Isolation and Characterization of Snakehead Fish Meal Extract with Fresh, Boiled, and Steamed Treatments and Its Potential for Health Drinks and Immunomodulators

Abstract

Albumin is one of the proteins that currently have an important role for the organism's body. This study aims to determine the characteristics of albumin with several treatments which will later be applied to cendol drinks. The treatments for extraction and albumin flour were fresh, boiled, and steamed, which were tested for extract yield, amino acids, and molecular identification using SDS-Page. The results showed that the steam treatment of the extract produced the highest yield of 0.42g/dL. The highest amino acid was in albumin flour with boiled treatment, namely each essential amino acid, namely leucine and non-essential amino acid, namely leucine. Identification of albumin molecular weight showed that albumin was found only in fresh and flour conditions when fresh. Other results indicate the possibility of processing factors affecting the presence of albumin which is easily soluble in water. albumin isolation from snakehead fish can potentially be developed into immunomodulatory health products
