The present invention relates to an edible coating agent for an apple comprising a wax solution, essential oil and an emulsifier. The present invention manufactures the edible coating agent for an apple by adding the essential oil to the wax solution and dispersing the essential oil in particles of nanosize; keeps freshness by delaying the aging of an apple by the edible coating agent; is able to prevent the decomposition of the apple due to microbes by the antibiosis of the essential oil; enables a consumer to safely consume the coating composition by securing microbiological stability; is economical since efficiency is increased even with a small quantity by dispersing the essential oil in particles of nanosize; and is able to reduce the loss of apples during storage and distribution since the quality of a product is maintained for a long time by increasing emulsion stability, thereby capable of being usefully applied as the edible coating agent for an apple and a manufacturing method for the edible coating agent for an apple.
