      摘要:为探索金边鲤的最佳养殖模式和肌肉品质的基础数据资料,本研究测定稻田和池塘养殖模式下金边鲤和建鲤肌肉营养成分、理化特性和质构特性,并进行营养价值评价,为金边鲤稻田和池塘养殖的营养价值研究提供数据依据。结果表明:稻田金边鲤的粗脂肪、粗灰分和系水力均显著高于池塘金边鲤(P<0.05),而水分含量相反,同时,建鲤的各指标的差异不大。稻田金边鲤的肉质硬度、粘性、弹性、咀嚼性和回复性均明显高于在池塘养殖金边鲤,其中,硬度和回复性达到极显著水平(P<0.001),除了粘性和内聚性外,金边鲤肉质的硬度和弹性在两种养殖条件下均高于建鲤。稻田金边鲤7种必须氨基酸总量(?EAA)均为最高,除Thr和Lys外,稻田金边鲤的其他氨基酸含量均介于WHO/FAO和鸡蛋蛋白标准之间,必须氨基酸总量(?EAA)与氨基酸总量(?TAA)比值都在40%左右,氨基酸评分均在1.0左右,氨基酸指数均在100分以上,均高于建鲤。鉴定出的24种脂肪酸中,稻田养殖模式的金边鲤的饱和脂肪酸总量(?SFA)、不饱和脂肪酸总量(?MUFA)和DHA+LA+C18:1n9c(油酸)总量均高于其他各组,同时∑PUFA n-3/∑PUFA n-6高于0.2。本试验数据表明了稻田养殖模式的金边鲤具有较好的理化品质和质构特性,池塘养殖模式表现相对较差;相同养殖模式下,金边鲤肉质比建鲤肉质较有优势。综上所述,稻田养殖模式的金边鲤肉质价值较高,具有较高的产业开发潜力,稻田养殖模式是较优良的养殖模式。
英文摘要:
      In order to obtain the basic data of the best culture conditions and muscle quality of Jinbian carp, the nutrients of the muscles of Jinbian carp and Jian(Cyprinus carpio.V.jian) under the two culture modes of pond and paddy fields were determined and further analyzed by texture analyzer. And determine the muscle quality of the sample. The results show: The crude fat, crude ash and waterpower of Jinbian carp paddy were significantly higher than those in the pond (P<0.05), while the water content was opposite. At the same time, the difference in Jian carp was not significant. The meat hardness, gumminess, springiness, chewiness and resilience of Jinbian carp in paddy were significantly higher than those in the pond. And the hardness and resilience were extremely significant (P<0.001). In addition to gumminess and cohesiveness, the hardness and springiness of Jinbian carp meat are higher than that of Jian carp under both culture conditions. The 7 essential amino acids in Jinbian carp of paddy are the highest. Except for Thr and Lys, the other amino acids in paddy are between the WHO/FAO standard and the egg protein standard. The EAA/TAA (%) is About 40%, the amino acid scores are all around 1.0, and the EAAI is above 100 points, which is higher than Jian. Among the 35 fatty acids identified, the ∑SFA,∑MUFA and the total amount of DHA+LA+oleic acid in the paddy field culture model were higher than those of other groups, and PUFA n-3/∑PUFA n -6 is much higher than 0.2.The experimental data indicated that the paddy field culture model had good physical and chemical quality and texture characteristics, and the pond culture mode was relatively poor. Under the same cultivation mode, Jinbian carp had obvious advantages over Jian carp. In summary, the paddy field culture model has a higher meat quality value and higher industrial development potential, and the paddy field culture mode is a better breeding mode.
