Preparation method of dendrobium officinale

Abstract

The invention discloses a preparation method of dendrobium officinale. The method comprises the following steps: 1) flatly paving the selected dendrobium officinale on a first bracket and baking for 30 to 60 minutes at a temperature of 50 DEG C to 80 DEG C; 2) putting the baked dendrobium officinale on a second bracket and drying. According to the technical scheme, the temperatures during the baking twice are both low, so that nutritional ingredients in the dendrobium officinale are ensured on the basis that water in the dendrobium officinale is effectively removed. Based on the technical scheme, according to the preparation method, firstly, the majority of water in the dendrobium officinale is removed by baking the dendrobium officinale at a fire of 50 DEG C to 80 DEG C, and then the dendrobium officinale is dried. Thus, compared with the treatment mode of direct high-temperature baking in the prior art, according to the method disclosed by the invention, the temperatures during the baking twice are both low, so that the nutritional ingredients in the dendrobium officinale are not damaged. As a result, the nutritional ingredients in the dendrobium officinale are ensured on the basis that the water in the dendrobium officinale is effectively removed.
