Flour maturation is the controlled resting period following milling during which natural oxidation of pigments and gluten-forming proteins improves dough rheology and baking performance without the use of chemical improvers.
In trade practice
Mills typically rest flour in bulk bins or bags for several days to several weeks, depending on flour type and ambient conditions; temperature and humidity in the maturation store are monitored to prevent moisture uptake or pest ingress. Buyers may request rheological test results, such as farinograph or extensograph data, taken after a defined maturation period to confirm that the flour has reached its target handling properties. A frequent issue is flour being dispatched before adequate maturation, resulting in sticky or slack dough at the bakery. Where accelerated maturation agents are used instead, their permitted status under Regulation (EC) No 1333/2008 on food additives must be confirmed.
In a specification
A specification may state a minimum maturation period in days from milling date before dispatch, or alternatively require rheological parameters measured after maturation to fall within defined ranges, with the test method and maturation conditions stated.
