Abstract

The invention discloses a method for preparing milkvetch root microcapsules. The method comprises the following steps: grinding dried milkvetch root tubers, adding milkvetch root tubers into ethyl alcohol for dissolving, adding 8-12 mass percent of Span emulsifier, and uniformly stirring, thereby obtaining a core material solution; dissolving gelatin and sucrose ester into water, thereby obtaining a wall material solution, wherein the mass ratio of the gelatin to sucrose ester to water is (10-15):(5-10):100; adding the core material solution and the wall material solution into an ultrasonic homogenizer according to a mass ratio of 1:(2-3) and homogenizing for 10-20 minutes; and performing microwave drying on the obtained slurry, thereby obtaining dried powder with the moisture content of 6%-8%, cooling to room temperature, and packaging, thereby obtaining the milkvetch root microcapsules. According to the milkvetch root microcapsules prepared by the method, the active ingredients can be prevented from being isolated from outside, the stability of the milkvetch root is obviously improved, the storage period is obviously prolonged, and full nutrients and active ingredients of the raw milkvetch root powder can be well preserved.

Description

technical field [0001] The invention relates to the technical field of Chinese herbal medicine processing, in particular to a method for preparing astragalus microcapsules. Background technique [0002] Astragalus membranaceus (Fisch.) Bunge. ）， Also known as Mianqi, Astragalus, Duchene, Shuzhi, Baiben, Baiyao cotton, Huangshen, blood ginseng, Renbian and so on. Astragalus contains saponins, sucrose, polysaccharides, various amino acids, folic acid, selenium, zinc, copper and other trace elements. The root of Astragalus membranaceus is used as medicine, which has the effects of invigorating qi, nourishing blood, and benefiting the middle. It is suitable for internal injuries, fatigue, spleen deficiency, diarrhea, qi deficiency, blood deficiency, and qi failure. Sweating, night sweats, stagnation of blood, edema, carbuncle and gangrene without ulceration or ulceration for a long time. [0003] In the prior art, the deep processing of Radix Astragali medicinal material is s...
