Abstract
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.
Claims15
A method for treating a composition, comprising introducing into said composition 3-mercaptopyruvate sulfurtransferase (3-MST) and a substrate of said 3-mercaptopyruvate sulfurtransferase in order to convert sulfites in the composition into thiosulfates, wherein the composition is an agri-food, pharmaceutical, cosmetic or veterinary composition.
A method for converting sulfite present in a composition into thiosulfate, comprising introducing into said composition 3-mercaptopyruvate sulfurtransferase (3-MST) and of a substrate of said 3-mercaptopyruvate sulfurtransferase and converting the sulfite present in the composition into thiosulfate, wherein the composition is an agri-food, pharmaceutical, cosmetic or veterinary composition.
