Patent number: 4132595Abstract: A process for production of dextrose from starch wherein a starch hydrolysate having a high dextrose equivalent produced using soluble glucoamylase is treated solely with an immobilized glucoamylase enzyme to produce a dextrose product.Type: GrantFiled: December 13, 1976Date of Patent: January 2, 1979Assignee: CPC International Inc.Inventors: Ronald E. Hebeda, Dennis J. Holik, Harry W. Leach
-
Patent number: 4104212Abstract: Covers a process for producing an improved substantially non-birefringent granular starch product comprising: heating an aqueous slurry of a granular birefringent starch to substantially eliminate the birefringence of the starch and to slightly swell the starch while retaining the granule structure; separating and dehydrating the partially swollen non-birefringent starch granules; and recovering the substantially non-birefringent granular starch product. Also covers the use of this product as a thickener to increase the viscosity and to improve the coating characteristics of latex compositions and said latex compositions.Type: GrantFiled: November 26, 1976Date of Patent: August 1, 1978Assignee: CPC International Inc.Inventor: Robert L. Bruner
-
Patent number: 4104213Abstract: This invention discloses latex compositions wherein a specially treated, substantially non-birefringent, cold water swelling, granular starch product is used as a thickener and for partial replacement for the polymer in the latex.Type: GrantFiled: November 26, 1976Date of Patent: August 1, 1978Assignee: CPC International Inc.Inventors: Mutong T. Chiang, John P. Gibbons
-
Patent number: 4086135Abstract: A process for steeping grain wherein the steepwater is inoculated with an inoculum containing a microorganism of the genus Lactobacillus at or near the beginning of the steeping process. The process reduces the steeping time and increases the content of lactic acid in the steepwater. The process also reduces the amount of sulfur dioxide needed in the steeping process.Type: GrantFiled: December 16, 1974Date of Patent: April 25, 1978Assignee: CPC International Inc.Inventors: Ramon Cairo Balana, Antonio Montserrat Caixes
-
Patent number: 4085075Abstract: A resin blend useful in molding compounds wherein a novolak resin, a carbohydrate and an aminoplast are blended with fillers and the like to form a molding composition curable with cross linking agents. Articles molded in the molding composition of the invention have good flow characteristics, physical and mechanical properties, and provide molded articles with uniform, smooth surfaces which can be pigmented with bright colors.Type: GrantFiled: June 29, 1977Date of Patent: April 18, 1978Assignee: CPC International Inc.Inventors: John P. Gibbons, Mutong T. Chiang
-
Patent number: 4085076Abstract: A carbohydrate-phenolic resol resin and a process for production of same wherein an aldose saccharide, preferably a hexose, is reacted with a phenolic compound and urea in the presence of an acid catalyst to form a liquid fusible resin which is reacted with a lower aliphatic aldehyde in the presence of a basic catalyst to form said resol resin.Type: GrantFiled: June 21, 1977Date of Patent: April 18, 1978Assignee: CPC International Inc.Inventors: John P. Gibbons, Lawrence Wondolowski
-
Patent number: 4073963Abstract: Stable, homogeneous buttered table syrups are obtained by incorporating in the table syrup formulations an emulsion system consisting of at least 0.1% by weight sodium stearoyl-2-lactylate, at least 0.2% by weight sorbitan monostearate, and at least 2.0% by weight butter. The sugar solids content of the table syrup is adjusted to be no less than 65% Brix, its viscosity is no less than about 300 cps and its pH is about 4.0-5.5. Table syrups containing the emulsion system exhibit good clarity and prolonged shelf life stability.Type: GrantFiled: December 27, 1976Date of Patent: February 14, 1978Assignee: CPC International Inc.Inventor: Elmer E. Daggy
-
Patent number: 4059458Abstract: Oil-in-water emulsions containing starch carboxylates as the emulsifying agent.
