Abstract There is disclosed a chewing toy item for animals, typically for household pets such as dogs, which has permanent flavor and odor components. The flavor and odor components are thoroughly impregnated into the Nylon substrate of the toy item. These flavor and odor components are prepared by cooking of meat and animal by-products in a pressured, steam atmosphere out of contact with a liquid phase and the volatilized flavor and odor components are condensed and absorbed in a contiguous liquid phase within the cooking vessel. This produces an impregnating solution which is free of solids and suspended liquids, such as meat particles and fat globules, which will thoroughly impregnate the Nylon substrate of the toy item without the formation of a protective or isolating film on the outer surfaces thereof. The impregnation is achieved by immersing the preformed toy item within the aqueous solution in the cooking vessel and subjecting the toy item to prolonged contact with the solution, e.g., for periods from about 7-20 hours at cooking conditions, e.g., a pressure from 15 to about 60 psia and a temperature from 210* to about 290* F. The resultant product is a useful chewing toy item for animals which is thoroughly and permanently impregnated with meat flavor and odor components and which, therefore, retains a high attractiveness to animals throughout its useful life.
A method for the manufacture of a chewing toy and the like for animal pets which comprises: a. forming a toy item in the shape of a bone and the like from a Nylon molding resin having a water absorbency from 0.5 to about 5 weight percent. b. dissolving meat odors and flavors in an aqueous impregnating solution while maintaining said solution free of suspended solid and fat materials by subjecting meat or animal byproducts to steam at a temperature from 210* to about 280* F. and autogenous pressure for a period from 3 to about 20 hours while in the presence of, but out of contact with, water; and c. immersing said toy item in said aqueous impregnating solution and maintaining it therein for a period of time from 3 to about 20 hours at a temperature from 210* to about 280* F. autogenous pressure.
