Abstract

We disclose a method of inverting sucrose, including (i) determining an initial solids concentration of an aqueous sucrose solution (solidsi), an initial bed volume (BVi) of a sucrose inversion resin system, a minimum target inversion percentage (invert %min), a maximum target inversion percentage (invert %max), a target maximum hydroxymethylfuran (HMF) concentration (HMFmax), a minimum target pH (pHmin), or a maximum target pH (pHmax); (ii) contacting the sucrose inversion resin system with the aqueous sucrose solution under conditions of aqueous solution flow rate in BVi/hr (ratep) and aqueous solution temperature in ° C. (temperaturep) to produce an inverted sucrose solution having an inversion percentage (invert %product), an HMF concentration (HMFproduct), and a pH (pHproduct); (iii) observing an instantaneous inversion percentage (invert %inst), an instantaneous HMF concentration (HMFinst), or an instantaneous pH (pHinst) of the inverted sucrose solution; and, if invert %inst<invert %min, invert %inst>invert %max, HMFinst>HMFmax, pHinst<pHmin, or pHinst>pHmax; (iv) changing at least one of the aqueous solution flow rate or the aqueous solution temperature such that invert %mi…
