Appl. No.:

10/731257

Inventors:

Frank Jay Hague - Plano TX 75025

International Classification:

A01K 2900

US Classification:

119709, 119710, 426315

Abstract:

Pigskin is processed to provide a bleached, expanded skin used in dog treat or chew products. The raw pigskin is dehaired and then daubed with an alkali mixture of an alkali liquid, alkali enzymes and lime, the mixture having a pH of greater than or equal to 12. The alkali mixture dissolves the colloidal protein. The alkali is removed by alternately rinsing the skin in water and agitating the skin with first ammonium chloride, or chloride sulphate or ammonium sulphide, and then second with ammonium chloride, or chloride sulphate or ammonium sulphide, and pancreatic enzymes. The skin is agitated with sodium carbonate and a degreaser to remove the fat. The skin is then washed with hydrogen peroxide, which bleaches and expands the skin. The skin is then formed into a dog product and dried.

Inventors:

Frank Jay Hague - Plano TX, US

International Classification:

A01K029/00
A23B004/027

US Classification:

119710, 426315

Abstract:

A chew product for use by animals is made of skin such as rawhide or pigskin. The skin is infused with chlorophyll or mint or both to freshen a dog's breath and also with sugar to increase palatability. The interior portion of the skin can be perforated, such as by cutting, before the skin is formed into a product. The perforations allow a dog's teeth to penetrate into the product and be scraped clean by the edges of the perforations. The skin is dyed green from the chlorophyll. The dyed skin can be used either alone or in conjunction with another color skin to make a product. The dyed skin and a bleached white skin combine to make an attractive product.
