Abstract: Methods to control lipophilic extractives in Acacia pulp and fibers are described. One method involves contacting the pulp or fibers with a composition containing at least one enzyme, such as at least one esterase or lipase or both, for a sufficient time and in a sufficient amount to control the lipophilic extractives present in the pulp or fibers.

Abstract: Un método para controlar los componentes lipofílicos presentes en fibras vírgenes de acacia que contengan componentes lipofílicos, que comprende crepar una banda de fibra de dichas fibras vírgenes de acacia con una composición que contiene al menos una esterasa o lipasa, o ambas, durante un tiempo suficiente y en una cantidad suficiente para controlar los componentes lipofílicos presentes en las fibras vírgenes de acacia, en el que dicha puesta en contacto es anterior, simultánea o posterior a dicho crepado.

Abstract: Methods of making paper or paperboard are described. According to one of the methods, an acidic aqueous alumina sol is introduced to a papermaking pulp to form a treated pulp having improved retention properties. The acidic aqueous alumina sol preferably has a pH of from about 3 to about 6. The sol preferably contains elongate secondary particles which are elongated from about 50 nm to about 300 nm in only one plane and formed by edge-to-edge coagulation of rectangular plate like primary particles having a length on one side of from about 10 nm to about 30 nm when observed through an electron microscope. The pulp may also be treated with at least one coagulant, at least one flocculant, at least one cationic starch, at least one cellulytic enzyme, at least one biocide, and/or other conventional papermaking pulp additives. The resulting pulp is formed into a sheet of pulp and then drained to form a paper or paperboard. Other papermaking processes are also described as is a papermaking apparatus for carrying out the methods. Paper and paperboard containing dried pulp that has been treated with an acidic aqueous alumina sol are also described. Methods to flocculate particulate materials in a dispersion are also described.
