The modified starch dusting powders are free flowing and are characterized by a protein content of less than about 0.15% by weight, hydroxyl groups oxidized to a level of from about 0.5 to about 0.05% by weight and a degree of cross-linking of other hydroxyl groups characterized by bound phosphorus levels of from about 200 to about 1200 ppm.

  • Patent number: 5089607
    Abstract: The residual flow of the starch preparation from wheat, rye, oats or barley is thickened to a dry material content of 17 to 25 weight % after which an enzyme preparation with pentosanase activity, originating from fungi or yeasts, is added. The enzyme preparation is allowed to react for 0.5 to 4 hours with a pH of 2.6 to 3.7 and at a temperature between 30 and 50.degree. C. and the starch fraction is separated afterward with an increased yield. The starch thus obtained is a calibrated, fine grained starch of which at least 90 weight % of the grains have a diameter of 3 to 12 micrometer.

  • Patent number: 5057157
    Abstract: A process for the preparation of granular cold water swelling/soluble starches by alcoholic-alkali treatments is disclosed which comprises contacting a quantity of starch granules with respective quantities of an alcohol and a strong base to swell the granules and convert the starch to form having increased cold water solubility. The process can be used on waxy, high amylose, tuber, and normal starches. The resulting cold water swelling/soluble starch preferably exhibits about 50% to 94% solubility in cold water.

  • Patent number: 4973447
    Abstract: Improved dual modified waxy barley starch products are provided which exhibit excellent freeze-thaw stability and other properties making the starches eminently suited for incorporation into food products such as pie fillings or the like. Separated waxy barley starch is subjected to sequential hydroxypropylation (at a level to provide at least about thre percent by weight hydroxypropyl groups) and cross-linking (phosphorus oxychloride or sodium trimetaphosphate) to provide the products of the invention.

  • Patent number: 4923976
    Abstract: Surface active glycosides are made by reaction of monose or polyose with an alcohol in the presence of an acid catalyst composition containing acid catalyst and reducing agent; the color properties of the glycosodes so made makes them attractive for use in cosmetic, pharmaceutical and household products. Suitable reducing agents include phosphorous, hypophosphorous, sulphurous, hyposulphurous, nitrous and hyponitrous acids. Suitable catalysts include the known etherification catalysts.

  • Patent number: 4839060
    Abstract: Modified starch compositions and their use for flocculating mineral waste residues, particularly the red mud containing alumina liquors from bauxite residues, comprising the addition to an alumina liquor of a flocculating amount of a methylated starch which, optionally, may be hydrolyzed, or a methylated starch which is also sulfonated and, optionally, may be hydrolyzed. Preferably, the methylated starch compositions are potato and dasheen starch derivatives prepared at temperatures of about 50.degree. to about 85.degree. C.

  • Patent number: 4838944
    Abstract: A process for the degradation of granular starch employing hydrogen peroxide and a catalytic amount of manganese ions in an alkaline slurry reaction is disclosed. The manganese ions catalyze the degradative reaction so that the desired amount of degradation of the granular starch can be brought about in a shorter reaction period as opposed to a reaction run without manganese ions.

  • Patent number: 4810307
    Abstract: A method for improving the properties of particles of a starch hydrolyzate product made by the partial hydrolysis of cereal and root based starches. Particles of starting material are blended with a volatile liquid other than water, and the resulting blend is compacted in a roller compactor without extraneous lubricant, to form a sheet. The sheet is broken into small particles which are sieved and dried. The resulting particles are non-spherical, appear crystalline under a light microscope and have a surface topography comprising cracks, crevices and fissures. These particles have good solubility, a bulk density comparable to the starting material, and no flow or dusting problems.

  • Patent number: 4792362
    Abstract: The invention relates to a process for the production of low-viscosity, aqueous dispersions of gelatinized, starches, and to dispersions produced thereby. The viscosity is considerably reduced by adding a nonionic tenside from the group of unilaterally etherified polyoxyalkylene glycols, so that up to 50% strength, stirrable dispersions of gelatinized starch can be produced.
