摘　　要：为探究稻鳖生态种养对黄沙鳖肌肉品质的影响,对比分析了稻鳖生态种养与池塘养殖下养殖水质及黄沙鳖肌肉的营养成分、呈鲜味成分、有机酸组成、组织微观结构和食用后感官评价的差异。结果显示,稻鳖生态种养试验组养殖水质更优,稻鳖生态种养试验组黄沙鳖肌肉蛋白质含量显著提高,提高了90.81%,脂肪含量则显著低,降低了27.38%;稻鳖生态种养试验组黄沙鳖肌肉纤维面积高,而肌肉纤维密度低,肌肉口感更优;稻鳖生态种养试验组风味氨基酸含量占总氨基酸含量的75.17%,显著高于池塘养殖试验组(68.81%)(P<0.05);有机酸含量表现为,稻鳖生态种养试验组黄沙鳖肌肉的6种有机酸均低于池塘养殖试验组;稻鳖生态种养试验组黄沙鳖肌肉鲜味、余味、甜度显著高于池塘养殖试验组(P<0.05),分别提高55.6%,53.15%和832.35%,且土腥味更少。指出,稻鳖生态种养可提高黄沙鳖的肌肉品质,其产品质量更优,后期可在鳖类养殖中进行推广。In order to explore the effect of turtle-rice co-culture system on the muscle quality of Trionyx Sinensis, the differences in the nutritional composition, organic acid composition, tissue microstructure and sensory evaluation of the water quality in turtle-rice co-culture system and pond culture were analyzed. The results showed that the water quality of turtle-rice co-culture system was better, the turtle-rice co-culture system could improve water quality(P<0.05), protein and fat contents of turtle-rice co-culture system were significantly higher90.81% and lower 27.38% than those of pond culture, respectively. In turtle-rice co-culture system the muscle fiber area was higher 51.84% but the muscle fiber density was lower 17.14% than in pond culture. Meanwhile,the flavor amino acids which contains Gly, Asp, Thr, Glu, Ala and Pro in turtle-rice co-culture system accounted for 75.17% of the total amino acids, which was significantly higher than pond culture(68.81%)(P<0.05). More over, the contents of acetic acid(AA), malic acid(MA), oxalic acid(OA), succinic acid(SA), total organic acid,adenosine monophosphate(AMP), inosine(IMP) were significantly lower than those of pond culture(P<0.05), how ever, the formic acid(FA) and citric acid(CA) were not detected. Under sensory evaluation, the turtle-rice co-culture system fish had enhanced umami, sweetness, and overall flavor, and less of an earthy-musty taste compared to pond culture(P<0.05). It could be concluded that the fish-rice co-culture system could improve the muscle taste and quality of T. sinensis by improving the water quality and providing abundant natural biological food,supporting the view that the fish-rice co-culture system has superior performance.
