMP含量少;IMP降解速率变缓;2种鱼中Hx R生成和分解速率皆变缓;Hx生成速率较为平稳。鳙以IMP、Hx R为限速步骤,棕点石斑鱼以IMP为限速步骤。研究表明,不同的贮藏温度对ATP的降解影响较小,但对其关联产物的变化速率有较大影响,且不同鱼种间ATP关联产物降解规律也有所不同。
