Abstract:
1. A process for producing sucralose from a feed mixture comprising an acyl-sucralose compound in an aqueous solution, wherein said process comprises: (a) adjusting the pH of said feed mixture to a range of about 8.0 to about 12.0; (b) maintaining said feed mixture at an appropriate temperature for sufficient time to effect conversion of said acyl-sucralose compound into free sucralose; (c) adding a buffer to said feed mixture in an amount sufficient to stabilize said pH within said range for the duration of said maintaining step; (d) decreasing said pH of said feed mixture to about 4 to about 8; and (e) recovering sucralose from the product of step (d), thereby obtaining a recovered sucralose.
