Abstract
The invention discloses a method for preparing tea by using pungent abelmoschus leaf and application, belonging to the technical field of food processing. The method comprises the following steps of: picking, cleaning, drying, removing moisture, and drying to obtain the pungent abelmoschus leaf tea finished product. The pungent abelmoschus leaf is rich in active components such as flavone and polysaccharide, and nutritional ingredients such as protein, fat and micro elements, has a low utilization rate at present, and causes huge waste of the resources when being discarded to the field as waste. The method has the characteristics that (1) the pungent abelmoschus leaf which is originally regarded as waste is sufficiently utilized, efficient comprehensive utilization of the pungent abelmoschus resource is realized, and the economic benefits for planting the pungent abelmoschus are improved; (2), the pungent abelmoschus leaf tea is simple in preparation method, has aromatic odor, refreshing taste, yellow-green color and unique mouthfeel after being brewed by boiling water, a high nutritive value and an antioxidant health-care effect, and provides a novel green healthy drink for the consumers; and (3), the pungent abelmoschus tea solution can be used for preparing antioxidant functional food.
