Abstract
The invention provides a drying method for fig leaves. The drying method comprises the following steps: pre-treating, cooling with air and drying, drying, crushing and packaging. In a drying process, a gradient temperature varying and humidity varying manner is adopted; and the content of total flavonoids in a product, namely fig leaf powder, is detected through a UV (Ultraviolet) method, so that quality evaluation is carried out. By utilizing air-cooling and drying, and ''closed-ring dehumidifying-heat pump drying'' technologies, original tissue shapes, flavors and nutrient components of the fig leaves can be kept to the greatest extent; and the drying method is simple in process and simple and convenient to operate.
