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.본 발명은 역삼투압 방식으로 가공된 사과를 포함한 기능성 과일류 및 제조방법에 관한 것으로서, 더욱 상세히 설명하면 약용성분, 식용성분, 향기성분, 색소성분 등으로 이루어진 침투물질을 선택하여 물이나 식용용매에 용해시킨 후, 압력 탱크 내부에 넣은 사과를 포함한 과일류에 스프레이로 분무한 후, 외부 압력인 압축공기를 압축탱크 내부로 공급 및 배출하여 상승 및 하강을 반복하는 압력 사이클로 이루어진 역삼투압방식으로 용질인 침투물질을 조직 내부로 침투시켜 사과를 포함한 과일의 고유성분과 침투물질의 기능성 성분이 다량 함유되도록 하는 것을 특징으로 한다.
