1, bread fermentation can be put in the refrigerator, but if it is fermented dough, it can't be put in the refrigerator, otherwise it will stop fermentation. The storage temperature in the refrigerator is mostly below 5 degrees Celsius, and the optimal fermentation temperature of dough is between 20 degrees Celsius and 30 degrees Celsius. If it is lower than this temperature, the fermentation will be very slow or even stop.

2, dough fermentation in the refrigerator is called refrigerated dough, also known as low-temperature dough, which is to put the dough with yeast powder into the freezer of the refrigerator and let the yeast grow and reproduce slowly in a low temperature environment.

Generally speaking, if you put the dough in the refrigerator, it is to control the fermentation time. By controlling the temperature and fermentation speed, different tastes and flavors can be obtained.
