Abstract:
A process for obtaining sucrose from a sucrose-containing syrup, comprising the steps of:(a) nanofiltration of a feed syrup that comprises sucrose and no less than about 3% by weight invert sugars (on a dry solids basis) using a nanofiltration membrane, whereby a nanofiltration permeate and a nanofiltration retentate are produced, wherein the nanofiltration permeate comprises invert sugars, and wherein the nanofiltration retentate has: (i) a concentration of sucrose that on a dry solids basis is higher than the concentration of sucrose in the feed syrup, and (ii) a concentration of invert sugars that on a dry solids basis is lower than the concentration of invert sugars in the feed syrup; and (b) recovery of the nanofiltration retentate.
