Provided is a method for preparing detoxified sulfur, the method comprising the following steps: diluting diastase enzyme liquid into 10% diluted liquid putting sulfur in a container and immersing the sulfur in the diluted diastase enzyme liquid detoxifying the sulfur by aging the same for approximately one week and washing the detoxified sulfur with water, drying, grinding, and packaging the same. In addition, provided is a method for preparing detoxified sulfur, the method comprising the following steps: providing a mixed enzyme solution having a concentration of 5-20% by diluting a mixed enzyme of alcalase and Viscozyme TML with water obtaining detoxified sulfur by immersing sulfur in the solution and aging the same for 6-7 days making the detoxified sulfur into a liquid phase by heating the detoxified sulfur at 110-120°C, and then adding an alkali solution into the same to maintain a pH of 9-11 and, subsequently, obtaining heavy metal hydroxide inserting the heavy metal hydroxide, obtained in the earlier step, into activated carbon, agitating the same for 10 minutes or longer, and then inserting a coagulant, and filtrating and performing the separation with a high pressure dehydration device and obtaining particulates as final products by neutralizing a filtrate, with weak acid, to have a pH of 7.5-8.5. According to the present invention, the method for manufacturing detoxified sulfur has simple processes, requires low production costs, and is capable of mass production. The detoxified sulfur is not eliminated even when the detoxified sulfur is mixed into feed for poultry, livestock, fish and shellfish, and so on. The detoxified sulfur can reduce the mortality rate, increase the rate of absorption into meat, enhance quality and flavor, and increase the growth and productivity of livestock.COPYRIGHT KIPO 2017본 발명은 디아스타제 효소 원액을 10% 묽은 액으로 희석시키는 단계 유황을 용기에 넣고 상기 희석된 디아스타제 효소액에 침지시키는 단계 약 1주일 동안 숙성하여 제독하는 단계 및 상기 제독된 유황을 물로 세척하여 건조, 분쇄 및 포장하는 단계를 포함하는 법제 유황의 제조방법
