Relating to the field of removal of fungal toxins, the invention discloses a compound enzyme, an additive, application thereof and a method for removal of fungal toxins. Specifically, the invention relates to a compound enzyme, which contains amidase and esterase and can remove fungal toxins, especially fumonisins, ochratoxins and T2 toxin, additives containing the compound enzyme and applicationthereof in removal of fungal toxins, especially fumonisins, ochratoxins and T2 toxin, and a method for removal of fungal toxins. According to the technical scheme, combined use of the amidase and esterase can achieve simultaneous removal of ochratoxin A, fumonisins and T2 toxin, the removal efficiency is greatly improved than single use of one enzyme, and vomitoxins, aflatoxins and zearalenone toxin can be removed to certain degree.
