Description

BACKGROUND OF THE INVENTION

[0004] This invention relates to a method for processing meat products and other ingredients to produce a fully cooked or oven roasted shelf stable meat product. Further, this invention relates to a method comprising a series of mixing, injecting and/or tumbling, cooking or roasting, chilling, packaging, and pasteurization resulting in a fully cooked or oven roasted meat product that has a taste and texture similar to that of freshly cooked or roasted meat. Said product will remain free from pathogen-causing levels of bacteria and can be stored for an extended period of time without refrigeration due to antimicrobial properties of the ingredients used.

[0005] Approximately two-thirds of the world population does not have access to refrigeration for storing food products that would be lost due to spoilage without refrigeration. As a result, this group of the world population does not have access to consuming meat products that require refrigeration. All meat products contain meat proteins that are a source of good nutrition in the human diet. Meat and meat products have historically been an important part of the diet in parts of the world where refrigeration is common. The method and product described herein provides a source of meat protein that has an extended shelf life without refrigeration and also a texture and flavor similar to that of a freshly cooked or roasted meat product. Other flavoring ingredients can be added to provide products for acceptance within a particular culture.

[0006] USDA has certain government regulations that must be met for a product to be classified as shelf stable. Good Manufacturing Practices that will provide for a shelf stable product must be met in other areas of the world where USDA does not have jurisdiction. Shelf stable meat products must be able to be stored for extended periods of time without refrigeration without compromising product quality and flavor due to microbial deterioration or oxidative reduction. For a shelf stable meat product to be safe for consumption, the product should be able to inhibit mold and yeast growth, reduce the growth rates of microorganisms present, and inhibit the growth of new bacteria. The shelf stable meat product must maintain a favorable taste.

[0007] The term “shelf stable product” refers to a product that is preferred to have a mouth feel and texture that is similar in mouth feel and texture to freshly cooked product. The product must exhibit properties that enable the product to resist significant levels of microbial growth when stored without refrigeration for an extended period of time. The shelf stable product depends on the amount of moisture available for microorganism growth and nutritive support, on the pH of the product, on the oxygen availability, and on the proper initial cooking conditions among other elements. The proper selection of ingredients used to manufacture the product is also important.

[0008] U.S. Pat. No. 4,358,468 issued to Dolan, et al. discloses a method of cooking vegetable proteins to produce a pet food that resembles lean meat marbled with fat. Shelf stability of this product is achieved by using unspecified amounts of aqueous solutes. This technology does not, however, utilize meat as the predominant ingredient.

[0009] U.S. Pat. No. 4,798,729 issued to Anders, et al. describes a method for delaying Clostridium botulinum growth in a foodstuff selected from the group consisting of fish and poultry by adding a lactate salt to the fresh foodstuff in an amount of 1% to 7% by cooking the foodstuff at high humidity to a temperature sufficient to cook the foodstuff, but not sufficient to sterilize the foodstuff, by cooling the cooked foodstuff, and by packaging the foodstuff in a plastic barrier package.

[0010] U.S. Pat. No. 4,888,191 issued to Anders, et al. describes a method for delaying Clostridium botulinum growth in a foodstuff selected from the group consisting of fish and poultry by adding a lactate salt to the fresh foodstuff in an amount of 1% to 7% by packaging the foodstuff in a plastic barrier package, by cooking the foodstuff at high humidity to a temperature sufficient to cook the foodstuff, but not sufficient to sterilize the foodstuff, and by cooling the cooked foodstuff.

[0011] U.S. Pat. No. 5,300,312 issued to Lusas, et al. describes a method of processing vegetable protein with other ingredients by extrusion cooking, after which meat products are added to produce an intermediate moisture vegetable food product resembling meat. This method requires mechanical drying and re-extrusion to produce the final product. This two-step extruded product utilizes a process and ingredients approved by the FDA, rather than the USDA.

[0012] U.S. Pat. No. 5,945,152 issued to Purser discloses a method mixing ingredients that act as antimicrobials and other ingredients used for controlling end product water activity and cooking the mixture resulting in pasteurization using a scraped surface heat exchanger for pasteurization. The product is then cooled to ambient temperature and packaged under anaerobic vacuum using a moisture/microbe impermeable barrier.

BRIEF SUMMARY OF THE INVENTION

[0013] This invention relates to a method of preparing a fully cooked or oven roasted shelf stable meat product comprising of first mixing a selected group of ingredients into a brine solution; injecting the brine solution and/or tumbling the brine solution with the selected meat product to create a homogeneous mixture; fully cooking or oven roasting the blended meat product to meet USDA regulations; chilling the cooked product; forming, cutting, shaping, or styling the product; packaging the product; and pasteurizing the finished product.

[0014] The invention also relates to a food product prepared by the method described above.
