The disclosed method for preparing a fluid absorber generally comprises the steps of selecting a starch and an enzyme for hydrolysis of the starch, determining a fluid absorption optimum hydrolysis level for the starch, and ezymatically hydrolyzing the starch to approximately the optimum level thus determined. The starch alternatively may be hydrolyzed with acid hydrolysis without the use of an enzyme catalyst. The disclosed method for absorbing fluid from the skin includes the step of applying a fluid absorbing effective amount of a fluid absorber thus prepared. Absorption properties of the fluid absorber of the invention are comparable to or exceed those of commercially available skin fluid absorbers, such as talc and unmodified corn starch.Type: ApplicationFiled: June 11, 2003Publication date: October 30, 2003Applicant: Grain Processing CorporationInventors: Helene G.

Publication number: 20030134394Abstract: 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.Type: ApplicationFiled: January 24, 2003Publication date: July 17, 2003Applicant: Grain Processing CorporationInventors: Richard L. Antrim, Clark P. Lee

Patent number: 6444448Abstract: There is provided a method of production of an immunostimulatory &bgr;-glucan-mannan preparation, comprising the step of autolysis of cells of a microorganism at a pH of 5 to 6 and a temperature of 35 to 60° C. for 6 to 48 hours, and separating solid material roam the autolysed product. The &bgr;-glucan-mannan preparation may be incorporated as a food component or be used as a pharmaceutical for treatment of conditions such as immuno-suppression, hypercholesterolaemia, hypoglycaemia and heavy metal excretion.Type: GrantFiled: June 24, 1998Date of Patent: September 3, 2002Assignee: Carlton and United Breweries, LimitedInventors: Ragini Wheatcroft, Joseph Kulandai, Robert White Gilbert, Keith James Sime, Craig Gordon Smith, Willem Hendrik Langeris

Patent number: 6436678Abstract: 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.Type: GrantFiled: February 28, 2001Date of Patent: August 20, 2002Assignee: Grain Processing CorporationInventors: Richard L. Antrim, Clark P. Lee
