Nutritional Quality Evaluation for Cheliped Muscle of Scylla paramamosain in Different Habitats
摘要
Abstract
To explore the differences in the nutritional quality of the claw foot muscles of Scylla paramamo-sain(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 cul-tured 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 ana-lyzed.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 ecolog-ical green crab were the highest,and the umami amino acid content of the barnacle green crab was the high-est.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 natu-ral 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.关键词
