HCID 5984D-(-)-Fructose

Procedure

Operating the system in accordance with the conditions set forth in Table 1 results in a 97% recovery of dextrose in the raffinate stream and 87% recovery of fructose in the extract stream. The higher sugars, which include maltose, triose and higher saccharides, are also concentrated in the raffinate stream as compared to the extract stream. The extract stream is readily concentrated in suitable evaporators to provide a high fructose syrup having a dry solids (ds) of 77 percent, and a fructose content of 90-94% by weight dry solids basis.

  1. concentrationare also concentrated in the raffinate stream
  2. concentrationThe extract stream is readily concentrated in suitable evaporators
