Furthermore, the process condition for preparing the tea bread by the cold storage medium fermentation method is reliable, the dough is easy to control, the two sections of dough preparation and bread baking are effectively separated, a reference basis can be provided for the industrial production of the tea bread, and the industrial and large-scale production of the tea bread is promoted.
2. The honey added in the invention has the following functions: (1) increase the hygroscopicity and softness of the dough; (2) the sweetness of the bread is increased; (3) the nutritional ingredients of the bread are increased; (4) the adverse effect of dough fermentation effect caused by adding tea powder is reduced.
3. After the bread dough (the bread dough obtained by fermenting, dividing and molding the main dough is obtained) is obtained, the bread dough is proofed, and the proofed effect is as follows: (1) the dough is recovered with flexibility; (2) ensuring the gluten network to be fully expanded; (3) the product tissue is loosened.
4. According to the invention, honey is used for replacing the traditional cane sugar, and tea powder is added into flour to prepare the new-taste bread, so that the product is fine and smooth in taste, high in filling power and low in calorie, and the pursuit of modern young people on convenient, low-calorie and high-nutrition diet is met.
