What You Need to Know
Freshly milled flour contains active lipoxygenase (LOX) and glutathione reductase, which degrade carotenoids and weaken gluten. Aged flour undergoes oxidative maturation, improving dough elasticity via disulfide bond formation.
Critical for artisan bread texture; fresh-milled flour produces denser crumb while aged flour yields better oven spring.
