Abstract
Sucrose is treated with an acid catalyst to form an amorphous sucrose anhydrous melt. Heating of the anhydrous melt at 80.degree.-100.degree. C. forms three known kestoses and the novel products, viz. .alpha.-fructosylsucrose anomers of 6-kestose, neokestose, and 1-kestose. Heating of the anhydrous melt at 125.degree.-175.degree. C. produces a fructoglucan sucrose polymer having a molecular weight of about 2,000 to 10,000 Daltons. All of these products are useful as sweeteners, food additives, additives for animal food, and bulking agents.
