Abstract

The present invention relates to a process of preparing commercial quantities of glucose and/or fructose from sucrose, a process of preparing commercial quantities of glucose and a polyfructan from sucrose, a reactor for practicing same, a process of preparing commercial quantities of fructose and a polyglucan from sucrose and a reactor for practicing same.

Claims

1. A reactor for preparing commercial quantities of glucose comprising:

(a) a reactor vessel,

(b) an inlet for sucrose;

(c) an outlet for glucose; and

(d) a fructosyltransferase.

2. The reactor of claim 1, further comprising an outlet for a polyfructan.

3. The reactor of claim 1, wherein said inlet for sucrose is a continuous inlet.

4. The reactor of claim 1, wherein said outlet for said polyfructan is a continuous outlet.

5. The reactor of claim 1, wherein said outlet for glucose is a continuous outlet.

8. The reactor of claim 1, further comprising a separator located between said reactor vessel and said outlet for glucose.

9. The reactor of claim 2, further comprising a separator located between said reactor vessel and said outlet for polyfructan.

6. A reactor for preparing commercial quantities of fructose comprising:

(a) a reactor vessel;

(b) an inlet for sucrose;

(c) an outlet for fructose; and

(d) a glucosyltransferase.

7. A reactor for preparing glucose and fructose from sucrose comprising:
