The present invention relates to a method for manufacturing a functional natural seasoning agent using fusiformis powder and a fusiformis powder-containing functional natural seasoning agent manufactured by the method including: (S1) a step of washing fusiformis, drying it, and then turning it into powder (S2) a step of mixing the fusiformis powder obtained in step (S1) with bamboo salt powder and roasted salt at a weight ratio of 1:2 to 3:1 to 2 and (S3) a step of binding the fusiformis powder, the bamboo salt powder, and the roasted salt by stirring the mixture of the fusiformis powder, the bamboo salt powder, and the roasted salt obtained in step (S2) with a stirring machine. The fusiformis powder-containing seasoning agent manufactured by the method according to the present invention that includes the steps described above is capable of maintaining native fusiformis ingredients as they are because the fusiformis is used after being turned into the powder as it is. In addition, its flavor and deep taste can be increased in spite of salt content reduction. Since the bamboo salt powder and the roasted salt are used after being mixed with each other, appropriate binding with the fusiformis powder can be ensured and the storability of the seasoning agent can be improved. Accordingly, the fusiformis powder-containing seasoning agent manufactured by the present invention is safer for the human body, less salty, more functional, more savory, and deeper in taste than existing synthetic seasoning agents. Accordingly, it is expected to be effectively used as a natural seasoning agent for well being.본 발명은 톳 분말을 이용한 기능성 천연 조미료의 제조방법 및 이에 따라 제조된 톳 분말 함유 기능성 천연 조미료에 관한 것으로, (S1) 톳을 세척한 다음 건조시켜 분말화하는 단계 (S2) 상기 단계 (S1)에서 분말화된 톳 분말과 죽염 가루 및 구운 소금을 1:2~3:1~2의 중량비로 혼합하는 단계 및 (S3) 상기 단계 (S2)에서 혼합된 톳 분말, 죽염 가루 및 구운 소금 혼합물을 교반기를 사용하여 교반하여 톳 분말과, 죽염 가루 및 구운 소금을 결착시키는 단계를 포함하는 본 발명에 따라 제조된 톳 분말 함유 조미료는 톳을 통째로 분말화하여 사용함으로써 톳의 고유성분을 그대로 유지시킬 수 있으며 소금의 함량을 줄이면서도 감칠맛과 깊은맛을 증대시키는 이점이 있다. 또한
