Compositions and methods for inhibiting the deposition of organic contaminants from pulp in pulp and papermaking systems are disclosed. The methods add to the pulp or to the deposition prone surface of the papermaking system a composition comprising a polyvinyl alcohol having 50 to 100% hydrolysis, a high molecular weight gelatin having a molecular weight of about 100,000 or higher, and a cationic polymer.
