Abstract

The invention discloses eucommia ulmoides male flower instant powder as well as a preparation method and an application thereof. The preparation method comprises the following steps: S1, pretreating eucommia ulmoides male flowers; S2, preparing a eucommia ulmoides male flower extracting solution, namely mixing eucommia ulmoides male flowers with water, adding a natural antioxidant, and performingultrasonic crushing treatment to obtain the eucommia ulmoides male flower extracting solution; S3, performing vacuum concentration on the eucommia ulmoides male flower extracting solution, performingfiltering on the eucommia ulmoides male flower extracting solution, performing vacuum concentration treatment on the filtrate, and performing concentrating until the solid concentration is 75-80% to obtain a concentrated extracting solution; and S4, freeze-drying the concentrated extracting solution, namely performing pre-freezing treatment on the concentrated extracting solution, and then performing vacuum freeze-drying treatment to obtain the eucommia ulmoides male flower instant powder of which the water content is lower than 5%. According to the eucommia ulmoides male flower instant powderobtained through the preparation method, fresh eucommia ulmoides male flowers are prepared into the eucommia ulmoides male flower instant powder, the storage life of the eucommia ulmoides male flowerinstant powder is effectively prolonged, and original nutritional and active ingredients of the eucommia ulmoides male flowers are well reserved.

Description

technical field [0001] The invention relates to the field of eucommia male flowers, in particular to an instant powder of eucommia male flowers. In addition, the present invention also relates to a preparation method and application of the above-mentioned eucommia male flower instant powder. Background technique [0002] Eucommia is a rare and precious medicinal plant unique to my country. At this stage, the research on Eucommia mainly focuses on the cultivation of Eucommia, the processing of Eucommia leaves, seeds and skins, etc. There are relatively few studies on the processing of Eucommia male flowers. Eucommia is dioecious, and Eucommia Male flowers are the flowers of Eucommia male tree. Modern research shows that Eucommia male flowers are rich in lignans, iridoids, phenylpropanoids, flavonoids and other medicinal ingredients similar to Eucommia bark and leaves. Antihypertensive, hypolipidemic, anti-tumor, antibacterial, anti-viral, anti-fatigue, liver protection and gal...
