Extraction of Dissolved Protein of Channa striata from Tarakan, North Borneo as a Source of Fish Serum Albumin

Extraction of dissolved protein of Channa Striata from Tarakan, North Borneo, as a source of fish serum albumin has been done. Albumin is a water-soluble protein and it is applied in various fields, including health, industry, and technology. The many benefits of albumin make albumin very important. However, albumin is a protein found in the body of living things, so it is necessary to perform the separation process. One of the living things that contain relatively high albumin is snakehead fish (Channa striata). The dissolved protein was extracted from snakehead fish meat using water as a solvent at a temperature of 50 °C. The protein obtained was characterized using proximate analysis and Fourier Transform Infra Red (FTIR) Spectrophotometer. The proximate analysis showed that the water, the fat, and the protein content were 8.67%, 3%, and 64.18%, respectively. The FTIR spectrum showed an amide group at 1600-1700 cm^-1 which is important in the albumin functional group. This study shows that snakehead fish in Tarakan, North Kalimantan has the potential as a source of fish serum albumin.
