| Summary: | Eggs are a source of animal protein needed by the body and contain complete essential amino acids. Chicken eggs are easily damaged or changed so the quality of the eggs decreases with the length of storage. This damage can be prevented by coating. Past studies concluded that edible coating can maintain the quality of chicken eggs. The purpose of this study was to determine the effect of coating chicken eggs using chitosan and casein edible coating with the addition of garlic essential oil. The materials used are fresh chicken eggs, edible coating solution and garlic essential oil. The method used in this study was a laboratory experiment with Completely Randomized Nested Design with 2 treatments and 3 replications. Edible coating with the addition of garlic essential oil is expected to improve egg quality with a long shelf life. The result showed that chicken eggs coated with chitosan casein edible coating with the addition of garlic essential oil 1% for storage time of 0 days, 7 days, 14 days, 21 days and 28 days gave a very significant effect (P<0,01) on egg yolk pH, egg albumen pH, haugh unit and egg yolk index.
