Abstract

The nutritional compositions, amino acids, fatty acids, inorganic salts and trace elements from four kinds of abalone muscle (Haliotis discus hannai, Haliotis diversicolor, Haliotis fulgens and hybrid abalone) were analyzed and the nutritional values were evaluated.The results showed that there was no significant difference in protein contents from 4 kinds of abalone muscle(p>0.05), which were between 18.92% and 21.63%; there was no significant difference in fat between 0.04% and 0.09%(p>0.05).The contents of total sugar were significant difference(p>0.05), with the highest level of 4.81% in hybrid abalone and the lowest level of 3.39% in Haliotis discus hannai.The amino acid composition was basically the same with 17 kinds of amino acids and the total contents were between 16.24 g/100g and 18.12 g/100g, including 8 kinds of essential amino acid in the range of 4.78 g/100g to 5.08 g/100g.The ratios of flavor amino acid and total amino acid (UAA/TAA) were in the range of 43.35% to 43.97%.Collagen protein contents were between 17.60% to 17.96%, except abalone muscle from Haliotis diversicolor (9.27%).According to the amino acid score (AAS) and chemical score (CS) data analysis, the nutrition value of hybrid abalone is highest among 4 kinds of abalone.Four kinds of abalone are rich in palmitic acid, EPA and elements like K, Ca, Zn and so on.Therefore, abalone is a high-value seafood with high protein, low fat and high nutritional value.
