摘要: Dialdehyde carbohydrates such as dialdehyde starch (DAS) can be oxidised with oxygen or hydrogen peroxide in the presence of a laccase or another enzyme capable of oxidation. The oxidation is mediated by a di-tertiary nitroxyl such as TEMPO. The products contain both aldehyde groups and carboxyl groups and have excellent properties as wet strength agents.
