研究了新鲜鱼油（FFO）和氧化鱼油（OFO）饲料对褐点石斑鱼（Epinealus fuscoguttatus × Escherichia coli）肌肉品质的影响。lanceolatu）。用含9%FFO或OFO的饲料饲养杂交石斑鱼60 d。分别于0、30、60 d采集肌肉样品，测定肌肉各项指标。随着摄食时间的延长，石斑鱼肌肉中丙二醛（MDA）、活性氧（ROS）、总胆固醇（TC）和甘油三酯（TG）逐渐积累，OFO组尤为明显。FFO组肌肉中总饱和脂肪酸（SAFA）显著降低，总多不饱和脂肪酸（PUFA）显著升高; 60 d时，OFO组肌肉中SAFA和单不饱和脂肪酸（MUFA）含量显著高于FFO组，而PUFA（尤其是C22：5 n3、C22：6 n3）含量显著低于FFO组。摄食OFO 60 d后，石斑鱼肌肉中挥发性化合物的多样性降低，总酯含量显著降低，总醛和总芳烃含量增加。此外，OFO饲料的摄入显着降低石斑鱼肌肉中的部分生长因子和抗氧化基因的mRNA表达。因此，鱼油中MDA含量的增加和PUFA的氧化酸败可导致石斑鱼肌肉氧化损伤，导致品质和风味的劣化。
The aim of the study was to investigate the effects of fresh fish oil (FFO) and oxidized fish oil (OFO) diets on the muscle quality of hybrid grouper (♀ Epinephelus fuscoguttatus × ♂ E. lanceolatu). Hybrid grouper were fed with diets containing 9% FFO or OFO for 60 days. Muscle sample were collected at 0, 30, and 60 days and the selected indexes of muscle were measured. Malondialdehyde (MDA), reactive oxygen species (ROS), total cholesterol (TC) and triglycerides (TG) in grouper muscle accumulated gradually with prolonged ingestion time, especially OFO group. Total saturated fatty acids (ΣSAFA) was significantly reduced and total polyunsaturated fatty acids (ΣPUFA) was significantly increased of muscle in FFO group; meanwhile, the muscle ΣSAFA and monounsaturated fatty acids (ΣMUFA) contents in the OFO group were significantly higher than those in the FFO group and the ΣPUFA (especially C22:5n3, C22:6n3) contents was significantly lower than that in the FFO group at 60 days. Consumption of OFO diet for 60 days reduced the diversity of volatile compounds, significantly reduced the content of total esters and increased the content of total aldehydes and total aromatics in grouper muscle. Furthermore, ingestion of OFO diet significantly reduced the mRNA expression of fraction growth factors and antioxidant genes in the muscle of grouper. In conclusion, the increasing MDA content in FO and the oxidative rancidity of PUFA can cause the deterioration of grouper quality and flavor due to oxidative muscle damage.
