Manufacturing method of automatically fermenting sweet potato flour coarse food grain products

Abstract

The invention discloses a manufacturing method of automatically fermenting sweet potato flour coarse food grain products. The process of the manufacturing method comprises: slicing sweet potatoes; coating flour on the sliced sweet potatoes, drying the flour-coated sweet potato slices, grinding the dried sweet potato slices into fine powder, and obtaining the sweet potato flour; mixing the sweet potato flour with coarse food grain powder, adding yeast or baking power, uniformly mixing for later use; kneading dough by mixing the powder with warm water and placing at room temperature for 30 to 40 minutes for automatic fermentation; and after fermentation, making cooked wheaten food such as steamed breads, cakes, steamed bread rolls, etc. In the invention, nutritive grains are combined with the sweet potatoes which are the favorite of people, and fragrant and sweet wheaten food can be made by using the natural sweet mouthfeel offered by the sweet potatoes without any sugar nor sweetener. Thus, the problem that the coarse food grain powder offers a poor mouthfeel and is too coarse to eat and the problem that the sweet potato products product lots of gastric acid and cause heartburn and other discomforts are solved. The automatically fermenting sweet potato flour coarse food grain products offer good mouthfeel, unique flavor, sweetness and fragrance, and can ferment automatically; the manufacturing process is simple, the food culture of people is enriched, and a food with rich nutrients is provided for people.
