Enzymes Replace Chemical Reducing Agents in Biscuit and Pizza Doughs
Bakers have used sodium metabisulfite to relax dough for decades, but sulfite labeling, allergen concerns, and clean-label programs push them toward protease enzymes that relax dough at 5 to 50 parts per million and are declared as processing aids. Enzyme relaxers cost 20% to 60% more per tonne of flour than sulfites, but they cut mixing time by 20% to 30% and lift line speed. Biscuit groups such as Mondelez and Kellanova run trials, and pizza chains use enzymes for stretch. Suppliers offer dosing guides for different flours, and blends of endo- and exopeptidases improve results.
