Summary

<span class="y2iqfc"><span lang="EN-US">Gelatin is a type of protein consisting of amino acids produced through the hydrolysis of collagen. One natural source that can be used as a raw material for making gelatin is the shrimp shell. This study aims to determine the characteristics of gelatin made from Jerbung shrimp shells (<em>Fenneropenaeus marguensis de Man</em>) using three types of acid solvents, namely, acetic acid, phosphoric acid, and sulfuric acid. The hydrolysis process by soaking with acid solvent was carried out with varying concentrations of 1%, 3% and 6%. The results of the analysis of the physical characteristics of gelatin with acetic acid, sulfuric acid and phosphoric acid were suitable for SNI. The pH values ranged from 4.5-6.5, the water content was less than 16%, the ash content was 3.25%, the viscosity ranged from 1.5-7 cP, and the gel strength ranged from 50-300 blooms. The FTIR data of gelatin synthesized from 3 types of acids revealed typical absorption peaks, such as N-H and O-H functional groups at wavenumbers of 3600-3400 cm^-1, C-H groups 3000-2840 cm^-1, and C=O groups at wavenumbers of 1800-1650 cm^-1. These results indicate that Jerbung shrimp shells have potential as alternative raw materials for making gelatin.</span></span>
