The present invention relates to a method for manufacturing slices of balloon flower roots, wherein sliced balloon flower roots, obtained by slicing balloon flower roots into a uniform thickness, are vacuum-dried, impregnated with sugar, coated, and dried. The method for manufacturing slices of balloon flower roots including the following steps: a) manufacturing sliced balloon flower roots by slicing balloon flower roots into a uniform thickness b) vacuum-drying the sliced balloon flower roots c) impregnating the sliced balloon flower roots, processed by step b), with sugar by immersing the sliced balloon flower roots in a sugar solution d) picking up the sliced balloon flower roots from the sugar solution, placing the sliced balloon flower roots, and removing a residual sugar solution excessively remaining on the sliced balloon flower roots e) coating the sliced balloon flower roots, processed by step d), with a powder-type food additive and f) drying the sliced balloon flower roots processed by step e). Therefore, according to the present invention, a large amount of the sliced balloon flower roots, which have taste, smell, and texture unique to balloon flower roots, include a large amount of effective ingredients, and have excellent flavor, can be manufactured within a relatively short period.COPYRIGHT KIPO 2016본 발명은 도라지를 일정한 두께로 슬라이싱한 편도라지를 진공건조한 다음 당침하고, 코팅 및 건조하는 것을 특징으로 하는 도라지 절편 제조방법에 관한 것으로, a) 도라지를 일정한 두께로 슬라이싱하여 편도라지를 제조하는 단계 b) 상기 편도라지를 진공건조하는 단계 c) 상기 b)단계를 거친 편도라지를 당침액에 침지하여 당침하는 단계 d) 상기 당침액에서 편도라지를 건져내고 정치시켜 편도라지에 과도하게 묻은 당침여액을 제거하는 단계 e) 상기 d)단계를 거친 편도라지를 분말형 식품첨가물로 코팅하는 단계 및 f) 상기 e)단계를 거친 편도라지를 건조하는 단계를 포함한다. 따라서 본 발명에 따르면 도라지 고유의 맛, 향 및 질감을 지니면서, 유용성분 함량이 높고 풍미가 우수한 도라지 절편을 비교적 짧은 기간 내에 대량으로 제조할 수 있다.
