Abstract: Nutritional components of the salted fish from southeast of Guizhou were analyzed and evaluated,including general nutrients,minerals and trace elements,amino acid compositions,fatty acid compositions,nitrite and heavy metals content.The results showed that the salted fish contains rich minerals and trace elements,and there were 16 kinds of amino acids in this salted fish.The ratios of essential amino acids(EAA) in total amino acids(TAA) was 46.09% and the EAA/NEAA was 85.50%,respectively.The fatty acids in the salted fish are mostly made up of unsaturated ones,and the ratio between the polyunsatu-rated and saturated ones is 5.99.In addition,the nitrite level is very low and the heavy metals such as As,Pb,Hg and Cd could not be detected in the salted fish.All results suggested that the salted fish from southeast of Guizhou is a kind of high-quality and safe food with particular flavors and high nutritional values.
