Amorphous sucrose, containing citric acid as catalyst, undergoes thermolysis at 100 degrees to yield fructofuranosyl cation and D-glucose. The cation reacts with unchanged sucrose to form all three of the known kestoses, and also their alpha-fructofuranosyl anomers. Two of the latter are resistant to invertase hydrolysis. A new fructosylglucose disaccharide is also formed.
含有柠檬酸作为催化剂的无定形蔗糖在100摄氏度下进行热解,生成呋喃果糖基阳离子和D-葡萄糖。该阳离子与未反应的蔗糖反应,形成所有三种已知的蔗果三糖,以及它们的α-呋喃果糖基端基异构体。后两者中的两种对转化酶水解具有抗性。还形成了一种新的果糖基葡萄糖二糖。
