- Abstract
To evaluate comprehensively the nutritional value of the muscle from pond-reared Procambarus clarkia, Procambarus clarkia reared in paddy field, and wild Procambarus clarkia, the compositions and contents of their muscles were determined. The results showed that the crude protein content of muscle decreased in this order: paddy field group (84.42%)>pond group (83.59%)>wild group (82.81%) (p>0.05). The crude fat content of the muscle was in this order: paddy field group (2.96%)> pond group (2.22%)>wild group (1.48%) (p<0.05). The values of TAA, ΣEAA, ΣEAA/ΣTAA, ΣEAA/ΣNEAA and ΣDAA/ΣTAA groups followed this order: pond group> rice field group> wild group (p>0.05). According to AAS, the first limiting amino acids of the pond-reared, paddy field-rear and wild Procambarus clarkii were Thr, Val and Val, respectively. The second limiting amino acids were all Met+Cys. According to CS, the first limiting amino acids were all Met+Cys, and the second limiting amino acids were Val, Thr and Val, respectively. There were 13, 14 and 15 kinds of fatty acids detected in the muscle of the pond-reared, paddy field-rear and wild Procambarus clarkii, of which ΣSFA was 48.06%, 44.03% and 39.95%, respectively(p<0.05); ΣMUFA was 35.48%, 31.03% and25.76%, respectively(p< 0.05); ΣPUFA was 16.46%, 24.93% and32.30%, respectively(p< 0.05). The n-3/n-6 ratios were in this descending order: wild group (0.18)<paddy field group (0.24)< pond group (0.35) (p<0.05).In summary, the overall nutritional value of the Procambarus clarkia muscle from either farming group (the paddy field group or pond group) was higher than that of the wild group.
