Abstract

See full text

An industrial process using kestose hydrolases to enable the use of sugar mixtures containing 1-kestose in the industrial production of sucrose (as crystallized sugar) by providing a method for the conversion of 1-kestose into sucrose and fructose in a sugar solution, containing kestose and more than 10 mM sucrose (3 g/L), and comprising the enzymatic hydrolysis (preferably using 1-FEH enzymes—EC 3.2.1.153) of 1-kestose. The process further provides a method of producing a polypeptide having 1-kestose hydrolase activity and a composition comprising the polypeptide.
