Abstract:

In this study, the nutrient components in dried Engraulis japonicus from the sea areas near Zhejiang, Xiamen and Hainan were analyzed and evaluated. The results showed that protein contents in dried Engraulis japonicus from Zhejiang, Xiamen and Hainan coastal areas were 45.25%, 42.42% and 38.95%, and fat contents were 4.71%, 3.42% and 3.05%, respectively. Dried Engraulis japonicus from the three sea areas exhibited a proportional balance in total content of amino acids in the range of 34.4% to 38.7%. All essential amino acids essential for human body were contained in dried Engraulis japonicus from the three sea areas, and methionine acted the first limited amino acid, and lysine content was up to 3.86 g/100 g and flavor amino acids represented 48.23% of the total amount of amino acids. Dried Engraulis japonicus was low in fat but rich in polyunsaturated fatty acids, especially DHA, of which the content was between 21.21% and 25.83%, and Ca, P, Fe, Zn, Se and other trace elements. The detection and analysis of heavy metal elements and other toxic substances in dried Engraulis japonicus indicated that all the dried products from these three coastal areas met national safety and health standards. Therefore, dried Engraulis japonicus is a kind of marine product with good quality and high nutritional value.
