Sourdough is one of the oldest forms of grain fermentation. Experts believe it originated in ancient Egypt around 1500 B.C. and remained the main method of leavening bread menu. Until baker’s yeast replaced it a few hundred years ago.
Breads can be categorized as either leavened or unleavened สมัคร ufabet
Leavened breads have a dough that rises during the bread-making process. This is caused by the gas that’s released as the grain in the dough begins to ferment.
Most leavened breads use commercial baker’s yeast to help the dough rise.
On the other hand, unleavened breads, such as flatbreads like tortillas and roti, do not rise.
Sourdough bread is a leavened bread. However, rather than using baker’s yeast to rise. It’s leavened by “wild yeast” and lactic acid bacteria that are naturally present in flour.
Wild yeast is more resistant to acidic conditions than baker’s yeast. Which allows it to work together with lactic acid bacteria to help the dough rise.
Lactic acid bacteria are also naturally found in several other fermented foots, including yogurt, kefir, pickles, sauerkraut, and kimchi .
The mix of wild yeast, lactic acid bacteria, flour, and water used to make bread is called a starter. During the bread-making process, the starter ferments the sugars in the dough, helping the bread rise and acquire its characteristic flavor .
Sourdough bread also naturally contains varying levels of acetic acid bacteria. A group of bacteria that give sourdough bread its particular vinegar-like aroma.
Starters with high levels of acetic acid bacteria also take longer to ferment and rise, giving sourdough bread its characteristic texture.
The yeast naturally found in sourdough bread is also thought to increase the bread’s nutrient content. And make it easier for your body to digest than bread that’s made using baker’s yeast.
Despite its ancient roots.
sourdough bread making remains popular to this day. Maybe even more so as a result of the surge in interest in home baking. That has occurred during COVID-19 pandemic lockdowns throughout the world.
Keep in mind that not all store-bought sourdough breads are made using the traditional sourdough method. And this may reduce their health benefits.
Buying sourdough bread from an artisan baker or a farmers market increases the likelihood of it being “true” sourdough bread.
