Abstract

The high intensity of use of cork fish (snakehead fish) to produce various products of fish albumin has put the natural stock of this fish species under a great pressure. Therefore, it is necessary to find alternative sources of fish albumin other than the cork fish. The purpose of this study was to analyze the albumin contents in two species of marine fish of low economic value. The fish used were red fusilier (Caesio chrysosonus) and Japanese threadfin bream (Nemipterus japonicus). The soluble protein and albumin were extracted by homogenizing100 g of fish meat in distilled water (1:4 w/v). The mixture was heated in a shaking water bath at 50ºC for 1 h and then filtered with a Whatman no. 40 filter paper. The total protein content of meat and filtrate was analyzed following the Kjeldahl method while the albumin content in the filtrate was measured according to the Lowry method. The results showed that the total protein content of C. chrysosonus and N. japonicus was 22.13% and 22.27%, respectively, whereas that of the filtrate was 25.77% and 28.36%, respectively. The albumin content in the C. chrysosonus was very low (1.08% of meat, w/w) while N. japonicas contained a moderate level of albumin (2.32% of meat, w/w). The Japanese threadfin bream is a potential source of fish albumin.
