Nutritional Analysis and Evaluation on Eggs of Hemitripterus villosus
摘要
Abstract
In this experiment, common nutritional components and the composition of amino acids and fatty acids of eggs of Hemitripterus villosus were determined by routine methods to evaluate the nutritive quality of eggs of Hemitripterus villosus. The results showed as follows: the content of crude protein in eggs of Hemi-tripterus villosus was 17. 26% (fresh weight basis), and the contents of total amino acid (TAA), essential a-mino acids (EAA) and nonessential amino acids (NEAA) were 78. 77%, 33. 24% and 38. 95% (dry weight basis), respectively. The ratio of EAA to TAA (EAA/TAA) was 0. 42 and the ratio of EAA to NEAA (EAA/NEAA) was 0. 85. Amino acid score (AAS) and chemical score (CS) for the first limiting amino acid (methionine+cysteine) were 0. 82 and 0. 47, respectively. Essential amino acid index (EAAI) of eggs of Hemitripterus villosus was 75 . 19 . The content of crude fat in eggs of Hemitripterus villosus was 2 . 83%( fresh basis weight) , and the contents of saturated fatty acids ( SFA) , monounsatarated fatty acids ( MUFA) and polyunsaturated fatty acids ( PUFA) accounted for 24. 73%, 23. 86% and 50. 29% of total fatty acids, respectively. Moreover, the content of eicosapntemacnioc acid ( EPA ) + docosahexaenoic acid ( DHA ) in eggs of Hemitripterus villosus was as high as 40 . 59% with EPA/DHA at 0 . 68 . It is concluded that the eggs of Hemitripterus villosus have high nutritional value, which are suitable to produce caviar.关键词
