Is the temperature of 40 ℃ fermented dough high

The temperature of the fermented dough at 40 ℃ is relatively high, and it is usually recommended to control it between 28-32 ℃. The fermentation temperature of dough is mainly affected by factors such as yeast activity, environmental humidity, dough composition, fermentation container material, and operation mode. Yeast activity is significantly enhanced at 40 ℃, but excessively high temperatures may cause yeast to prematurely deplete sugar, produce excessive acidic substances, and affect dough extensibility and final taste. High temperature can also accelerate the denaturation of gluten protein, making the dough structure loose, resulting in a small volume and rough texture of the baked product. Although some high-temperature tolerant yeasts can adapt to an environment of 40 ℃, the survival time of ordinary yeasts will be shortened at this temperature.

professional baking occasionally uses 38-40 ℃ for rapid fermentation, but it is necessary to strictly control the time within 20 minutes and use high sugar formulas or add amendments. When home production lacks precise temperature control equipment, problems such as excessive fermentation and excessive acidity are prone to occur when the temperature exceeds 35 ℃. Using refrigerated ingredients or ice water to regulate temperature is safer and more reliable.

For daily production, it is recommended to dissolve the yeast in warm water and let it stand to activate. When the dough is fermented, cover it with a damp cloth and place it in a warm place. In winter, the fermentation function of the oven can be utilized, but a thermometer needs to be placed inside the chamber for real-time monitoring. The standard for fermentation completion is to increase the volume by 2 times and slowly rebound when pressed with fingers. If there is excessive expansion or collapse, the temperature needs to be adjusted and the operation needs to be restarted. Reasonably controlling the fermentation temperature can ensure that the bread tissue is delicate and the flavor is balanced.
