Smoked catfish is a method of fish processing involving smoking to reduce water content and enhance flavor. This study aims to estimate the shelf life of smoked catfish coated with chitosan edible coating infused with red galangal essential oil using an accelerated method. Acceleration method was conducted using the Arrhenius approach, where smoked catfish was stored for 30 days at three different temperatures: 30, 35, and 40°C. This studyused two treatments with three replications, namelytreatment ML0 (edible coating chitosan 3.5% with the addition of red galangal essential oil 1.2%) and ML1 (edible coating chitosan 3.5% with the addition of red galangal essential oil 1.2%). Parameters observed during storage included water content, fat content, sensory evaluation of rancidity, thiobarbituric acid (TBA) value, and color of smoked catfish. Based on the TBA value, the estimated shelf life of smoked catfish using the acceleration method in treatment ML0 had a regression equation for the rate of qualitydecline y= -972.83x + 0.4421, with a shelf life at 26°C for 33 days and 30°C for 31 days. Treatment ML1 had a regression equation for the rate of quality decline y = -1275.1x + 0.5998, with a shelf life at 26°C for 39 days and 30°C for 37 days. During the 30-day storage period, smoked catfish treated with ML0 experienced a decrease in color values L, a, and b, an increase in moisture content of 11.7876-13.0394%, and a decrease in fat content of 33.9425-32.7502%. Meanwhile, smoked catfish treated with ML1 during the same storage period showed a decrease in color values L, a, and b, an increase in moisture content of 10.4317-12.1746%, and a decrease in fat content of 33.3606-31.6489%. Smoked catfish treated with ML1 had a longer shelf life of 6 days compared to smoked catfish treated with ML0.
