An absorbent structure for collecting and retaining exuded fluids from food products such as meat and poultry is disclosed herein. The structure has a fluid permeable top sheet and a fluid impermeable bottom sheet with an absorbent core of pulp coform material located therebetween. In a preferred embodiment the periphery of the top and bottom sheets are sealed to form a pouch and the pulp coform material is stratified into a first top layer and a second bottom layer. Superabsorbents such as carboxymethylcellulose may be added to the coform material to aid in fluid retention. In the preferred embodiment the superabsorbent is located in the bottom layer of pulp coform while the top layer of the pulp coform is substantially devoid of the superabsorbent.
