Patent number: 4563231Abstract: Disclosed is a tubular casing of fiber-reinforced regenerated cellulose comprising a film web which is curved to form a tube. The edge regions of the film web, which run parallel to the longitudinal axis, abut or overlap slightly and are sealed by means of a film strip which covers both the edge regions. The film web and the film strip composed of the same material have, in the wet remoistened stage, a breaking strength of about 15 to 30 N/mm.sup.2 and an elongation at break of about 30 to 50% in the longitudinal direction of the web, and a breaking strength of about 15 to 35 N/mm.sup.2 and an elongation at break of about 30 to 50% in the transverse direction of the web. The breaking strength in the transverse direction of the web is equal to or greater than that in the longitudinal direction of the web. On its entire surface facing the film strip, the tubular casing has a substantially gas-impermeable and sealable layer, as has the film strip on the surface which comes into contact with the tubular casing.Type: GrantFiled: May 26, 1983Date of Patent: January 7, 1986Assignee: Hoechst AktiengesellschaftInventors: Herbert Porrmann, Walter Seifried, Ludwig Klenk, Karl Stenger

Patent number: 4563376Abstract: Disclosed is a tubular food casing which comprises a support tubing of cellulose hydrate comprising water and from about 15 to 30% by weight of a plasticizer and a coating layer applied to the inside surface of the tubing, which comprises a water-insoluble, cured cationic resin, especially a resin based on protein formaldehyde, urea formaldehyde or melamine formaldehyde or a condensation product of an aliphatic polyamine or polyamide or a polyamine-polyamide with bifunctional halohydrins or the derivatives thereof, such as epichlorohydrin, or mixtures of these resins, and additionally a natural oil, a synthetic triglyceride mixture with vegetable fatty acids having from 4 to 14 carbon atoms in their carbon chain, a paraffin oil and/or a silicone oil and optionally one or more than one emulsifier for the oil. Also disclosed is a process for the manufacture of the tubing and a use of the tubing as an artificial sausage casing.Type: GrantFiled: March 1, 1983Date of Patent: January 7, 1986Assignee: Hoechst AktiengesellschaftInventors: Klaus-Dieter Hammer, Erwin Kindl, Heinz Luchterhand, Hermann Winter

Patent number: H35Abstract: This invention provides a method of producing dehydrated meat products wh more easily and completely rehydrate than prior art dehydrated meats. This is accomplished by expansion of the cooked meat matrix by the addition of water, salt, phosphate and adjunctive hydrophilic ingredients prior to cooking. This invention is intended for use with formed meats consisting of a combination of chunked, flaked and ground or emulsified meats. The use of a gas and moisture impermeable casing for cooking the meat allows the meat to be fully cooked without concurrent losses in either weight or volume, thus preventing density increase prior to dehydration.Type: GrantFiled: October 29, 1984Date of Patent: March 4, 1986Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Daniel Berkowitz
