  • Patent number: 6309686
    Abstract: A process for making an aerated, confectionery product of multiple colors includes, as a first step, preparing a slurry of water, sugar, and gelatin. The slurry is divided into at least first and second portions or batches having a defined color to provide a second color. A dye or colorant of a color is added to the second portion or batch to provide a second color. Each of the first and second batches are then individually aerated to form first and second aerated streams of first and second colors of substantially identical density and rheological properties. After aeration of the first and second portions, the first and second colored streams are fed to an extrusion die manifold, where they are extruded in disproportionate amounts to form a multicolored a rope having the first and second colors of unequal proportion. A starch anti-sticking agent is applied, and the rope is cut into individual pieces. The individual pieces are then dried to a 1 to 5% moisture content.

  • Patent number: 6251452
    Abstract: Apparatus (10) and methods are disclosed where plastic extrudable food product is provided such as by an extruder or pump and is combined with another food product without intermixing to form a complexly patterned food product, such as by a pattern forming die (20). The cross-sectional area of the patterned food product is reduced from an inlet end (34) to an outlet end (36) by a factor of 4:1 to as much as 50:1 at an average convergence angle of 5 to 65° while maintaining the cross-sectional pattern to form a reduced cross-sectional patterned food product, and then is extruded through a die port having an opening equal to the reduced cross-sectional area to form a complexly patterned extrudate.

  • Patent number: 6207216
    Abstract: Aerated confections that dissolve quickly in water or in a dairy beverage are disclosed. The aerated food products preferably include 50 to 98% of a saccharide component; about 0.5 to 30% of a structuring agent; about 1 to 6% moisture; and about 1% to 5% of a whipping agent. The aerated food products have a density of about 0.1 to 1.0 g/cc. The compositions can be formed into pieces ranging from about 0.1 to 5 g each. Preparation methods for the pieces are also disclosed. The confectionery food products find particular suitability for use as ingredients for children's RTE cereals.

  • Patent number: 6197355
    Abstract: A method for processing at least one rope of aerated confectionery foam. The method includes extruding at least one rope of aerated confectionery foam from an extruder. The rope is conveyed from the extruder to a rotary cutter. An anti-sticking agent, such as powdered starch, is applied to the rope as the rope is conveyed from the extruder to the rotary cutter. Finally, the rope is cut into pieces with the rotary cutter. In one preferred embodiment, the rotary cutter is operated to perform at least 5,000 cuts per minute.

  • Patent number: 6180158
    Abstract: A continuous method for preparing an aerated confection, especially marshmallows, includes the steps of A. continuously forming a clear concentrated sugar syrup in a single vessel by continuously admixing to form a sugar syrup slurry; cooking the sugar syrup slurry with agitation and indirect heat to dissolve the solids, concentrating the sugar syrup by evaporating water as vapor and venting the vapor to form a concentrated clear syrup, wherein the residence time of the syrup within the vessel ranges from about 1 to 5 minutes; B. cooling the clear concentrated syrup without crystallization to form a cooled clear sugar syrup; C. admixing the clear cooled sugar syrup with about 1 to 30% of a foam structuring agent to form a liquid confection blend; D. seeding the liquid confection blend with dry sugar crystals to form a seeded liquid confection blend; E. aerating the seeded liquid confection blend to form an aerated confection plastic foam; F.

  • Patent number: 5776534
    Abstract: An apparatus (10) for forming a single extrudable food stream such as a cooked cereal dough into a plurality of differently colored and/or flavored dough streams is disclosed including an extruder having screw augers in a main passageway for advancing a plastic food mass, a device for dividing the plastic food mass into a plurality of substreams such as a branching passageway section in fluid communication with a plurality of sub-divided dough passageways, and a die head having a plurality of die ports for each subpassageway. Each subpassageway has a separate conduit for supplying an additive and has disposed therein a multiplicity of in-line static mixer elements to admix the additive into the substreams of the plastic food mass before passage through the die ports.
