Thirteen materials, two ethyl cellulose formulations, one emulsifiable polyethylene, and ten petroleum waxes, were studied as possible materials for dip coating meat products. As a result of blocking, impact, and water vapor transmission tests, three materials were used to dip coat pork roasts and chickens: Dow Ethocel X2203.10, Wasco WA/3994, and Kalamazoo Paraffin formulation KP4, The Dow material was considered to be the best as it did not oil off as much as the Wasco Pak, whereas the petroleum wax did not withstand impact or blocking tests. The polyethylene was too brittle and also contained toxic materials. When used as dip coatings for pork roasts and chickens and for cooked pork roasts and cooked game hens, all three materials provided adequate protection from weight loss when stored at 0 deg -F for one year. Panel evaluations for acceptability and chemical analyses for TBA revealed no consistent trends. Cooked pork roasts and game hens irradiated at six megarads were scored significantly lower than the unirradiated items. The materials did not provide adequate protection to cooked, irradiated pork roasts and game hens for storage at 100 deg F, 90% R.H. (auth)
