A process for manufacturing a cellulosic paper product (e.g., paper hand towels) exhibiting reduced malodor upon wetting. The process includes introducing a vanilla compound (e.g., vanillin) into the aqueous suspension of papermaking fibers from which the paper product is made, depositing the aqueous suspension of papermaking fibers onto a sheet-forming fabric to form a wet web and drying the wet web at high temperature in an oxidative environment to form a dried base sheet. The process of the present invention is particularly suited for reducing malodor released from cellulosic paper products made from through-air dried base sheet material.
