摘要： 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.
