Fish is a food that is very susceptible to degradation. One way to maintain the freshness of the fish is by using packaging edible coating with natural ingredients. This study used that chitosan and chienese lemon extract (Citrus mitis) as the natural agent in edible coating production. The purpose of this study was to examine the application of edible coating made from chitosan and citrus mitis on tuna fillets and to test the application of edible coating at each concentration, to get the best concentration based on pH and Total Bacterial Count (TBC). Tuna fillet with a size of 3 x 5 cm with a thickness of 1 cm was made edible coating by immersion system. Furthermore, edible coating made from chitosan in the concentrations of 1–4% was made by acetic acid solvent of 1% at a temperature of 50°C for 60 min, followed by the addition of 0.5% glycerol. On the other hand, edible coating made from citrus mitis in the concentration of 10-40% was made by jelly solution of 1% at 50°C for 60 min, followed by adding 0.5% of glycerol. Based on this study, it was understood that the best concentration for edible coating made from chitosan and citrus mitis was respectively 1% (pH 5.67; TBC 4.93) and 40% (pH 5.32; TBC 6.23). Furthermore it was known that the higher acid concentration, the better edible coating was obtained.
