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 othr 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.
Abstract:
Disclosed is a composition that includes a material that is susceptible to degradation and a preserving agent in an amount effective to preserve the material comprising one or more reduced malto-oligosaccharide species. The preserving agent can include a single reduced malto-oligosaccharide species or a plurality of such species. Further disclosed is a method of preserving a material. The method generally includes contacting the material with a preserving agent containing a preserving effective amount of one or more reduced malto-oligosaccharide species. Solutions, powders, glasses, gels, and the like containing the chemically reactive material(s) and a preserving effective amount of one or more reduced malto-oligosaccharide species may be prepared.
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.
Abstract:
Disclosed are saccharide-derivatized oligosaccharides. The derivatized oligosaccharides preferably are prepared by extruding a malto-oligosaccharide mixture with a saccharide or mixture of saccharides having a DP ranging from 1 to 4. The products are low in digestibility, and thus in various embodiments are suitable for use as bulking agents, for controlled energy release products, and for other purposes.
Abstract:
Maltose products are prepared by hydrolyzing starch with an enzyme that consists essentially of a beta-amylase enzyme. The product thus prepared may be spray dried, or a high purity maltose product may be obtained therefrom via ultrafiltration. The high purity maltose product has a low content of glucose and saccharides in the DP 3-10 range.
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.
