ABSTRACT
Smoked fish is the result of the processing of fresh fish through the stages of weeding, washing, soaking in or without salt solution, draining, and smoking. This study aims to estimate the shelf life of smoked catfish coated with edible coating chitosan, red ginger, and red galangal essential oil. Estimation of shelf life using the acceleration method by storing the smoked catfish for 30 days at three different temperatures, i.e., 30, 35, and 40°C. The parameters observed during the storage were the color of smoked catfish, sensory assessments of rancidity, and thiobarbituric acid (TBA) value. The obtained data were analyzed using linear regression to show the relations between storage time and the measured variables. Furthermore, the Arrhenius method was used to calculate the shelf life of smoked catfish to compare the decline in the quality of smoked catfish. The result showed at a temperature of 30°C, the smoked catfish coated with edible coating chitosan and red ginger essential oil decreased the color value L, a*, and b* of each by 22.45, 5.22, and 4.55. The shelf life of smoked catfish based on the rancidity sensory test was 32.30 days with the regression equation y = -1415.1x + 1.8884. The smoked catfish coated with edible coating chitosan, red ginger, and red galangal essential oil decreased the color value L, a*, and b* of each by 23.81, 5.98, and 4.96. The shelf life of smoked catfish based on the rancidity sensory test was 36.27 days with the regression equation y = -1686.8x + 2.6692.
Keywords: Edible coating, red galangal, red ginger, shelf life, and smoked catfish
