The present invention provides a manufacturing apparatus of direct heating type liquid aroma, which is liquid aroma that a reaction product produced by reacting liquid reactants at a heat supplier in which the surface temperature is maintained at 150-400°;C is condensed, and similarly reproduces the scent produced in the process of heating and cooking food whereas the content of harmful components such as benzopyrene is low, and a manufacturing method thereof. According to the present invention, a processed product, health functional food or medicine additionally having intrinsic aroma produced in the heating and cooking process of food without harmful elements to health are able to be manufactured. 본 발명은 액상의 반응재료가 표면온도가 150 내지 400 ℃로 유지되는 열 공급기에서 반응하여 생성된 반응생성물을 응축한 액상 향으로서, 식품의 가열조리 과정에서 생성되는 향을 유사하게 재현하면서, 벤조피렌 등의 위해성분 함량이 낮은 직접가열식 액상 향의 제조장치 및 제조방법을 제공함으로써, 건강 위해요소가 없이 식품 고유의 가열조리 과정에서 생성된 향이 부가된 가공식품, 건강기능식품 또는 의약을 제조할 수 있게 한다.
