| titleOfInvention | Method for producing sugar carboxylic acid |
| abstract | To provide a method for industrially producing a sugar carboxylic acid from an oxidized starch decomposition product or oxidized transfer reaction product having a degree of polymerization of 2 or more in a high yield, using a catalase formulation which quickly decomposes hydrogen peroxide produced as a by-product in the oxidation. A method for producing a sugar carboxylic acid in which an aldehyde group on a reducing end of a starch decomposition product or starch transfer reaction product having a degree of polymerization of 2 or more and having a glucose residue at the reducing end is oxidized, the method comprising a step of treating a raw material substrate containing the starch decomposition product or starch transfer reaction product in the presence of a catalase formulation with a carbohydrate oxidase agent producing hydrogen peroxide as a by-product in carbohydrate oxidation, wherein a total volume of a reaction liquid in the treatment step is 1 L or more, wherein a predetermined amount of a basic compound is added during the treatment step; and wherein a carbonate or a hydrogen carbonate is added as the basic compound in an amount by mass corresponding to 5% or more of the predetermined amount at a start of the treatment step. |
