Abstract:
1. A process for producing a liquid low-calorie sweetener composition, comprising the steps of: a) drying b) treating the dried c) filtering the leaves-water mixture to obtain an aqueous filtrate; d) directly treating the aqueous filtrate with calcium hydroxide or calcium oxide to raise the pH of the aqueous filtrate to about 10; e) directly neutralizing the treated aqueous filtrate with trivalent iron chloride; and f) filtrating the neutralized aqueous filtrate to obtain a filtrated aqueous filtrate, and evaporating the filtrated aqueous filtrate to dryness to obtain purified sweet glycosides to provide a high intensity sweetener; g) providing sugar granules as a low intensity sweetener; h) dissolving the high intensity sweetener and low intensity sweetener in water to obtain a solution with 45-55% total solids; and i) evaporating the solution of high intensity sweetener and low intensity sweetener under vacuum to obtain the liquid low-calorie sweetener composition with a total solids content of about 60% to about 90%.
