Amino Acids Profiles and Chemical Properties of Four Inferior Sea Fishes in Madura, Indonesia

Abstract

This study was intended to identify chemical properties and contents of amino acids of four inferior sea fishes in Madura, Indonesia. The studied fishes were ‘bibisan’ (Apogon albimaculosus), ‘baji-baji’ (Platycephalidae cymbacephalus), ‘lidah’ (Cynoglossus lingua) and ‘sebelah’ (Psettodes erumei),The contents of the nutritive substances in the fish products (proteins, ash, and fats) were determined. This study confirmed that in terms of both quantity and quality of the fishes as a significant source of essential amino acids and lysine present in fishes could supplement the corresponding deficiency in plant proteins. The most abundant amino acids in all the fishes were glutamic acid that roles as flavor-enhancing compounds which provide an ‘umami’ (savory) taste in food.
