Some biological components in natural marbled eel in Thua Thien Hue, Vietnam

Abstract

A species of catfish belonging to the Anguilla genus called Anguilla marmorata has long been exploited and grown in Vietnam. Marbled eels are regarded as a specialty seafood species with several therapeutic and nutritive benefits. This study used High-Performance Liquid Chromatography (HPLC) to identify various biochemical and nutritional ingredients in A. marmorata collected in its natural habitat. There was 16 different amino acids analysed in the muscle, skin, and mucus of marbled eels at the rates of 14.01%, 5.48%, and 9.96%, respectively. Twenty-four fatty acids were found in muscle and skin, while only nine fatty acids were detected in the mucus with proportions of 11.93, 25.91, and 0.37 g/100 g, respectively. Six different vitamins (A, B3, B5, D3, C, E) are found in the muscle of the eel; five types of vitamins (A, B3, B5, D3, E) were detected in the skin; and three vitamins (B3, B5, C) are found in mucus. Using HPLC analysis has shown remarkable effectiveness in micronutrient analysis in nutritional research. The results will increase our knowledge of the nutritive benefits of the A. marmorata and point the way toward the creation of functional foods and cosmetics with natural ingredients that may be used on people.
