摘要：A method is provided for preventing, minimizing, and/or eliminating the migration of mineral oils from paper food packaging into packaged food. The method can include adding a copper-containing oxidase enzyme, such as a laccase enzyme, to a paper pulp from which the paper food packaging is to be formed. The migration of mineral oils originating from residual inks in recycled old corrugated containers and old newsprint, is particularly suppressed, including the migration of C10-C25 fractions of aromatic mineral oil hydrocarbons and of saturated mineral oil hydrocarbons.
