A novel article and method are disclosed for reducing malodor in disposable products for the absorption of body fluids. An effective amount of pentitol is applied to a disposable absorbent material, prior to its use. In one aspect, the invention provides a water-swellable, water-insoluble, hydrogel-forming polymeric absorbent material. In one aspect, the pentitol is compositionally part of the absorbent structure or is coated on the absorbent material present in the absorbent structure. The pentitol preferably is located in the area of insult, i.e., that area of the absorbent product to be exposed to the body fluid intended to be absorbed. The pentitol in the novel article and method of the present invention is a compound selected from the group consisting of ribitol, D-arabinitol, L-arabinitol, and xylitol or a combination of one or more compounds selected from the group consisting of ribitol, D-arabinitol, L-arabinitol, and xylitol effective in preventing malodor.
