PURPOSE: A method for manufacturing an eco-friendly deodorizer containing a microbial fermentation is provided to minimize environmental pollution. CONSTITUTION: A method for manufacturing an eco-friendly deodorizer comprises: a step of mixing yogurt, dry yeast, sugar, and cheonggukjang(fermented soybeans), and adding warm water at 35-45 deg. C to prepare a raw material(S11); a step of fermenting the raw material at 35-45 deg. C for 7-10 days(S12); and a step of adding cold water(S13). [Reference numerals] (S11) Step of preparing a raw material by mixing yogurt, dry yeast, sugar, and Cheonggukjang(fermented soybeans) and adding warm water of 45°;C; (S12) Step of fermenting the raw material at a storage temperature of 35-45°;C for 7-10 days; (S13) Step of completing an eco-friendly fertilizer by adding cold water into the fermented raw material; (S14) Step of degassing for 2 days; (S15) Step of storing the eco-friendly fertilizer at room temperature;친환경 탈취제 제조방법이 개시된다. (a) 요구르트, 드라이이스트, 설탕, 청국장을 혼합한 후 섭씨 35도에서 섭씨 45도를 이루는 온수를 첨가하여 원재료를 제조하는 단계; (b) 상기 원재료를 섭씨 35도에서 섭씨 45도를 이루는 저장온도로 7~10일 동안 발효시키는 단계; (c) 상기 발효된 원재료에 냉수를 첨가하여 친환경 탈취제를 완성하는 단계를 포함하는 친환경 탈취제 제조방법이 제공된다.
