Study reveals how wheat fibers transform in Sourdough.Sourdough bread has been enjoyed for thousands of years. It is now making a comeback worldwide. Many people appreciate it for its natural fermentation, rich flavor, and possible health benefits. However, the biological processes in sourdough are still quite complex.
A new study from Vrije Universiteit Brussel sheds light on what happens during sourdough fermentation. The research reveals how wheat fibers known as Arabinoxylans change during fermentation and influence the final quality of bread.
The study was led by doctoral researcher Víctor González Alonso, who investigated how these fibers interact with the microorganisms that drive sourdough fermentation.
The team concentrated on arabinoxylans, an important type of dietary fiber in wheat. These fibers come in two main forms. Water-extractable arabinoxylans (WE-AX) usually support good dough structure. Water-unextractable arabinoxylans (WU-AX) can harm bread quality.
During sourdough fermentation, the researchers found that part of the WE-AX fibers are converted into WU-AX.
Despite this transformation, the fermentation process remained stable even when extra fiber was added to the dough.
