As consumers rediscover the nutritional benefits of bread, there’s increasing demand for transparency, simplicity and authenticity. Consequently, bread labels are more and more often clean(er) label. Consumers are also looking for more grains and seeds to improve the nutritional value. But they want to go beyond that. ‘Bread with sourdough’ has become a favourite bread during the Covid crisis, as it has become part of a healthier diet – 3rd after ‘bread rich in fibre’ and ‘breads with more grains’ and preferred over ‘high in protein, low in salt’ and ‘gluten free’ bread. It is encouraging more and more bakers to re-think the very essence of their bread, namely, the way it’s fermented.
Typically, longer sourdough fermentation – of about 20 hours – results in more premium bread characteristics. A well-executed long fermentation ensures breads have a rustic look on the crust, a more open and ‘waxy’ crumb that has a cohesive, moist and elastic-like texture, and a rich flavour.
Such rustic-style breads draw inspiration from the past. For thousands of years, bakers relied on the natural fermentation of sourdough to slowly leaven their breads. The popularity of sourdough has been growing for many years now, but with many major bakeries launching their own long-fermented breads with sourdough, sourdough is here to stay and promises to play a major role in bread making of the future.
Adopting longer fermentation is an art to master, and a science to perfect. Remember, the reason sourdough nearly disappeared from the market was because of its complexity and how difficult it was to control compared to the convenience of baker’s yeast. During long fermentation, the dough is naturally filled with gas to create a consistent, open structure that’s full of flavour. Temperature and time control is vital and once the dough is fully fermented, it is important that it is handled very carefully. To deliver handmade style breads, bakers must therefore adapt their baking technologies when handling this stickier, more gaseous, long-fermented dough.
While you are masters in the making of your bread, you can rely on us to master the fermentation of your sourdoughs. By understanding every facet of natural fermentation, we guarantee you the consistency you need, and the diversity in flavours consumers expect. It’s an expertise we even apply to wholegrains as well, creating exclusive fermented Sprouted Grains.
New research done by Professor Marco Gobbetti has shown that the choice between commercial baker’s yeast and sourdough not only impacts breads’ volume, taste and texture, but can also have a significant impact on its digestibility. As a consequence, Puratos is working on short- and long-term projects that will bring to market high quality gut-friendly ingredients to meet consumers’ demand for even healthier breads. The benefits of long fermentation and sourdough on health will therefore be better understood, and will gain still more traction.
In conclusion, it is possible to control every facet of the process when preparing long-fermented sourdough breads.
