Definitions

  • This invention relates to a process for inhibiting or a combination thereof preventing the spoilage of meat, poultry, fish, shellfish and products thereof.
  • slaughter-dressing practices include a rapid succession of steps which include killing the animal, draining the blood, removing the integumentary covering and viscera, trimming off any obvious areas of fecal or visceral contamination, and refrigeration of the carcass. Due to the potential contamination of the carcass (meat and poultry) during the slaughter and dressing processes, better techniques for slaughter-dressing are being sought to reduce microbial contamination. Such improvements in decontamination of the meat and poultry are also sought to prolong the shelf-life of these food products.
  • Techniques which are being studied include steam sterilization, treatment with lactic, acetic or citric acid, treatment with a bacteriocin, such as nisin, irradiation with ultraviolet light or ionizing radiation, and surface chlorination with hypochlorite or chorine dioxide. No method is completely successful in decontaminating animal carcasses .

  • antimicrobial compounds for use in the processes of the present invention are commercially available or may be obtained by those of ordinary skill in the art without undue experimentation using common synthetic routes disclosed in the art.
  • the contacting of the EDTA and antimicrobial agents in the process of the present inventions includes application of the EDTA and antimicrobial agents to the food products by spraying, dipping the food products in solutions of these compounds or placing the food products in a bath containing EDTA or a combination thereof an antimicrobial agent.
  • the EDTA and antimicrobial agent can be present in one solution and thus the food product is exposed to both the EDTA and antimicrobial agent in one step.
  • the food product can be contacted with the EDTA and antimicrobial agent in two successive steps, for example, spraying a carcass with a solution of EDTA followed by spraying the carcass with an antimicrobial agent.
  • effective amount it is meant that the EDTA and antimicrobial concentrations are more effective in removing microorganisms from the meat, poultry, fish or shellfish than the use of water alone during the washing process or at a concentration so that a sufficient amount of EDTA and antimicrobial agent adheres to the food product to prevent or inhibit the growth or metabolism of a microorganism.
  • the concentration and pH of EDTA solutions for use in the present invention is adjusted for optimal effect in removal of microorganism from the meat or poultry.
  • the pH of the EDTA solution is generally between about pH 3 and pH 9 to produce maximal removal of bacterial lipopolysaccharide .
  • the preferred pH of the EDTA solution is between about 6 and 8.5.
  • the concentration of the EDTA can be adjusted and will be dependent on the expected microbial load in the process and can be optimized for each slaughter house.
  • the EDTA used will be between about 0.001 and about 0.3 molar.
  • the concentration of the EDTA is between about 0.005 and about 0.20 molar. More preferably the concentration of the EDTA is between about 0.05 and about 0.10 molar.

  • the vehicle or carrier for making the EDTA and antimicrobial solutions is generally any vehicle in which the respective agents are soluble and which is safe for human consumption.
  • the EDTA and antimicrobial agents are solution with water as the carrier.
  • the amount and duration of the spray is generally sufficient to remove all the observable fecal contamination and to wet all observable surfaces.
  • the duration of the washing will depend upon the specific meat and the slaughter house. For example, the time to place a poultry carcass in a dip and removal will generally be shorter than the time necessary to place and remove a beef carcass from such a dip. Generally the time for such washing will be between about 0.05 and about 10 minutes.
  • EDTA and antimicrobial compound are preferably contacted with the meat or poultry after removal of the skin or hide and the removal of the viscera. In slaughter house operations, this contacting is preferably done within 15 minutes of the death of the animal.
  • the EDTA and antimicrobial compound are preferably contacted with the meat or poultry by spraying.
  • the EDTA and antimicrobial compounds are preferably applied at the time of removal from the water. For fish, there could be multiple applications, for example, upon removal from the water and again during the cleaning process.
  • the concentration and temperature of application of the EDTA and antimicrobial compounds are as those specified above for meat and poultry.
  • the EDTA and antimicrobial compounds at the temperature and concentrations specified above can be applied to the wound using standard procedures in the art.
  • Example 1 Upon pulling in the nets on a shrimp boat, the shrimp were immediately placed in a tank containing an aqueous solution of 0.05 molar EDTA and 0.03 g% cetylpyridinium chloride at pH 8 and 10 degrees Celsius. They were maintained in this solution until delivery to the processing plant.
  • Example 2 At a beef processing plant, a cow was killed and hung by the hind legs to drain the blood from the neck. The hide was removed and the animal was eviscerated. Some fecal contamination occurs during the evisceration process and the visible fecal contamination was removed by trimming. Immediately following the trimming and within 8 minutes from the time evisceration of the animal began, the carcass was sprayed with a 0.05 molar aqueous solution of EDTA at pH 7 and temperature 37 degrees Celsius for 30 seconds so that every surface of the carcass was thoroughly flushed with the solution. The carcass was then immediately sprayed for 30 seconds so that every surface was thoroughly flushed with a solution of 5 weight percent citric acid at a temperature of 37 degrees Celsius. The carcass was then moved into a freezer.
  • Example 3 At a beef processing plant, a cow was killed and hung by the hind legs to drain the blood from the neck. The hide was removed and the animal was eviscerated. Some fecal contamination occurs during the evisceration process and the visible fecal contamination was removed by trimming. Immediately following the trimming and within 8 minutes from the time evisceration of the animal began, the carcass was sprayed with a 0.05 molar aqueous solution of EDTA and 5 weight percent sorbic acid at a temperature of 37 degrees Celsius and a pH of 6.5 for 30 seconds at such a flow rate that all the surfaces of the carcass were thoroughly flushed with the solution. The carcass was then moved into a freezer.
  • Example 4 Upon pulling up the nets upon a fishing vessel, the fish were immediately placed in a tank containing an aqueous solution of 0.03 molar EDTA and 1 weight percent acetic acid at pH 6.5 and 5 degrees Celsius. The fish were maintained in this solution until delivery to a processing plant. At the processing plant, the fish were descaled and gutted. Immediately after the gutting procedure, the fish were dipped in a bath of 0.1 molar EDTA solution at pH 7 with adequate agitation to rinse all surfaces of the fish. The fish were then dipped in a bath of 3 weight percent citric acid with adequate agitation to rinse all surfaces of the fish.
  • Example 5 A chicken was entered into a slaughter-dressing plant where it was killed, drained of blood, and scalded to remove the feathers. The chicken was eviscerated. Immediately following the evisceration, all surfaces of the chicken were rinsed with an aqueous solution of 0.1 molar EDTA solution at pH 7 and 37 degrees Celsius for 30 seconds. The chicken was then rinsed with a 0.2 weight percent solution of sorbic acid at 37 degrees Celsius and pH 7 so that all surfaces were thoroughly wetted
