산화 반응에서 부생하는 과산화수소를 신속하게 분해하는 카탈라아제 제제를 사용하여, 중합도 2이상의 전분 분해 산화물 혹은 전이 반응 산화물로 당카르본산을 공업적으로 또한, 고수율로 생산하는 방법을 제공하는 것. 환원 말단에 글루코오스 잔기를 갖는 중합도 2이상의 전분 분해물 또는 전이 반응물의 환원 말단 측의 알데히드기가 산화된 당카르본산의 제조 방법은 당질 산화 시에 과산화수소를 부생하는 당질 산화 효소제를 카탈라아제 제제의 존재하에, 상기 전분 분해물 혹은 전이 반응물을 포함하는 원료 기질로 작용시키는 공정을 포함하고, 작용 공정의 반응액 총량이 1L 이상이며, 염기성 화합물을 작용 공정중에 소정량 첨가함과 동시에, 작용 공정 개시 시에, 염기성 화합물로서 탄산염 또는 탄산수소염을, 상기 소정량의 5% 이상의 상당 질량으로 첨가한다. 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.
