Diacetone fructose hydrolysis with water-insoluble catalysts

摘要

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.
