CO₂ Bubbles /ˌsiː.oʊ tuː ˈbʌbəlz/

CO₂ bubbles are small gas pockets that form in dough during the fermentation process.
They are created when yeast consumes sugar and produces carbon dioxide gas.
These bubbles help make bread soft and airy by expanding as the dough rises.
In addition to bread, CO₂ bubbles can also be found in other baked goods like cakes and pastries.
The presence of these bubbles is important for achieving the desired texture in baked products.
Bakers carefully control the fermentation process to ensure the right amount of CO₂ bubbles in their dough.

二氧化碳气泡是在发酵过程中面团中形成的小气体囊泡。
它们是在酵母消耗糖分并产生二氧化碳气体时产生的。
这些气泡有助于使面包变得柔软和蓬松，因为它们会在面团发酵时膨胀。
除了面包，二氧化碳气泡也可以在其他烘焙食品中找到，如蛋糕和点心。
这些气泡的存在对于达到烘焙产品所需的质地至关重要。
面包师仔细控制发酵过程，以确保面团中有适量的二氧化碳气泡。
