摘要： A process for preparing crystalline 1-kestose which enables crystalline 1-kestose in large fine granulated sugar form to be prepared with high recovery. The process comprises concentrating a high-purity 1-kestose solution to a Brix of not less than 75, depositing crystallites serving as a mother nucleus by adding seed crystals or by concentration under reduced pressure, and repeating at least twice the step of growing crystals by concentration under reduced pressure and the step of redissolving crystallites produced in the concentrate. Alternatively, the process comprises concentrating a high-purity 1-kestose solution to a Brix of not less than 80, growing crystals after addition of seed crystals or induction of crystallization, and repeating at least twice the step of lowering the temperature by 5 to 20 DEG C below the temperature in the previous step and the step of growing crystals growth by allowing the concentrate to stand at the above temperature. An enzyme capable of efficiently converting sucrose to 1-kestose is also disclosed.
