A tubular film sausage casing comprising a cellulose aminomethanate wherein from 0.5 to 30 numerical percent of the cellulose hydroxy groups have been substituted with aminomethanate groups. The casing may be crosslinked or may be fiber reinforced.

Cellulose aminomethanate sausage casings

An improvement to the process for synthesizing cellulose aminomethanate is disclosed which comprises slurring cellulose in low concentrations of aqueous caustic solutions, in the presence of urea, and steeping the slurried mixture, at from about 2.degree. C. to about -15.degree. C., for a time sufficient to permit swelling of the cellulose and uniform distribution of the urea. Cellulose aminomethanate manufactured from product prepared in accord with this process, has a uniform distribution of aminomethanate throughout the cellulose at the molecular level and comprises a suitable product for manufacturing sausage casing.

Preparation of cellulose aminomethanate

A cellulose fiber mat sized with cellulose aminomethanate. The fiber mat is desirably an abaca fiber mat and the mat may be used as a reinforcement in products such as food casings, e.g., a sausage casing. Such a food casing comprises such a sized mat impregnated with additional cured resinous material. Such additional resinous material is desirably a cured viscose such as xanthate or cellulose aminomethanate viscose.

This invention relates to an improvement to a process for synthesizing cellulose aminomethanate which comprises slurrying cellulose in an aqueous caustic solution, in the presence of urea; steeping the slurried mixture for a time sufficient to permit swelling of the cellulose for uniform distribution of the urea; concentrating the steeped mixture and treating an extraction of the concentrate with an ion-exchanger. When cellulose aminomethanate is manufactured from product prepared in accord with this process, it has a uniform distribution of substituent throughout the cellulose at the molecular level and comprises a suitable product for manufacturing sausage casing.

Cellulose aminomethanate by ion-exchange extraction

Polydextrose compound containing anti-pleat lock coatings, food casings containing said coatings, and a method for their production which comprises applying to the surface thereof an aqueous coating composition containing a polydextrose compound are disclosed. The coated food casings exhibit improved food release characteristics, improved resistance to strand breakage, and improved anti-pleat lock characteristics.

Polydextrose compounds as anti-pleat lock additives for cellulose

A polymeric compound comprising crosslinked cellulose aminomethanate wherein 0.5 to 30 numerical percent of the cellulose hydroxy groups have been substituted with aminomethanate groups, each of the crosslinks being formed by a crosslinking agent reacted to connect at least two of the cellulose hydroxy groups, at least two of the aminomethanate groups or at least one each of the hydroxy groups and aminomethanate groups.

Crosslinked cellulose aminomethanate

A reinforced article comprising cellulose aminomethanate containing a reinforcing fiber, wherein 0.5 to 30 numerical percent of the cellulose hydroxy groups have been substituted with aminomethanate groups.

Reinforced cellulose aminomethanate

A method for seaming flexible cellulose webs, to form a flexible cellulosic laminate structure, by a process which comprises overlapping edges of said cellulosic web, applying therebetween an aqueous zinc chloride solution, heating and pressing together the overlapped edges and retaining at least about 0.002 g/cm.sup.2 or more zinc chloride at the seam of said web and the reuslting seamed webs.

Process for seaming coated cellulose webs

Packaged fibrous and non-fibrous reinforced food casings containing sufficient water that presoaking prior to stuffing can be eliminated. The casings which rely on water as the sole or principal plasticizer do not rely on chemical type plasticizers like glycerin and propylene glycol. The premoisturized, ready-to-stuff casings are preserved with effective amounts of a high pH active antimycotic agent. Drying requirements can be reduced or eliminated.

Method for making preserved, high moisture, ready-to-stuff food casings

Amylose and high amylose starch fibrous food wrappings, including casings for meat products provide a low cost alternative to ordinary fibrous casings. The composite material consists of a cross-linked matrix of the amylose polymer coupled or bonded with the reinforcement and possesses a wet strength and elongation properties for suitable handling and stuffing without exhibiting embrittlement upon aging.

Non-edible, reinforced amylose and amylose starch food casings

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.

Thin-walled, low plasticized content regenerated cellulose sausage casing

This invention relates to Arabinogalactan containing release coatings, Arabinogalactan coated food casings and a method for their production, which comprises applying to the food containing surface thereof an aqueous coating composition containing less than 3 percent by weight Arabinogalactan. The coated food casings exhibit improved food release characteristics, improved resistance to strand breakage and improved anti-pleat lock characteristics.

Arabinogalactans as release additives for cellulose containing casings

Highly elastic films, filaments, and shaped articles can be prepared from amylose by forming a dispersion or solution of amylose in an appropriate liquid vehicle under conditions in which the molecular conformation of amylose is substantially helical, then forming a shaped article, film, or filament from the dispersion or solution and finally crosslinking the amylose with a crosslinking agent, the crosslinking agent being present in a proportion for providing an average of about 1 crosslink per 500 amylose monomer units to about 1 crosslink per 10 amylose monomer units.

Elastic amylose polymers

This invention relates to an artificial sausage casing of regenerated cellulose having a coating composition applied over the internal surface thereof which exhibits excellent meat release from sausages processed therein under high speed mechanical peeling and has improved resistance to strand breakage and pinholing during shirring and meat processing, the coating being an admixture of a water-soluble cellulose ether, a partial fatty acid ester of sorbitan or mannitan and a water-soluble polyalkylene glycol ether having the formula RO(--C.sub.2 H.sub.4 O).sub.n --H wherein R represents long chain alkyl radicals having 8 to 16 carbon atoms and n is an integer from 4 to 40.
