Abstract: A process for manufacturing a tubular film such as an edible casing film or a packaging film. The process includes the steps of providing a preblended powder composition containing a polymer matrix, a plasticizer, and water; feeding the preblended powder composition to an extruder; heating the preblended powder composition to a temperature above 100 degrees Celsius for a sufficient time to fully hydrate the polymer matrix and to convert the powder composition to a flowable mass; and extruding the flowable mass through a tubular die of the extruder to form the tubular film. The tubular film comprises: about 40-75 wt % polymer matrix; about 10-35 wt % plasticizer; and about 10-35 wt % water. The polymer matrix component is fully hydrated under the temperature, pressure and shear conditions inside the extruder, and may have a component which is only fully hydrated at temperatures above about 100 degrees Celsius.

Abstract: Tubular sausage casings can be prepared from non-animal materials, primarily starches and flours by film-casting followed by gluing with an edible glue composed of konjac and carrageenan. In this way, it has been made possible to prepare non-animal meat casings commercially, that can be used with conventional sausage production technology.

Abstract: Novel film compositions are described for use in the processing of meat products, particularly as sausage casings and wrappers for hams and other cured meat products. By combining gelatin and other hydrocolloid film forming polymer materials, edible film compositions are achieved by solution casting which exhibit superior and desirable properties for adhering to the meat product and presenting a shining, appealing surface.

Abstract: Orally disintegrating or dissolving edible strips for use as a matrix for retaining and delivering nutrients, flavors and medicinal compounds are made from new liquid film casting compositions comprising a major proportion of gelatin. The particularly low melting range for hydrated gelatin produces films that leave virtually no residue upon dissolving in the mouth and can be used in the form of thicker films and strips than known edible films.

Abstract: Film-form soap compositions for hand washing or other personal hygienic uses are described in which hydroxypropyl methyl cellulose polymer is admixed with sodium isothionate surfactant to provide compositions having superior properties of strength, rapid dissolution in water and good foaming properties.

Abstract: Non-edible meat processing and packaging films made of polyvinyl alcohol (PVA) instead of conventional cellulose have been found to produce films which exhibit enhanced strength and tear resistance, permeability to added smoke and other flavors, as well as additional properties useful in commercial meat processing operations. Either partially or fully hydrolyzed PVA is used, depending on whether the film is intended to remain insoluble or to dissolve off the meat product during the cooking process. A liquid composition for casting or extrusion of films according to the invention will combine PVA, water, a plasticizer and suitable hydrocolloids to act as modifying agents for processing of the film.

Abstract: Edible films incorporated carrageenan in conjunction with insoluble and inert carbohydrate components, such as high-amylose starch, have been found to exhibit superior properties as material for meat casings, including high strength and excellent adhesion to the meat. Liquid compositions for casting into such edible films are disclosed which facilitate the efficient production of sausage and other film-encased meat products using conventional forming apparatus.

Abstract: Rapidly water soluble strips of film carrying surfactants are described for application as soaps and detergents. A preferred water soluble polymer base for the film compositions comprises a carbohydrate based hydrocolloid such as hydroxy propyl methyl cellulose or sodium carboxymethyl cellulose. Suitable base polymers are quick dissolving and can carry high polymer loadings and leave virtually no residue upon rapid dissolution in water. The addition of a small amount of plasticizer to the composition imparts the degree of flexibility required for practical applications.

Abstract: Edible films incorporating carrageenan in conjunction with Konjac and/or Gellan gums have been prepared as substitutes for edible collagen film currently used in meat processing. Compositions according to the present invention overcome the inherent thermoreversibility of carrageenan gel and do not disintegrate from exposure to hot or boiling water. The film can readily be processed to form casing, bags or other packaging useful in the food industry.
