- Formation of trisaccharides (kestoses) by pyrolysis of sucrose
-
Amorphous sucrose, containing citric acid as catalyst, undergoes thermolysis at 100° to yield fructofuranosyl cation and D-glucose. The cation reacts with unchanged sucrose to form all three of the known kestoses, and also their α-fructofuranosyl anomers. Two of the latter are resistant to invertase hydrolysis. A new fructosylglucose disaccharide is also formed. Amorphous sucrose, containing citric acid as catalyst, undergoes thermolysis at 100° to yield fructofuranosyl cation and D-glucose.
