🧪🍞 Sourdough fermentation is driven by a symbiotic culture of wild yeast and lactic acid bacteria. (Weird, but true) As the dough ferments, these microorganisms consume carbohydrates and produce carbon dioxide, organic acids, and flavor compounds that give sourdough its distinctive texture and taste.
🔬 The acidic environment created during fermentation helps extend shelf life naturally. Lactic acid bacteria can break down some gluten proteins and fermentable carbohydrates, which may improve digestibility for some individuals.
🔬 A sourdough starter is a living microbial ecosystem, with its microbial composition influenced by flour type, feeding schedule, and local environment.
A simple combination of flour and water becomes a complex biochemical system! 🥖✨
