  • Patent number: 6613898
    Abstract: Disclosed are a method for the reduction of an oligosaccharide mixture and an oligosaccharide mixture prepared thereby. In accordance with the disclosed invention, a mixture of oligosaccharides having a given DP profile is reduced to a DE of essentially zero by catalytically hydrogenating the mixture under reaction conditions sufficient to preserve the DP profile of the mixture, which reaction conditions typically include a reaction temperature ranging from about 50° C. to about 150° C. and a reaction pressure ranging up to about 1500 psi. Surprisingly, when the mixture is a malto-oligosaccharide mixture, the reduced mixture will have a superior color-fastness and thermal stability as compared to a similar unreduced mixture of malto-oligosaccharides, and also low reactivity towards nitrogen-containing species.

  • Publication number: 20030134394
    Abstract: Dextrins are prepared by hydrolyzing starch with an enzyme that consists essentially of a beta-amylase enzyme. The product prepared thereby will include a dextrin, such as beta-limit dextrin. Upon ultrafiltration of this product, a dextrin-rich fraction may be recovered. If desired, the dextrin-rich fraction may be further purified via diafiltration. Retrograded amylose may be separated from the product of enzymatic hydrolysis.

  • Publication number: 20030073798
    Abstract: Disclosed is a method for preparing a hydroxyalkyl starch. In accordance with the disclosed invention, the method comprises reacting the starch with a starch hydroxylating agent in the presence of an alcohol and an alcohol-soluble alkali metal, at a temperature effective to provide a cold water soluble starch, preferably at a temperature of between about 90° and about 110° C. The starch thus produced will be granular and cold water soluble.

  • Publication number: 20030060369
    Abstract: The present invention provides a method of retarding rootlet formation from one or more plants in a medium that can support the growth thereof, which method includes introducing into the medium a growth inhibiting effective amount of a growth inhibitor which comprises corn steep liquor. In other embodiments, the growth inhibitor is a mixture of a growth medium and lactic acid. In preferred embodiments, the present invention further provides a malting composition that includes a fermentable grain and a growth inhibitor, wherein the growth inhibitor is present in an amount effective to retard rootlet formation.

  • Publication number: 20030017221
    Abstract: Disclosed is a method for treating a grain fiber, in particular corn fiber. In accordance with the disclosed subject matter, the fiber is subjected to alkaline hydrolysis in the presence of a hemicellulose ferulate esterase in an aqueous medium. The hemicellulose ferulate esterase is present in an amount effective to catalyze alkaline hydrolysis, and the alkaline hydrolysis is performed under conditions suitable to permit the hemicellulose ferulate esterase to catalyze alkaline hydrolysis. The initial pH of the aqueous medium is alkaline but is sufficiently low to permit the enzyme to have catalytic activity. Preferably, the pH is in the range from 8.0 to 9.5. From the product mixture thus formed, fiber oil, cellulose, hemicellulose, and other materials may be obtained.

  • Publication number: 20030005922
    Abstract: The present invention provides a starch that includes at least one glucose polymer having greater than 4% alpha 1-6 glycosidic linkages. The present invention further provides a starch hydrolyzate that includes at least one glucose oligomer having greater than 4% alpha 1-6 glycosidic linkages. The starch and starch hydrolyzate present invention have improved aqueous solution stability and are less likely to retrograde than are solutions of unbranched linear starches or starch hydrolyzates.

  • Publication number: 20020132310
    Abstract: Disclosed are derivatized malto-oligosaccharides and methods for the preparation thereof. In accordance with the disclosed invention, a malto-oligosaccharide is hydrogenated to thereby obtain a hydrogenated malto-oligosaccharide, and the resulting hydrogenated malto-oligosaccharide is derivatized, such as via oxidation, esterification, etherification, or enzymatic modification. The derivatization of such hydrogenated malto-oligosaccharides results in a surprisingly low level of a formation of by-products and products of degradation. In a particularly preferred embodiment of the invention, a mixture of malto-oligosaccharides is catalytically hydrogenated under reaction conditions suitable to substantially preserve the degree of polymerization (DP) profile of the mixture. The resulting malto-oligosaccharide mixture then is derivatized to form a derivatized malto-oligosaccharide mixture.
