Natural dried-fruit yeast and natural dried-fruit bread preparation method

The invention discloses a natural dried-fruit yeast and natural dried-fruit bread preparation method. The method includes: well mixing fermentation raw materials, adding into a sterile container, sealing, fermenting in an environment at a constant temperature of 22 DEG C and a humidity of 50%, and uncovering once a day to keep air circulation to finally obtain yeast liquid after all dried fruits float on the surface and the upper liquid layer is full of rich foams, wherein the fermentation raw materials include dried fruits, auxiliary nutrients and sterile water; subjecting the yeast liquid and flour to activation for 3-5 times to obtain natural dried-fruit yeast. Bread flour, sugar, milk, eggs, water, the natural dried-fruit yeast, salt and butter are mixed to form bread dough, and the bread dough is subjected to dividing, shaping, fermenting and baking to obtain natural dried-fruit bread. The natural dried-fruit bread prepared through the natural dried-fruit yeast is rich in taste and palate level due to co
