These methods can comprise: (a) providing a food product/precursor that comprises at least water and fructose, and (b) contacting the food product/precursor with an epimerase that converts fructose to a fructose epimer, wherein at least one fructose epimer is produced in the food product/precursor. A glucosyltransferase enzyme (GTF) can be further included with the epimerase for contacting the food product/precursor, for example. Food products and food precursors produced by this methodology are also disclosed.
