Methods to control organic contaminants in fibers are described. One method involves contacting the fibers with a composition containing water-soluble cellulose derivative and ester hydrolyzing enzyme, for a sufficient time and in a sufficient amount to control the organic contaminants present in the fibers. This method is effective to reduce stickies in paper mill furnish formed with recycled fibers. A method for pitch control in paper mill furnish formed with virgin fibers is also provided by the addi-tional inclusion of lipoxygenase in the composition. Resulting paper products formed from the processed fibers are also described as well as methods to make them.

La présente invention concerne des procédés permettant de contrôler des contaminants organiques présents dans des fibres. Un procédé consiste à mettre les fibres en contact avec une composition contenant un dérivé cellulosique soluble dans l'eau et une enzyme hydrolysante pendant un temps suffisant et en quantité suffisante pour pouvoir contrôler les contaminants organiques présents dans les fibres. Ce procédé permet de réduire efficacement les matières collantes dans les produits de papeterie fabriqués à partir de fibres recyclées. Cette invention concerne également un procédé de contrôle de la poix dans les produits de papeterie réalisés à partir de fibres vierges grâce à l'ajout de lipoxygénase dans la composition. Les produits en papier issus de ces fibres traitées sont également décrits ainsi que leurs procédés de fabrication.
