Nutrition Components Analysis and Evaluation on Four Wild Populations of Peanut Worm Sipunculus nudus
摘要
Abstract
In this study,the main nutrition components of four wild populations of Peanut Worm Sipunculus nudus from (Donghai Island,Beihai, Zhangzhou,Suixi) were tested and analyzed in order to find differences among four wild populations. The results showed that the average mass fraction of moisture ofS. nudus from four wild populations was (79.39 ± 1.81)%;the average mass fraction of crude protein, crude fat and ash ofS. nudus from them were(80.54 ± 3.11)%,(1.45 ± 0.27)% and (9.75 ± 2.14)%,respectively. Except Tryptophan and Cystine, 16 common amino acids were detected fromS. nudus, which included 7 essential amino acids. And the average total mass fraction of amino acids was(63.91 ± 1.78)%;the average mass fraction of essential amino acids was(21.76 ± 0.63)%;the average mass fraction of delicious amino acids was(32.23 ± 0.64)%. There were four kinds of amino acids which are delicious amino acids among the highest mass fraction of five kinds of amino acids. And Glutamic was the highest mass fraction, which was (9.51 ± 0.26)%, Aspartic following, was (6.58 ± 0.22)%. The first limited amino acid and the second limited amino acid ofS. nudus from four wild populations were Valine and methionine,respectively. There were statistically significant differences in moisture,crude protein,crude fat, ash, total amino acids(TAA)and flavor amino acid mass fraction (DAA) from four wild populations (P<0.05). But there were not statistically significant differences in essential amino acids(EAA),EAA / TAA,DAA / TAA,non-essential amino acids (NEAA)and EAA / NEAA from four wild populations(P> 0.05)It was indicated that S. nudus is the marine food product of a high qualitywith good edible value and nutritive value.关键词
