  • 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: 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: 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: 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: 4555408
    Abstract: An artificial sausage casing of two-dimensional fiber material, in particular a knitted or woven fabric, is impregnated, at least on the inside, with fat in order to extend the maturing time of the sausage. To obtain good adhesion to the surface of encased sausage meat the inside of the casing surface is provided with a pile consisting of stiff fibers and/or filaments which are positively anchored in the surface of the sausage meat.

  • Patent number: 4550025
    Abstract: A packaging film which is permeable to smoke constituents is made from a thermoplastic copolyester. The copolyester is built up of recurrent long-chain and short-chain ester units which are joined head-to-tail through ester bonds, the long-chain ester units corresponding to the formula ##STR1## and the short-chain ester units to the formula: ##STR2## where R.sub.1 is a divalent radical remaining after removal of the terminal hydroxyl groups from a poly(alkylene oxide) glycol having a molecular weight in the range of 600 to 6000 and a carbon to oxygen ratio of 2.0 to 2.7; R.sub.2 is a divalent radical remaining after removal of the hydroxyl groups from a diol having a molecular weight not higher than 250; R.sub.3 is a divalent radical remaining after removal of the carboxylic acid groups from a dicarboxylic acid. Said long-chain ester units amount to 20 to 60% by weight of the copolyester and at least 70% of the R.sub.3 groups are 1,4-phenylene radicals. The phenol number of the film, expressed in mg per m.

  • Patent number: 4550042
    Abstract: Disclosed is a shirred sausage casing comprising a tubular casing having an area of increased thickness, e.g., a glued seam, running in the direction of its longitudinal axis. This area of increased thickness is helically arranged and extends transversely to the helical windings of the main-fold constituting the outside of the shirred sausage casing. The area of increased thickness is displaced by its width, between two contiguous windings of the main-fold. Also disclosed is a process for manufacturing a casing of this type.

  • Patent number: 4546023
    Abstract: Disclosed is a smoke-permeable film suitable for the production of tubular casings, especially sausage casings, including a film of fiber-reinforced regenerated cellulose and a layer of thermoplastic sealable resin containing a vinylidene group-containing copolymer. The thermoplastic sealable resin has a smoke-permeable structure, including linear discontinuities running parallel to one another, and is anchored to the surface of the cellulose film with the aid of an adhesion promoting layer. The resin layer completely coats at least one of two surfaces of the cellulose film. Also disclosed is a casing made of the smoke-permeable film and a method for producing the film.

  • 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.
