ABSTRACT
Smoked catfish can be damaged due to the oxidation process which causes rancid flavor during storage. Therefore, applying an edible coating with the addition of red galangal essential oil is necessary. Red galangal contain antioxidant compounds that can be added into edible coating. The purpose of this research was to estimate the shelf life of smoked catfish coated with chitosan edible coating and red galangal essential oil packed with aluminum foil using the acceleration method. The estimation of smoked catfish shelf life using the acceleration method was carried out by storing the smoked catfish at temperatures of 35, 45, and 55ºC for 30 days. Analysis of smoked catfish color, rancidity sensory scores, and TBA values obtained were analyzed using linear regression. The regression results of sensory scores for rancidity and TBA values were continued for calculating the shelf life of smoked catfish using the accelerated method. Data were analyzed using linear regression and the equations obtained were used to calculate the shelf life of smoked catfish at normal temperature (30ºC). The color values of L*, a*, and b* without the addition of red galangal essential oil decreased faster and the shelf life was shorter than the addition of 1% red galangal essential oil. The shelf life of smoked catfish without the addition of red galangal essential oil at 30ºC was 29.63 days. The shelf life of smoked catfish with the addition of 1% red galangal essential oil at 30°C was 38.52 days. The results of this study indicated that the smoked catfish treated with the addition of 1% red galangal essential oil was able to retain the smoked catfish’s color and the smoked catfish had a longer shelf life than the treatment without the addition of red galangal essential oil.
