Food preservation systems
View Patent ↗The present invention provides a food preservation system that includes a multi-phase bacterial inhibition food pad. The food pad includes absorbent media and/or material to absorb fluids emanating from the packaged food. The absorbent media/material includes one or more bacterial inhibitors that may possess bacteriostatic and/or bactericidal properties. In addition, the food pad may also include an atmosphere modification system capable of modifying an atmosphere in a food package. Optionally, one or more reaction promoters and/or one or more mechanisms to protect the food preservation system may also be included in the food pad. Overall, the food preservation system inhibits bacterial growth, thereby enhancing food preservation and/or food safety.
1. A multi-phase bacterial inhibition food pad comprising:
an absorbent or superabsorbent medium;
one or more organic acid bacterial inhibitor present in said absorbent or superabsorbent medium in an amount of about 1 wt % to about 3 wt % based on a nominal absorbency of the food pad, wherein the one or more organic acid bacterial inhibitor inhibits growth of bacteria in a liquid purge from a meat in the food pad; and
an O 2 scavenging system, wherein the O 2 scavenging system comprises one or more metal oxidation components, one or more enzyme catalyzed oxidation components present in said absorbent or superabsorbent medium in the food pad in an amount between about 1 wt % to about 10 wt % based on a nominal absorbency of the food pad, or any combinations thereof.
2. The multi-phase bacterial inhibition food pad of claim 1 , wherein said one or more metal oxidation components include a combination of at least one oxidizable metal and at least one catalyst, and wherein the at least one oxidizable metal is selected from the group consisting of iron, zinc, copper, aluminum, tin, and any combinations thereof, wherein the at least one catalyst is selected from the group consisting of acid, water, and any combinations thereof.
3. The multi-phase bacterial inhibition food pad of claim 1 , wherein said O 2 scavenging system comprises one or more enzyme catalyzed oxidation components selected from the group consisting of oxidoreductase, invertase, amylase, maltase, catalase, dehydrogenase, oxidase, glucose oxidase, hexose oxidase, oxygenase, peroxidase, cellulose, and any combinations thereof.
4. The multi-phase bacterial inhibition food pad according to claim 1 , further comprising:
a CO 2 generation system in an amount of about 0.5 wt % to about 10 wt % based on a nominal absorbency of the food pad.
