Abstract: In one embodiment, fat and/or protein liberated during a starch hydrolysis operation is suitably removed from the resulting starch hydrolysate solution by contacting said solution with a non-hydrolyzed granular starch material in a fashion so as to adsorb and/or coat said fat and/or protein onto said granular starch material and thereafter separating the resulting fat and/or protein containing starch material from said starch hydrolysate solution. In another embodiment, granular starch remaining non-hydrolyzed following a direct, granular starch hydrolysis process and having liberated fat and/or protein residues coated, adsorbed or otherwise accumulated thereon is pasted, thinned, separated from said fat and/or protein residues and recycled to said granular starch hydrolysis process for further hydrolysis to glucose therein.

Abstract: DIACETONE FRUCTOSE HYDROLYSIS WITH WATER-INSOLUBLE CATALYSTS Diacetone fructose solutions may be effectively hydrolyzed to fructose by acid exchange resins. Hydrolysis of diacetone fructose with acid exchange resins substantially reduces the formation of objectionable flavoring, coloring and other hydrolyzate by-products. The immobilized acid catalysis provides a fructose product substantially free from ash residues and significantly reduces the carbon, cation and anion exchange requirements for the manufacture of enriched, food-grade fructose syrups. Perfluorinated acid exchange resins have been found to be particularly effective for hydrolyzing aqueous diacetone fructose solutions into fructose.

Abstract: ALKYLIDENATION OF FRUCTOSE WITH PERFLUORINATED ACID CATALYSTS Aqueous fructose and aldehydes, ketones and/or acetals may be effectively catalyzed into alkylidene fructose derivatives with immobilized acid catalysts. The reaction provides a means for enriching the fructose content of conventional high fructose co m syrups. Perfluorinated acid resins are especially effective catalysts for converting aqueous fructose and acetone solutions into diacetone fructose. Catalysis with the perfluorinated acid resins may be conducted at significantly lower conversion temperates with superior reactant and reaction product exchange rates. Enrichment of high fructose corn, syrups may be generally accomplished by catalyzing the fructose and acetone into a diacetone fructose solution with the perfluorinated acid resin, allowing the dextrose to precipitate from the diacetone solution, hydrolyzing the diacetone fructose to fructose and recovery of the enriched fructose product therefrom. The water-insoluble catalysts afford a reusable catalyst system which can be easily separated from the processed products. The perfluorinated acid resins produce a high quality, food-grade syrup products essentially free of ash, organoleptic bodies (e.g. flavoring, coloring, etc.) and other objectionable by-product contaminants.
