Hydrolysis

Concept

Hydrolysis is a break down of a chemical bond by addition of water. The reaction is catalyzed either by acids or, more common in the biobased industries for their beneficial process properties, by enzymes.

In bioprocess applications, hydrolyzation is used to break the molecular structure of polymers such as starch, cellulose, or inulin, into smaller fractions of polysaccharides (= polymers of sugar molecules) and ultimately to glucose or fructose.

Applications

Vogelbusch applies two-step enzymatic conversion processes (liquefaction and saccharification) that are adjusted to either

  • Gain a maximum of monosaccharides (glucose) that serve as a fermentation substrate or to
  • Provide a starch hydrolysate with a custom made sugar profile ranging from maltodextrin syrups to high DE glucose syrups.
