A comparative study of two types of third-generation Chinese soft-shelled turtles (Trionyx sinensis) from the Yangtze River (i.e., Type A with black spots on the carapace and Type B without spots) was conducted to evaluate the effect of selective breeding on their nutritional composition. Our nutrient analysis results indicated that both types were high-quality aquatic products with high protein and low fat contents. The amino acid contents in the muscle of type A were significantly higher than those of type B (P < 0.05), but no significant differences were observed in the calipash. Additionally, the amino acid score (AAS) in the muscle of type A was >1, which was significantly higher than that of type B (P<0.05). The contents of all fatty acids and EPA+DHA were significantly higher in Type A than in type B (P<0.05), whereas there were no significant differences in the fatty acid composition of the calipash of the two types (P > 0.05). The muscle atherogenicity index (AI) and thrombogenicity index (TI) of the two types were 0.42-0.45 and 0.33-0.34, respectively, which were significantly lower than that of the calipash (P<0.05). The hypocholesterolemic/hypercholesterolemic fatty acid ratio (HH) was 3.91-3.89, which was significantly higher than that of the calipash (P<0.05). Additionally, the collagen content of type A calipash was significantly higher than that of type B (P<0.05). Collectively, our findings indicated that selective breeding could improve the nutritional value of T. sinensis from the Yangtze River. [ABSTRACT FROM AUTHOR] |
