  • Patent number: 5084283
    Abstract: A cellulosic casing for making skinless frankfurters has distinguishing indicia such as a pattern of grill marks on one surface of the casing. The indicia is formed by printing, for example with caramel, onto the casing surface. The caramel remains on the casing surface and is nondiffusible into the casing. During the stuffing and processing of a food product in the casing, the indicia bearing casing surface is in contact with the food product so the indicia releases and indelibly transfers to the contiguous surface of the food casing. The method of making the casing article, stuffing it and the resulting indicia bearing food product are also disclosed.

  • Patent number: 4997663
    Abstract: Parboil or raw "skinless" sausages are prepared using a reusable tubular casing formed from a lipophilic, relatively nonpolar material in a process wherein the casing is filled with uncoagulated sausage material containing protein and fat (lipids) and initially heated to a relatively high temperature for a short period of time (e.g. about 175.degree.-250.degree. C. for 2-3 minutes) to preferentially coagulate only the protein material immediately adjacent the casing to form a relatively thin (e.g. less than about 1 mm) cohesive, "skin-like" layer. The sausage is then removed, such as by ejection, for further processing, such as smoking, drying, reddening and final coagulation with the "skin-like" layer providing sufficient support for the subsequent processing of the substantially uncoagulated ejected sausage material, and the casing is simply rinsed and refilled.

  • Patent number: 4604309
    Abstract: The invention relates to the solvent extraction of smoke colorant from natural liquid smoke. In accordance with the invention, the known acidic liquid smokes which are formed by contacting burning wood smoke with water are neutralized to separate tarry materials and form neutral storage stable liquid colorants which are capable of passing through regenerated cellulose sausage casings during cooking to color the meat and further do not cause deterioration of the casing during storage.

  • Patent number: 4601929
    Abstract: The present invention relates to a tubular film used for packing foodstuffs in paste form, this tubular film being of polyamide that can absorb at least 5% water, and which at an internal pressure between 0 and 0.6 bar permits substantially reversible deformation and which has a matt appearance. The present invention also relates to a process for the production of this tubular film by multiaxial stretching of the primary tube with stretch ratios of at least 1:2.3 in the longitudinal direction and at least 1:2.5 in the transverse direction, and total thermal fixing of the stretched tube during controlled shrinkage. In addition, the invention describes a boiled or cooked sausage as well as a soft cheese, these being packed in a tubular film according to the invention.

  • Patent number: 4594251
    Abstract: Tar-depleted liquid smoke solutions are made by generating a smoke vapor, selectively solvent extracting the tars from the smoke vapor, and absorbing the color, flavor and odor constituents of the smoke vapors into an aqueous medium. The aqueous tar-depleted liquid smoke has a high coloring ability, a high concentration of carbonyls, and a low phenol content and is used to treat a tubular casing.

  • Patent number: 4590107
    Abstract: A regenerated cellulose sausage casing and process for its manufacture is disclosed, which casing has a basis weight, wall thickness and plasticizer content substantially lower, and skin content substantially higher, than that of casing products produced in the normal manner by the viscose process but has sufficient strength and flexibility characteristics to undergo high speed commercial shirring and meat stuffing operations with a minimum of breakage and pinholing.

  • Patent number: 4563376
    Abstract: 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.

  • Patent number: 4563231
    Abstract: 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.

  • Patent number: 4562101
    Abstract: Disclosed is a shirred sausage casing of a web film in the form of a tubing which comprises a seam region, formed from the edge regions of the web film, which extends in a helically twisted manner about the longitudinal axis of the casing in a manner wherein more than 10 helical turns are present in a 10 m length of the casing. Also disclosed is a process for producing a casing of this type.

  • Patent number: H35
    Abstract: 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.
