Meet our Associate Member April Spotlight: TEWARI DE-OX SYSTEMS, INC.








Describe your business, your clients and the products/services you provide.

Tewari De-Ox Systems has invented and patented an oxygen scavenging packaging technique for greatly extending the shelf life of meat and poultry processed in a centralized meat packing operation. Our solution is unlike any other, capable of increasing shelf life of meat products by completely eradicating oxygen content surrounding the meat. The Tewari De-Ox systems’ Zero-OxTech® [US & International Patents Pending] accomplishes longer shelf lives for all proteins [red meat as well as poultry] by focusing on preserving the enzymatic activity of the meat muscle that prevents the meat from discoloring and otherwise deteriorating, in addition to synergistic effects delaying microbial growth.

How your business benefits the red meat industry?

Tewari’s Zero-OxTech offers several weeks of shelf-life during distribution and several days at the retail-shelf, thereby giving the red meat industry to centralize their operations and expand to untouched territories. Shelf-life offered by Tewari’s process is as follows: 
Shelf-life                                                    Tewari’s Zero-OxTech®
Storage/Distribution days                          70 to 105 days
Retail Display                                            5 to 9 days±
Meat color                                                 Red

What innovative new products/services are you working on?

The Tewari system eliminates the need for vacuum packaging of store ready packaged fresh meat. Steaks, chops and other cuts of fresh meats can actually be shipped pre-packaged in “CONVENTIONAL FOAM-TRAYS” as store ready packs without the need for vacuum packaging. Equipment that is already in most packers’ processing lines can be used so that no additional capital is required. This is totally different than any other oxygen scavenging processes now in the market. Additionally, none of these processes reduce total oxygen to ABSOLUTE ZERO PPM levels like the Tewari De-Ox system.

Tell us about your people. What sets them apart from your competition?
