Edible tubular casings for meats, such as sausages are described. The casings are comprised of reconstituted collagen combined with natural casing material comprising bovine, porcine or sheep gut, or combinations thereof. Methods for producing the casings by forming a gel consisting of a combination of the natural material and the reconstituted collagen are also described.
A method for producing collagen casings having one or more flavor ingredients incorporated into the collagen is provided. The flavor ingredients may be added during processing of collagen to produce the collagen casing; prior to, during or after drying of the collagen casing; prior to, during or after humidification to add moisture to the collagen casing; prior to, during or after shirring of the collagen casing; prior to or after the casing has been stuffed with meat products; during cooking of the stuffed collagen casing; and/or prior to packaging of the meat product. The flavor ingredient may be a water based flavor ingredient, an oil based flavor ingredient, a powdered flavor ingredient, a microencapsulated flavor ingredient, or a combination of two or more of these types of flavor ingredients. Collagen casings having one or more flavor ingredients incorporated into the collagen casing are also provided.
Collagen casings comprising chitosan as an anti- microbial agent are provided. The collagen casings may be produced by adding chitosan during the gelling of quarter grind hides, by injecting chitosan into collagen gel prior to extrusion, or by applying a chitosan solution to a surface of extruded collagen casings.

COLLAGEN DOUGH AND METHOD FOR PRODUCING COLLAGEN DOUGH CONTAINING CHITOSAN
A hydrolyzed collagen dough produced from bovine collagen and methods for producing the collagen dough from bovine hides is provided. The collagen dough comprises water, bovine collagen, sodium benzoate and hydrochloric acid. To produce the collagen dough, the corium layer is separated from bovine hides and treated. The collagen dough may be used, for example, in biomedical applications, such as cell technology/tissue engineering, suture materials, or film and sponges for skin grafting. The collagen dough may further comprise chitosan.
Collagen casings having a final moisture content of between about 18.5% to 21.5% by weight may be produced by controlling the drying process for a collagen casing ready for drying. The collagen casing is treated with a suspension of polysorbate in vegetable oil following the drying process. The resulting collagen casing does not require treatment in a humidification chamber to increase the moisture content of the casing prior to shirring..
A device for applying liquid flavors to collagen casing is provided, in one embodiment, the device comprises a cup and a roller for applying liquid flavor to the surface of the collagen casing prior to drying. In another embodiment, the device comprises an applicator having a base plate with a first hole in the base plate to allow the collagen casing to pass through the base plate, a second hole in the base plate in fluid communication with the first hole to inject liquid flavor through the second hole into contact with the collagen casing as it passes through the first hole, a wiper removably attached to the base plate to wipe excess liquid flavor from the surface of the collagen casing, and a liquid flavor injection line attached to the second hole in the base plate, in some embodiments, the cup and roller are combined with the applicator to apply the liquid flavor.'

An improved collagen casing is produced by applying a suspension of a polysorbate in vegetable oil to the collagen film. The collagen casing exhibits improved qualities over collagen casing, such as reduced fading of dyed collagen casings when exposed to UV light.
