FIBER OXIDASE COMPOSITION USED FOR ALTERING AND IMPROVING WHITENESS OF PAPER, PAPERMAKING METHOD, AND APPLICATIONS OF THE COMPOSITION

摘要

Provided are a fiber oxidase composition used for altering and improving the whiteness of a paper, a papermaking method, and applications of the composition. The fiber oxidase composition comprises the following components: an enzyme component having an oxidation function for a fiber, where the enzyme component is a fiber oxidase that alters the surface properties of the fiber by means of a redox reaction; and, an auxiliary component having increased catalytic activities for the fiber oxidase, where the auxiliary component is a scavenger for a reaction product of the fiber oxidase, and the weight ratio of the enzyme component to the auxiliary component is 1:0.1-50.
