Zusammenfassung:	The present invention relates to an enzymatic method for removing sulphite. In particular, the present invention relates to a method for converting sulphite present in a composition into thiosulphate, comprising the introduction of 3-mercaptopyruvate sulphurtransferase (3-MST) and a substrate of said 3-mercaptopyruvate sulphurtransferase into said composition. The present invention can be used in particular in the pharmaceutical, cosmetic, food and chemical fields, and any field involving the use of sulphite. La présente invention se rapporte à un procédé enzymatique d'élimination du sulfite. En particulier, la présente invention se rapporte à un procédé de transformation du sulfite présent dans une composition en thiosulfate comprenant l'introduction dans ladite composition de 3- mercaptopyruvate sulfurtransférase (3-MST) et d'un substrat de ladite 3- mercaptopyruvate sulfurtransférase. La présente invention trouve des applications notamment dans le domaine pharmaceutique, cosmétique, agroalimentaire, chimique et tout domaine impliquant l'utilisation de sulfite.
