In order to evaluate the nutritional value and provide the basis data for the development of marine functional food,the general nutrients,fatty acids,amino acids,cholesterol,taurine,vitamins and inorganic elements inNotarchus leachii freeri eggs were analyzed.The results showed that the contents of moisture,crude protein,crude fat and ash inNotarchus leachii freeri eggs were 90.73%、2.53%、0.62% and 1.76%,respectively.Twenty-four kinds of fatty acids were detected.The contents of the unsaturated fatty acids were rich,accounting for 57.51% of the total fatty acids content,and the total amount of EPA and DHA accounted for 27.28%.Seventeen amino acids were found inNotarchus leachii freeri eggs.The contents of the essential amino acids (EAA) and delicious aminoacids (DAA) were 7.41 g/100 g and 6.86 g/100 g,respectively,accounting for 34.76% and 32.18% of the total amino acids (TAA).The EAA composition basically met the FAO/WHO criteria.According to nutritional evaluation in amino acid score (AAS) and chemical score (CS),the first limiting amino acid ofNotarchus leachii freeri eggs was methionine.The contents of cholesterol and taurine were 19.8 mg/100 g and 180 mg/100 g,respectively,inNotarchus leachii freeri eggs,and the ratio of taurine to cholesterol (T/C) was 9.09.Their vitamins VD、VE and VB2contents were 47 μg/100 g,42.2 mg/100 g and 0.02 mg/100 g,respectively.The macroelements (Ca,Mg,K and Na) and trace elements (Fe,Zn,Mn and Se,etc.) were abundant inNotarchus leachii freeri eggs.In summary,Notarchus leachii freeri eggs are rich in various nutrient elements with a balanced proportion,and are high-quality seafoods that meet the nutritional needs of human body.
