Patent ID: 8092609

Claim:
A method of inverting sucrose, comprising: (i) determining an initial solids concentration of an aqueous sucrose solution (solids i ), an initial bed volume (BV i ) 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 (HMF max ), a minimum target pH (pH min ), or a maximum target pH (pH max ); (ii) contacting the sucrose inversion resin system with a first portion of the aqueous sucrose solution under conditions of aqueous solution flow rate in BV i /hr (rate p ) and aqueous solution temperature in ° C. (temperature p ) to produce a first portion of an inverted sucrose solution having an inversion percentage (invert % product ), an HMF concentration (HMF product ), and a pH (pH product ); (iii) determining an instantaneous inversion percentage (invert % inst ), an instantaneous HMF concentration (HMF inst ), and an instantaneous pH (pH inst ) of the first portion of the inverted sucrose solution; (iv) leading the first portion of the inverted sucrose solution to downstream storage, and, if invert % inst <invert % min , invert % inst >invert % max , HMF inst >HMF max , pH inst <PH min , or pH inst >pH max (v) changing the aqueous solution flow rate, the aqueous solution temperature, or both of a second portion of the aqueous sucrose solution such that invert % min ≦invert % product ≦invert % max , HMF product ≦HMF max , or pH min ≦pH product≦pH max .
