PURPOSE: A manufacturing method of a functional fruit is provided to infiltrate a functional ingredient into the insides of the tissues without damaging the shape of the fruit. CONSTITUTION: A manufacturing method of a functional fruit comprises the following steps. Insert a fruit(5) in a pressure tank(4), and seal it. Melt an osmotic agent in water or an edible solvent, and spray it inside of the tank. Supply the compressed air into the tank or eject the compressed air to the outside repetitively. Infiltrate the solute into the fruit in case the pressure provided from the outside rises, restore the pressure inside the tank to atmospheric pressure in case the pressure provided from the outside declines, and repeat the pressure cycle. Harmless air having an antioxidant ingredient substitutes for the compressed air is provided to the tank internally and repeat the pressure cycle. The external pressure supplied to the tank inside is 0-5atm. The osmotic agent is a medical ingredient, an edible ingredient, an aromatic ingredient, and a pigment ingredient. The fruit is an apple. In order to preserve the fruit comprising the infiltrated osmotic agent for a long term, keep it under a condition at reverse osmotic pressure. Vary the external pressure value depending on the thickness of the peel of the fruit.
