Abstract: A receptacle is provided for containing and displaying food products which tend to exude juices or liquids, and which comprises a supporting member, such as a tray or bag, and an absorbent pad associated therewith. The absorbent pad comprises a mat of liquid absorbent material, an upper liquid impermeable sheet overlying the absorbent mat, and a perforated bottom sheet underlying the absorbent mat. When a food product is positioned upon the upper sheet of the absorbent pad, any exuded liquids will flow around the pad and enter the mat by capillary action through the perforated openings of the bottom sheet, and the liquids will be held out of contact with the food product to thereby minimize contamination of the product and maintain its appearance and improve its shelf-life. The pad also has independent utility as a moisturizing device for use in closed food containers or packages.
