| 摘要: |
| 为探究不同生境、不同食物源拟穴青蟹(Scylla paramamosain，以下简称“青蟹”)的螯足肌肉营养品质的差异，本研究通过采集5种不同生境青蟹(生态青蟹、藤壶青蟹、天然青蟹、混饵养殖青蟹和单饵养殖青蟹)，取其螯足肌肉组织测定基本营养成分、氨基酸含量和脂肪酸含量，并通过必需氨基酸指数(EAAI)、支链氨基酸与芳香族氨基酸含量的比值(F)进行分析。结果表明，生态青蟹的蛋白质含量略高于天然青蟹和混饵养殖青蟹；藤壶青蟹的含水率最高，蛋白质含量最低；5种青蟹的粗脂肪和总灰分含量差异均不显著。生态青蟹的总氨基酸含量和必需氨基酸含量均最高，藤壶青蟹的鲜味氨基酸含量最高；藤壶青蟹的EAAI (112.48)和F (2.36)最高，生态青蟹的EAAI (95.35)和F (1.95)分别与天然青蟹的EAAI (96.15)和F (1.90)基本一致；单饵养殖青蟹的EAAI (72.00)和F (1.53)均最低。生态青蟹的单不饱和脂肪酸、多不饱和脂肪酸含量最高，其二十二碳五烯酸+二十二碳六烯酸(EPA+DHA)显著高于天然青蟹，且部分不饱和脂肪酸含量显著高于天然青蟹、混饵养殖青蟹和单饵养殖青蟹。从蛋白质、总氨基酸、必需氨基酸和不饱和脂肪酸的含量来看，生态青蟹的含量最高；从EAAI和F来看，藤壶青蟹的评价最高，说明2种红树林生态修复产出的青蟹品质较好。 |

| Abstract: |
| To explore the differences in the nutritional quality of the claw foot muscles of Scylla paramamosain (hereinafter referred to as 'green crab’) from different habitats and food sources,five kinds of green crabs from different habitats (ecological green crab,barnacle green crab,natural green crab,mixed bait cultured green crab and single bait cultured green crab) were collected in this study.The basic nutrients,amino acid content and fatty acid content of the claw foot muscle tissue were measured,and the Essential Amino Acid Index (EAAI) and the ratio of branched chain amino acid to aromatic amino acid content (F) were analyzed.The results showed that the protein content of ecological green crab was slightly higher than that of natural green crab and mixed bait cultured green crab.The moisture content of the barnacle green crab was the highest and the protein content was the lowest.There was no significant difference in crude fat and total ash content among the five crabs.The total amino acid content and essential amino acid content of the ecological green crab were the highest,and the umami amino acid content of the barnacle green crab was the highest.The EAAI (112.48) and F (2.36) of barnacle green crab were the highest,and the EAAI (95.35) and F (1.95) of ecological green crab and EAAI (96.15) and F(1.90) of natural green crab were basically the same.The EAAI (72.00) and F (1.53) of single bait cultured green crab were the lowest.The content of monounsaturated fatty acids and polyunsaturated fatty acids in the ecological green crab was the highest,and its Eicosapntemacnioc Acid+Docosahexaenoic acid (EPA+DHA) was significantly higher than that of natural green crab,and the content of partial unsaturated fatty acids was significantly higher than that of natural green crab,mixed bait cultured green crab and single bait cultured green crab.According to the contents of protein,total amino acids,essential amino acids and unsaturated fatty acids,the content of ecological green crab is the highest.From the perspective of EAAI and F,the evaluation of barnacle green crab is the highest,indicating that the quality of the green crabs produced by the two mangrove ecological restorations is better. |
