  • Patent number: 4605619
    Abstract: Process for preparing fructose by treating starch with alpha-amylase, contacting the resulting liquefied starch with glucoamylase to hydrolyzed said starch to glucose, and isomerizing at least part of the resulting glucose to fructose by contacting said glucose with glucose isomerase. The three enzymes are obtained from organisms of the Basidiomycetes class of fungi.

  • Patent number: 4431733
    Abstract: Process for preparing fructose from liquefied starch by contacting the liquefied starch with glucoamylase to hydrolyze said starch to glucose and contacting the glucose so produced with glucose isomerase to isomerize at least a part of the glucose to fructose. The glucoamylase and glucose isomerase are obtained from an organism of the Basidiomycetes class of fungi.
