中文摘要:
      分析凡纳滨对虾(Litopenaeus vannamei)在大棚养殖(40、60、74、94 d)和露天养殖(40、60、80、95 d)模式下相近生长阶段肌肉中水解氨基酸和脂肪酸的组成和含量,并对其营养价值进行评价。结果表明:(1)在大棚养殖和露天养殖模式下,凡纳滨对虾肌肉中粗蛋白、粗脂肪和粗灰分的含量在其相近生长阶段间无显著性差异。(2)大棚养殖模式下,凡纳滨对虾生长至40、60、74、94 d时的不饱和脂肪酸分别占脂肪酸总量的64.46%、60.97%、62.47%、63.16%;露天养殖模式下,凡纳滨对虾生长至40、60、80、95 d时的不饱和脂肪酸含量分别占脂肪酸总量的67.69%、64.74%、65.35%、65.63%。两种养殖模式下凡纳滨对虾肌肉均含丰富的不饱和脂肪酸,且大棚养殖模式下凡纳滨对虾在其相近生长阶段的多不饱和脂肪酸显著(P<0.05)低于露天养殖。(3)大棚养殖和露天养殖模式下相近生长阶段凡纳滨对虾肌肉氨基酸组成基本一致,均包含17种氨基酸。大棚养殖模式下,凡纳滨对虾生长至40、60、80、95 d时必需氨基酸占总氨基酸的比值分别为29.36%、30.71%、33.28%、32.91%,必需氨基酸与非必需氨基酸比值分别为50.04%、55.63%、63.14%、60.56%;露天养殖模式下,凡纳滨对虾生长至40、60、80、95 d时必需氨基酸占总氨基酸的比值分别为34.70%、33.69%、32.93%、34.11%,必需氨基酸与非必需氨基酸比值分别为64.44%、63.72%、62.66%、66.76%,基本符合FAO/WHO理想模式,露天养殖的凡纳滨对虾氨基酸总量、必需氨基酸总量、鲜味氨基酸总量均显著高于大棚养殖。大棚养殖和露天养殖模式下凡纳滨对虾是一种高蛋白低脂肪,具有较高营养保健价值的虾类资源;露天养殖凡纳滨对虾肌肉营养品质总体优于大棚养殖的凡纳滨对虾。
英文摘要:
      The composition and contents of hydrolytic amino acids and fatty acids of greenhouse cultured (40, 60, 74, 94 d) and outdoor cultured (40,60,80,95 d) Litopenaeus vannamei were analyzed during similar growth phases and the nutritional values were assessed. The results showed that:(1)Under the greenhouse culture and outdoor culture mode, the contents of crude protein, crude fat and ash in shrimp muscles showed no obvious difference among Litopenaeus vannamei in similar growth phases.(2)Under the greenhouse culture mode,the unsaturated fatty acids of Litopenaeus vannamei at 40, 60, 74 and 94 d accounted for 64.46%, 60.97%, 62.47% and 63.16% of the total fatty acid content, respectively.Under the outdoor culture mode, the unsaturated fatty acid contents of Litopenaeus vannamei at 40, 60, 80 and 95 d accounted for 67.69%, 64.74%, 65.35% and 65.63% of the total fatty acid content, respectively.The muscles of Litopenaeus vannamei were rich in unsaturated fatty acids under the two cultivation modes, and the polyunsaturated fatty acids of Litopenaeus vannamei in the similar growth stage under the greenhouse cultivation mode were significantly lower than that in the outdoor cultivation mode. (3)The amino acids composition in greenhouse cultured and outdoor cultured Litopenaeus vannamei in similar growth stages were consistent, which contained 17 kinds of amino acids.When Litopenaeus vannamei grew to 40 d, 60 d, 80 d and 95 d in the greenhouse culture mode,ΣEAA/ΣAA ratios were 29.36%, 30.71%, 33.28%, 32.91% and ΣEAA/ΣNEAA ratios were 50.04%, 55.63%, 63.14%, 60.56%.When Litopenaeus vannameigrew to 40 d, 60 d, 80 d and 95 d in the outdoor culture mode,ΣEAA/ΣAA ratios were 34.70%, 33.69%, 32.93%, 34.11%,ΣEAA/ΣNEAA ratios were 64.44%, 63.72%, 62.66%, 66.76%, which basically conformed to the FAO/WHO ideal model. The total amount of amino acids, essential amino acids and delicious amino acids in outdoor cultured Litopenaeus vannamei were higher than those cultured in greenhouse.Conclusions are as follows:Greenhouse cultured and outdoor cultured Litopenaeus vannamei was a kind of shrimp which had high protein, low fat and high nutritional value; The nutritional quality of muscles of outdoor cultured Litopenaeus vannamei was better than that of greenhouse cultured Litopenaeus vannamei.
