  • Publication number: 20020004088
    Abstract: The invention relates to a tubular food casing, one surface of which has a continuous layer which is solid under standard conditions of temperature and pressure, prepared from a mixture made from a wax solid under these conditions and/or from a wax-like component, from a liquid smoke, and from an emulsifier with the aid of which a stable water-in-oil emulsion can be formed. The layer adheres firmly to the casing and is also flexible, so that the outer side of the casing can be turned inside out without difficulty. When the sausages produced therewith are cooked or scalded, the wax or the wax-like component melts so that the liquid smoke can migrate onto the surface of the meat emulsion and there produce the desired characteristics of smoking.

  • Patent number: 6132779
    Abstract: The removal of a cellulosic casing from about a sausage, stuffed and processed in the casing, is accomplished by contacting the casing, either before or after stuffing, with a food grade enzyme, e.g.a. cellulase or cellulase enzyme complex, to metabolize the cellulosic casing on the sausage thereby producing a substantially casing-free sausage. Contacting the casing with the enzyme is accomplished prior to stuffing by applying an enzyme solution to the internal surface of the casing as part of an internal shirring spray or as a stripe to the exterior of the casing. Contacting with the enzyme after stuffing is accomplished by showering the stuffed casing with the enzyme solution. Also disclosed is the use of a combination of pre and post stuffing methods for applying the enzyme to the casing.

  • Patent number: 5262211
    Abstract: A tubular foodstuff casing, in particular synthetic sausage casing, based on cellulose contains a di-n-didecyl-dimethylammonium compound as a fungicidal agent, which is optionally used in admixture with salts of sorbic acid, fungicidal heterocyclic compounds, such as an isothiazolone compound, or glycerol monolaurate. The coating prevents mold attack on the casing.

  • Patent number: 5236726
    Abstract: A method of processing cellulose sausage skins is disclosed in which sausage skins are filled with contents to make sausages, the cellulose sausage skins are removed from the sausages, the removed sausage skins are dissolved to form a recycled cellulose dope, and new sausage skins are formed from the recycled cellulose dope. Dissolving sausage skins under soda cellulose Q condition for subsequent reuse is specifically described. In addition, forming a dissolved cellulose feed stock for use in producing sausage skins employing cavitation and a solvent is disclosed.

  • Patent number: 5229506
    Abstract: 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.

  • Patent number: 5215125
    Abstract: 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.
