[Objectives]The quality of Scylla paramammosain produced in Fujian,Sanmen and Shanghai were analyzed and evaluated.[Methods]Adult Scylla paramammosain from Fujian,Sanmen and Shanghai were separated for their muscles and gonads,which were analyzed for nutritional components.[Results]The muscle moisture content of S.paramammosain from Sanmen was significantly higher than those in S.paramammosain from Fujian and Shanghai.The muscle protein contents of S.paramammosain from the three regions ranked as Shanghai>Fujian>Sanmen(P<0.05).The muscles of S.paramammosain from Shanghai had the highest crude fat and crude ash contents.The moisture contents of the gonads of the S.paramammosain from the three regions had no significant differences.The protein contents of the gonads of S.paramammosain from the three regions ranked as Shanghai>Sanmen>Fujian(P<0.05).The S.paramammosain from Sanmen had the highest crude fat and crude ash contents in gonads.The contents of 17 amino acids detected in the muscles and gonads of S.paramammosain from the three different regions were different.The total amounts of total amino acids(TAA),essential amino acids(EAA)and flavor amino acids(FAA)in the muscles of S.paramammosain from Sanmen were significantly lower than those produced in Fujian and Shanghai(P<0.05),but the proportions of essential amino acids(EAA)and flavor amino acids were not significantly different.The proportion of EAA and FAA in the gonads of S.paramammosain produced in the three areas were significantly different(P<0.05).There were also differences in the fatty acid composition of the muscles and gonads of S.paramammosain from the three different regions.The proportion of EPA in the muscles of S.paramammosain from Fujian was higher than those of other two groups,but the differences were not significant;the proportion of DHA was significantly higher than those of other two groups,and the differences were significant(P<0.05);and the proportions of n3 PUFA in muscles of S.paramammosain produced in Fujian and Sanmen were signific 展开更多

为了评价不同饲料来源对拟穴青蟹营养品质的影响,取体重(8.52±0.34) g的蟹,分成两组,分别饲喂配合饲料和冰鲜鱼,试验周期42 d试验结束后分别取配合饲料(配合饲料组)和冰鲜鱼(冰鲜鱼组)养殖的拟穴青蟹,分离其肌肉和性腺,测定了肌肉... 为了评价不同饲料来源对拟穴青蟹营养品质的影响,取体重(8.52±0.34) g的蟹,分成两组,分别饲喂配合饲料和冰鲜鱼,试验周期42 d试验结束后分别取配合饲料(配合饲料组)和冰鲜鱼(冰鲜鱼组)养殖的拟穴青蟹,分离其肌肉和性腺,测定了肌肉和性腺的水分、蛋白质、脂肪、灰分、氨基酸等的含量及脂肪酸的组成。结果表明:配合饲料组拟穴青蟹肌肉水分含量显著低于冰鲜鱼组(P<0.05),粗蛋白和粗灰分含量显著高于冰鲜鱼组(P<0.05);冰鲜鱼组拟穴青蟹性腺水分含量显著低于配合饲料组(P<0.05),粗脂肪和粗蛋白、粗灰分含量显著高于配合饲料组(P<0.05)。配合饲料组拟穴青蟹肌肉中总氨基酸(TAA)、必需氨基酸(EAA)和呈味氨基酸(FAA)总量均显著高于冰鲜组(P<0.05)。配合饲料组肌肉异亮氨酸和缬氨酸的氨基酸评分(AAS)高于冰鲜鱼组,赖氨酸低于冰鲜鱼组;异亮氨酸化学评分(CS)高于冰鲜鱼组,苯丙氨酸+酪氨酸、赖氨酸评分低于冰鲜鱼组;必需氨基酸指数(EAAI)高于冰鲜鱼组。配合饲料组性腺异亮氨酸、亮氨酸、苏氨酸、苯丙氨酸+酪氨酸AAS评分低于冰鲜鱼组,赖氨酸、缬氨酸和蛋氨酸+胱氨酸高于冰鲜鱼组;异亮氨酸、亮氨酸、苯丙氨酸+酪氨酸CS评分低于冰鲜鱼组,赖氨酸、缬氨酸和蛋氨酸+胱氨酸高于冰鲜鱼组;EAAI指数高于冰鲜鱼组。配合饲料组拟穴青蟹肌肉DHA、EPA、n6-PUFA及n3-PUFA比例均显著高于冰鲜鱼组(P<0.05),性腺中DHA显著高于冰鲜鱼组、EPA显著低于冰鲜鱼组(P<0.05)。综上所述,配合饲料饲喂的拟穴青蟹肌肉和性腺的EAAI指数高,其蛋白质品质较高,说明饲料组成对拟穴青蟹的品质影响显著,可通过调整饲料配方提高拟穴青蟹的品质。 展开更多
