  • Publication number: 20020197373
    Abstract: This invention relates to a process for preparing cereal grain having increased dietary fiber and/or resistant starch content and the process tolerant grain prepared thereby. Further, this invention provides high amylose grain with unusually high dietary fiber and resistant starch content. In particular, this invention involves the preparation of the improved grain by a combination of moisture and temperature conditions and further to use of the grain in the preparation of products containing starch.

  • Patent number: 6096524
    Abstract: High solids maltodextrin syrups, some of which are useful as the base for remoistenable adhesives, are prepared by a high solids alpha amylase enzyme conversion process. They are characterized by their high solids content (at least 55 wt. %) and light color. A granular chemically derivatized, optionally converted, starch having a degree of substitution of greater than about 0.01 and less than about 0.5 is used as the starting material. The maltodextrins have a reducing sugar content of about 5-19 dextrose equivalent and a distinct polymodal molecular weight distribution. When a granular highly esterified starch (D.S. of 0.5-1.8) is used as the starting material in the high solids process, the resulting enzyme-converted, esterified maltodextrins are characterized by their improved water dispersibility.

  • Patent number: 6054302
    Abstract: A high solids, enzyme conversion process for preparing an enzyme-converted starch is carried out by adding to a modified or unmodified starch, preferably a granular starch, water and an enzyme in an amount sufficient to produce a single phase powdered mixture without a visible free water phase. The enzyme is activated by heating while maintaining a substantially constant moisture content in the mixture. The enzyme converted starch is recovered as a syrup, a granular converted starch, or mixtures thereof, or as a powder obtained by drying the syrup.

  • Patent number: 5932639
    Abstract: The present invention is directed to remoistenable and non-remoistenable adhesives which contain at least about 50 wt % of a maltodextrin syrup having a reducing sugar content of about 5-19 dextrose equivalent and solids content of about 60-80 % water, and an effective amount of other conventional adhesive additives. When the adhesive is a remoistenable adhesive, a chemically derivatized starch having an amylose content of 40 % or less and a D.S. of about 0.01 to less than about 0.50 is used. A preferred remoistenable adhesive also contains polyvinyl acetate and/or ethylene vinyl acetate in an amount from about 15-90 wt. % The maltodextrin syrup is prepared from a converted or a non-converted, chemically derivatized or underivatized granular starch, by a high solids, single phase enzyme conversion process. When derivatized, the maltodextrin has (i) substituents in an amount sufficient to provide a degree of substitution between greater than about 0.01 and less than about 0.50.

  • Patent number: 5902410
    Abstract: A resistant granular starch with high dietary fiber content and the method of preparing this product wherein a high amylose starch having at least 40% by weight amylose content and total moisture content of from about 10 to 90% by weight, based on the weight of starch and water is heated in the presence of a starch swelling inhibiting agent, particularly an inorganic salt, to a temperature of from about 60 to 160.degree. C. to provide a granular starch which retains its granular structure and has a total dietary fiber content of at least 12%.

  • Patent number: 5688845
    Abstract: The present invention is directed to a high solids, water-based remoistenable adhesive consisting essentially of at least about 50% to less than 100% of a maltodextrin syrup having a solids content of about 60-80%, 0 to about 50% of water, and an effective amount of a preservative. The maltodextrin syrup is prepared from a converted or a non-converted, chemically derivatized granular starch having an amylose content of 40% or less, by a high solids, single phase enzyme conversion process. The maltodextrin has (i) substituents in an amount sufficient to provide a degree of substitution between greater than about 0.01 and less than about 0.50; (ii) a reducing sugar content of about 5-19 dextrose equivalent; and (iii) a polymodal molecular weight distribution having one peak between about 630-1600 daltons and at least one other peak between about 1600-2,500,000 daltons.
