The economics of cold food pasteurization are governed by a number of factors, including: the type of ionizing radiation source (X-Ray, or Gamma), cost and power of the source, pasteurization dose, location of the pasteurization facility, facility capacity factor, and the annualized costs. Using a costing procedure developed by Morrison [1], calculations for typical sources, locations, etc., have been updated using facility cost estimates prepared by a major U.S. construction firm and scalings from the Morrison data.The "owner's cost" per pound of product is a function of the facility scale, showing an asymptote at ~ 100 kT (220 million pounds) per year of product. Likewise, the owner's cost significantly depends on the annualization interest rate. A "stand-alone" location of the pasteurization facility has an effect on the cost of the process due to the need to transport product from the meat plant to the facility, the labor for unloading and loading the product at the facility, and the unshared G&A costs at the facility. This increases processing costs and "borrows" into the shelf-life value of the product. An "integrated" location of the pasteurization facility (at the meat plant) minimizes processing cost (inclusive of special labeling) and best fits the operating characteristics of a typical meat plant (2 shift, 5 day week).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
