  • Patent number: 6899907
    Abstract: A method of bleaching bran, comprising treating bran with a hydrogen peroxide solution to produce lightened bran having fewer native flavor components is disclosed. In one embodiment, a bleached bran product suitable for admixing with whole wheat flour to produce white whole wheat flour having an ā€œLā€ value on the Hunter scale of at least about 75 is disclosed. In one embodiment, cleaned bran is treated with a solution of chelating agents to remove or inactivate transition metals. Thereafter, exposure to oxidant substances, such as hydrogen peroxide, ozone, and so forth, in the presence of an alkaline compound produces bleached bran, which can be washed and dried for use in products such as flours, pastas, and so forth.

  • Patent number: 6887509
    Abstract: A method of milling grain, comprising, prior to milling, heating a quantity of grain kernels to at least a glass transition onset temperature to form heated softened grain kernels is disclosed. With this method, it has surprisingly been found that moisture tempering, in most instances, is no longer required as a conditioning step for milling. Depending on the temperature to which the grain is heated, the texture of the grain kernel can be moved to a variety of textures, including, but not limited to, a more leathery or rubbery texture. In an alternative embodiment, the heat tempering step is preceded by a moisture tempering step. The method increases overall yield and improves control of the milling process.

  • Publication number: 20030108652
    Abstract: A method of bleaching bran, comprising treating bran with a hydrogen peroxide solution to produce lightened bran having fewer native flavor components is disclosed. In one embodiment, a bleached bran product suitable for admixing with whole wheat flour to produce white whole wheat flour having an “L” value on the Hunter scale of at least about 75 is disclosed. In one embodiment, cleaned bran is treated with a solution of chelating agents to remove or inactivate transition metals. Thereafter, exposure to oxidant substances, such as hydrogen peroxide, ozone, and so forth, in the presence of an alkaline compound produces bleached bran, which can be washed and dried for use in products such as flours, pastas, and so forth.

  • Patent number: 6036115
    Abstract: An improved sugar slurry spray discharge nozzle (10) is shown for co-spraying steam into the sugar slurry spray. The nozzle (10) finds particular suitability for use in the applying of a sugar coating solution or slurry to a Ready-To-Eat breakfast cereal base in an enrober. By virtue of providing a steam assist to the spraying of the sticky sugar coating solution, desirable reductions in downtime for cleaning of the enrober are achieved. The improved nozzle includes a cylindrical steam chamber (14), an axially extending slurry supply tube (22) disposed therein having a discharge port (25) and orifice for discharging steam into the slurry discharge such as opposed pair of arcuate steam discharge slits (66, 68) proximate the slurry tube discharge port (25). The steam discharge atomizes the slurry discharge spray and provides heat energy to the spray with the result that the slurry is applied to the cereal base with reduced sugar build-up on the enrober.

  • Patent number: 5968572
    Abstract: An enrober (100) for applying a topical coating to an exterior surface of multiple pieces of a food base is disclosed having a marked decrease in the amount of build-up upon the internal surface of the drum (102) allowing for reductions in cleaning service requirements and its concomitant losses in production capacity and for reductions in undesirable product agglomerates. In the preferred form, the drum (102) is formed by a thin wall in a generally cylindrical shape and formed of hydrophobic material in the form of high-density polyethylene having low-stick characteristics with the topically coated food base. Moisture, in addition to any present in the topical coating, is added to the drum (102) to prevent or practically eliminate build-up on the drum (102). The topical coating in the form of a slurry can be co-sprayed with steam in an atomized intermixed spray onto the food base by a nozzle (10, 80).

  • Patent number: 4857353
    Abstract: Disclosed are dry culinary mixes for use in preparing baked goods, especially microwave layer cakes. The dry mixes employ high levels of a defined nucleating agent(s). The dry mixes enable the consumer to bake a cake using microwave radiant energy comparable to a conventionally oven baked cake in quality, structure, volume, and texture. The nucleating agent can be any water insoluble minute material having a particle size of 20-200 microns. Preferred nucleating agents are particularly sized microcrystalline cellulose particles.
