Utilization Of Alcalase Enzyme In The Production Of Malong Fish Protein Hydrolysate (Congresox Talabon) As An Α-Glucosidase Enzyme Inhibitor
Main Article Content
Abstract
This study aims to determine the best protein hydrolyzate from the enzymatic hydrolysis process of malong fish (Congresox talbon) using different concentrations of the alcalase enzyme. The hydrolysis process was carried out at concentrations of 1.5, 2.0, and 2.5% (w/v protein) at 55oC, pH 7.5, and hydrolysis time of 2 hours. The parameters measured included the degree of hydrolysis, yield, protein analysis using the Lowry method, antioxidants, then protein hydrolyzate with the best concentration was analyzed for total amino acids, and α-glucosidase enzyme inhibitors. The results showed the use of alcalce enzymes with a concentration of 2.5% (w/v); temperature 55oC; pH 7.5; and hydrolysis time of 2 hours is the best treatment which has a yield value of 59.04%, the optimum degree of hydrolysis is 91.58% with an IC50 value of <50 ppm which is 43.95 ppm. The dominant amino acid content is glutamate and leucine, and is able to inhibit the action of the α-glucosidase enzyme at a concentration of 10000 ppm (1.04%).
