  • Patent number: 6589328
    Abstract: The invention provides sponges (foams) produced from hydrocolloids by the expansion of gels of these. The foams have properties which can be varied, such as water absorption, biodegradibility, pore size and structure. Edible products can be produced which may contain an edible plasticizer, a sugar or sugar substitute and possibly also a flavoring agent or taste enhancer. The novel sponges are produced by preparing a gel of a hydrocolloid, and either sealing it in a closed vessel with a liquid of similar composition, pressurizing the vessel and abruptly releasing the pressure, followed by freeze drying, or by incorporating in such a gel a suitable microorganism, such as a yeast and inducing fermentation in the presence of a suitable nutrient medium, so that the carbon dioxide formed results in the expansion and foam formation, which is processed to the final product. The sponges-foams of the invention are such, that the initial network of the gel is maintained.

  • Patent number: 5186902
    Abstract: A CO.sub.2 gas generator for a utilization device is located in a housing and chemically generates CO.sub.2 from a chemical reaction between two reagents contained within a common container. The reagents are located in different chambers of the container with a CO.sub.2 accumulation region being included in one of the chambers. A reference pressure source of a predetermined pressure forces the two reagents into contact with each other when the pressure of gas in the CO.sub.2 accumulation region is less than the predetermined pressure whereupon CO.sub.2 is generated in one of the chambers. An output conduit in fluid communication with the CO.sub.2 accumulation region is provided to withdraw the generated gas from the generator. As the CO.sub.2 is withdrawn, the gas pressure drops permitting more mixing of the reagents. When the CO.sub.2 pressure becomes equal to or higher than the predetermined pressure applied by the reference pressure source, the reagents become separate again and gas generation ceases.

    Abstract: An encrusted food product, such as a pizza roll, is prepared by co-extruding a cavity-forming sealant material, such as cheese, with a bread or pastry dough whereby the cavity-forming sealant material is encapsulated in the dough, subjecting the co-extruded article to a preliminary baking whereby the cavity-forming sealant material melts and generates gases. The molten material coats the interior of the encapsulating dough and the generated gases cause expansion of the space occupied originally by the cavity-forming sealant material thus creating a cavity or void within the dough. After preliminary baking the dough with its interior void lined and sealed with molten material is chilled to set the molten material. Thereafter the void or cavity of the dough so prepared can be filled with any desired filling and baking can be completed.

  • Patent number: 4316409
    Abstract: A closed pressurized container for producing a carbonated beverage of superior quality by providing for contact therein of water and a solid carbonation source. The pressurized container is designed to withstand the pressures and temperatures generated during the preparation of a carbonated beverage from a solid carbonation source. In a preferred embodiment, the container is a rigid receptacle in the shape of a wide mouth bottle adapted to receive a large cap or cover. A perforated basket is mounted inside the cover, and is accessible to water in the bottle when that vessel is turned upside down to an inverted position. A spring loaded, manually operated valve is provided in the cover to permit venting of carbon dioxide from the interior thereof after the water-based mixture within the container has become sufficiently carbonated by absorbing carbon dioxide released by contact of water with the solid carbonation source.

  • Patent number: 4310560
    Abstract: A method of producing a porous pelletized food product.A mixture of finely divided, particulate edible materials, including at least one material which acquires surface stickiness when moistened and a chemical leavening system is contacted with a spray of water and formed into pellets on a pelletizing disc. The moist pellets are contacted with a stream of hot air to effect reaction of the components of the leavening system with the release of carbon dioxide gas to provide the pellets with a porous cellular structure, and to dry the pellets. The resulting dried pellets have a crisp, crunchy, friable texture, and sufficient mechanical strength to permit the pellets to be compacted at a pressure of 500-750 psi without crumbling or disintegration of the pellets. If desired, the pellets may be coated with an edible fat having a relatively high melting point to produce porous, non-hydrating food pellets.

  • Patent number: 4186215
    Abstract: An arrangement for carbonating a beverage over an extended period of time through the addition of water or beverage liquid base to a powdered or dry carbonate and acid located in a pressure chamber. A permeable surface of the chamber allows a small quantity of water to enter and initiate a chemical reaction generating gaseous carbon dioxide. The carbon dioxide will exit the chamber and carbonate the beverage. A resultant pressure drop in the chamber will permit the entry of more water to generate more carbon dioxide until the pressure is balanced, with the sequence being repetitive. A flavoring chamber containing flavor powder may be superimposed on the pressure chamber to effect admixing of the flavoring and liquid concurrent with carbonation. The pressure chamber, and flavoring chamber, may be formed integrally with a container, or may consist of a separate unit adapted to be placed in a container to which water or liquid base is then added.
