Method for rapidly drying fresh whole angelica roots

Abstract

The invention discloses a method for rapidly drying fresh whole angelica roots. The method comprises the following steps: collecting fresh whole angelica roots; cleaning to remove silt; draining and airing; drying in a far infrared manner; measuring the water content; and vacuumizing and packaging. Compared with the traditional drying method, the method disclosed by the invention has the advantages that the drying time is greatly shortened; the drying efficiency is increased; simultaneously, effective components in angelica, such as ferulic acid, ligustilide, senkyunolide I, senkyunolide H and butylidene phthalide, can be retained; in addition, the drying technology adopted in the invention is green and free from pollution; the whole angelica roots can be effectively prevented from being mildewed; long-term storage can be easily realized; and the drying technology can be used as the substitute technology for processing whole angelica roots through sulphur fumigation.

Description

technical field [0001] The invention relates to a method for processing Chinese medicinal materials, in particular to a processing method for rapidly drying the whole root of Angelica sinensis for long-term storage. Background technique [0002] Angelica sinensis is the dried root of Angelica sinensis, one of the most commonly used Chinese medicinal materials in my country. Angelica has the functions of invigorating blood and nourishing blood, regulating menstruation, relieving pain, and laxative. It is usually used clinically to treat diseases such as irregular menstruation, anemia, cardiovascular system diseases, and liver fibrosis. In addition, angelica is also a blood-enriching and deficiency-reinforcing Chinese medicine commonly used by the people, and its usage is very large. The main active ingredients in Angelica include phenolic acids and phthalides, of which phenolic acids are mainly ferulic acid, and phthalides are mainly (Z)-ligustilide, (E)-ligustilide esters ...

AI Technical Summary

Problems solved by technology

[0003] The traditional processing method of fresh Angelica sinensis is drying in the shade or drying in the sun. However, the disadvantages of these two methods are that the drying efficiency is too low, the drying time is too long, the drying parameters cannot be controlled, and it is not suitable for the requirements of large-scale industrial production. Mildew and other problems are prone to occur during the drying process

Another commonly used anti-mold and fresh-keeping method is sulfur fumigation. However, modern research shows that sulfur fumigation will cause heavy metal residues and changes in active ingredients in Chinese herbal medicines.
