Abstract
A method is provided for controlling deposit-forming contaminants that comprise pitch or other fiber components which can interfere with the processing of the fibers, reduce paper quality, or both in papermaking systems. The method includes contacting fibers with a lipase and at least one peroxide source-free oxidant, and optionally nonionic surfactant, to liberate the organic contaminants from the fibers. Paper products of the method are also provided.
Claims29
