1. An absorbent food pad comprising: an absorbent or superabsorbent medium that includes a top sheet and a bottom sheet separated by an absorbent core, wherein the top sheet and the bottom sheet are made of a film, and wherein the absorbent or superabsorbent medium absorbs a liquid purge up to an amount of a nominal absorbency of the absorbent food pad;an oxygen scavenging system in the absorbent or superabsorbent medium,wherein the oxygen scavenging system is selected from the group consisting of metal oxidation component, enzyme catalyzed oxidation component, and combinations thereof,wherein the oxygen scavenging system is present in the absorbent or superabsorbent medium in an amount between about 1 wt % to about 10 wt % based on the nominal absorbency of the absorbent food pad,wherein the oxygen scavenging system is activated by contact with the liquid purge that is absorbed by the absorbent or superabsorbent medium, andwherein the oxygen scavenging system reduces oxygen concentrations to less than 0.5% oxygen within 48 hours from an initial 5% oxygen in a package in which the absorbent food pad is placed and remains greater than zero and less than 0.5% for approximately 11 days. 2. The absorbent food pad according to claim 1, wherein the enzyme catalyzed oxidation components are selected from the group consisting of oxidoreductase, invertase, amylase, maltase, catalase, dehydrogenase, oxidase, glucose oxidase, hexose oxidase, oxygenase, peroxidase, cellulase, and any combinations thereof. 3. The absorbent food pad according to claim 1, wherein the metal oxidation components comprise: an oxidizable metal selected from the group consisting of iron, zinc, copper, aluminum, tin, and any combinations thereof; anda catalyst selected from the group consisting of acid, water, and combinations thereof. 4. A method for enhancing appearance attributes and extending shelf life of a food product, comprising: packaging the food product with the absorbent food pad according to claim 1,wherein the appearance attributes include color, aroma, and overall appearance of the food product. 5. The absorbent food pad according to claim 1, wherein the oxygen scavenging system is present in the absorbent or superabsorbent medium in an amount between about 2 wt % and about 8 wt %. 6. An absorbent food pad comprising: an absorbent or superabsorbent medium that includes a top sheet and a bottom sheet separated by an absorbent core, wherein the top sheet and the bottom sheet are made of a film, and wherein the absorbent or superabsorbent medium absorbs a liquid purge up to an amount of a nominal absorbency of the absorbent food pad; andan oxygen scavenging system present in the absorbent or superabsorbent medium,wherein the oxygen scavenging system comprises an enzyme selected from the group consisting of oxidoreductase, invertase, amylase, maltase, catalase, dehydrogenase, oxidase, glucose oxidase, hexose oxidase, oxygenase, peroxidase, cellulose, and any combinations thereof,wherein the oxygen scavenging system is activated by contact with the liquid purge that is absorbed by the absorbent or superabsorbent medium, andwherein the oxygen scavenging system reduces oxygen concentrations to less than 0.5% oxygen within 48 hours from an initial 5% oxygen in a package in which the absorbent food pad is placed and remains greater than zero and less than 0.5% for approximately 11 days. 7. The absorbent food pad according to claim 6, wherein the enzyme comprises glucose oxidase and catalase. 8. An absorbent food pad comprising: an absorbent or superabsorbent medium that includes a top sheet and a bottom sheet separated by an absorbent core, wherein the top sheet and the bottom sheet are made of a film, and wherein the absorbent or superabsorbent medium absorbs a liquid purge; andan oxygen scavenging system present in the absorbent or superabsorbent medium,wherein the oxygen scavenging system is selected from the group consisting of: metal oxidation components, enzyme catalyzed oxidation components, and combinations thereof,wherein the oxygen scavenging system is present in the absorbent or superabsorbent medium in an amount between about 2 wt % to about 8 wt % based on a nominal absorbency of the absorbent food pad, wherein the nominal absorbency is between about 50 grams and about 75 grams of liquid,wherein the oxygen scavenging system is activated by contact with the liquid purge that is absorbed by the absorbent or superabsorbent medium, andwherein the oxygen scavenging system reduces oxygen concentrations to less than 0.5% oxygen from an initial 5% oxygen within 24 hours in a food package in which the absorbent food pad is located and remains greater than zero and less than 0.5% for approximately 11 days. 9. The absorbent food pad of claim 1, further comprising a reaction promoter within the absorbent food pad that attracts moisture. 10. The absorbent food pad according to claim 9, wherein the reaction promoter is a humectant selected from the group consisting of polyethylene glycol, polypropylene glycol, glycerin, glycerol, and any combinations thereof. 11. The absorbent food pad according to claim 9, wherein the reaction promoter is a self-propagating agent. 12. The absorbent food pad according to claim 6, further comprising a reaction promoter within the absorbent food pad that attracts moisture. 13. The absorbent food pad according to claim 12, wherein the reaction promoter is a humectant selected from the group consisting of polyethylene glycol, polypropylene glycol, glycerin, glycerol, and any combinations thereof. 14. The absorbent food pad according to claim 12, wherein the reaction promoter is a self-propagating agent. 15. The absorbent food pad according to claim 8, further comprising a reaction promoter within the absorbent food pad that attracts moisture. 16. The absorbent food pad according to claim 15, further comprising wherein the reaction promoter is a humectant selected from the group consisting of polyethylene glycol, polypropylene glycol, glycerin, glycerol, and any combinations thereof. 17. The absorbent food pad according to claim 15, wherein the reaction promoter is a self-propagating agent.
