Patent GB-1116888-A (GB)
Title: Process for the production of invert sugar solutions from molasses
IPC: C13B35/06
Filed: 1967-03-14
Abstract: Pure invert sugar solutions are produced from molasses by first subjecting the molasses to an acidic hydrolysis and then, after optional neutralization, separating chromatographically with a cation exchange resin in the salt form. If desired the hydrolysis may be carried out for a period of time longer than that necessary for the complete hydrolysis of the sucrose present into glucose and fructose. The chromatographic separation by an ion exclusion process is preferably carried out, e.g. using a nuclear sulphonated polystyrene cationic resin charged with alkali metal ions, at a temperature between 50 DEG  and 100 DEG  C. although a temperature above 100 DEG C. may be used under superatmospheric pressure.  The molasses may be hydrolysed either by adding hydrochloric acid to the molasses to give a pH of 1 to 4, heating the mixture for 20 to 120 minutes at 60 to 105 DEG  C. and, if desired, passing sulphur dioxide into the molasses before, during or after the hydrolysis; or by using sulphur dioxide alone.  The hydrolysate is then neutralized, e.g. with a solution of sodium or potassium hydroxide or with a weakly basic anion exchanger, prior to the chromatographic separation.  In an alternative embodiment of the invention wherein the hydrolysate is separated without prior neutralization the hydrolysis is preferably carried out using sulphuric acid.  The resulting acidic solution is applied to the salt charged cation exchange resin and salts are washed out until an equilibrium amount of metal ions have been replaced by hydrogen ions whereafter the invert sugar is eluted.  In this case the ion exchange resin preferably contains not only cations but also hydrogen ions in an amount corresponding substantially to the equilibrium concentration in the hydrolysis solution.  The examples describe the hydrolysis of molasses containing specified amounts of sucrose, fructose and glucose under various conditions and the separation of invert sugar from the hydrolysate. Aconitic acid may be isolated from cane sugar molasses by chromatographic separation of acidic hydrolysates without neutralisation.
