How long does it take for two pounds of flour to ferment

fermentation of two pounds of flour generally takes 1-2 hours, and the actual time is affected by factors such as yeast activity, ambient temperature, sugar addition, dough moisture content, and kneading degree. Yeast activity is a key factor determining fermentation rate. Fresh yeast or active dry yeast can rapidly reproduce and produce gas under suitable conditions. If yeast is stored for too long or improperly, it may lead to a decrease in activity. Before use, warm water can be added with a small amount of sugar to test whether yeast produces foam. If there is no foam, yeast needs to be replaced. In winter, it is advisable to increase the amount of yeast or extend the fermentation time appropriately. The environmental temperature has a significant impact on fermentation efficiency. 25-30 degrees Celsius is the optimal fermentation temperature range, and the fermentation time may be shortened to 40 minutes when the room temperature is high in summer, and extended to more than 3 hours in low temperature environments in winter. You can place the dough in a sealed container and place a bowl of hot water next to it to increase the local temperature. Avoid temperatures exceeding 35 degrees Celsius, as high temperatures can kill yeast or cause fermentation to occur too quickly, resulting in a sour taste. After fermentation is complete, the dough volume should expand to about twice its original volume, and the slow rebound after poking the hole with the finger indicates that fermentation is complete. If making Mantou, steamed stuffed buns and other wheaten foods that need secondary fermentation, they can be divided and shaped after the first fermentation, and stand for 15-20 minutes for secondary rejuvenation. Pay attention to the differences in water absorption of different types of flour. The fermentation time of whole wheat flour and other coarse grain flour is usually 10-15 minutes longer than that of refined white flour. insufficient fermentation can lead to a tight texture in the finished product, while excessive fermentation can produce a sour taste and a decrease in fluffiness.
