Abstract: A method of continuously producing hard-candy masses from an aqueous solution of starting ingredients by boiling and condensing the solution, subjecting it to a vacuum, condensing it further and cooling it, adding flavorings, dyes, etc., and finally cooling it again and shaping it into candy. The starting ingredients are sugar substitutes and the solution is subjected to a vacuum as early as while it is being boiled and while it is being condensed and will accordingly have a temperature that is low enough for conventional flavorings, a viscosity that is high enough for conventional cooling and tempering, and a low enough residual-water content.
