Post-harvest drying method for American ginseng

Abstract

The invention discloses a post-harvest drying method for American ginseng. The post-harvest drying method comprises the following steps: pre-treating, grading, performing ultraviolet radiation, performing air-drying, performing NO fumigation and drying. The product quality of the American ginseng processed by the method is improved while the American ginseng is dried, content of active ingredients in the American ginseng can be greatly increased, color and luster, taste and nutrient ingredients of fresh American ginseng are completely kept, uniform water separation speed and a sufficient drying effect are achieved, and loss, caused by high-temperature heating, of various active ingredients is prevented; the content of the active ingredients of the dried American ginseng is obviously increased, and the content of main components such as ginsenoside is far higher than that by an existing drying method; and moreover, the dried product is uniform in color and luster, is stable in quality, is high in bioavailability, is strong in activity, is high in quality, is low in water content, is good in stability and is long in guarantee period.

Description

technical field [0001] The invention belongs to the technical field of medicinal material processing, and relates to a post-harvest drying method of American ginseng.

AI Technical Summary

Problems solved by technology

However, after slicing, the epidermis is destroyed, and the contact surface area between the internal tissue and the external space increases, which instead increases the loss, destruction and deterioration of the active ingredients in American ginseng during processing.

[0005] In addition, vacuum drying, infrared drying, microwave drying and other methods are also used in the prior art. When the whole ginseng is dried, the disadvantages of uneven water content inside and outside the dry product and loss of active ingredients still exist, and the drying effect is still not ideal. poor overall effect

Moreover, the processing process is complicated, the equipment configuration requirements and cost are high, and it is not suitable for popularization and application.
