[0002] Dendrobium officinale is a traditional precious Chinese medicine in my country, which has been highly praised by medical scientists of all dynasties. Modern research shows that Dendrobium candidum contains a variety of active ingredients such as alkaloids, flavonoids, aromatics, organic acids and polysaccharides, which have immune regulation, hypoglycemic, and anti-inflammatory properties. In recent years, with the development of Dendrobium artificial cultivation industry, the number of Dendrobium officinale products in the market has been increasing. In order to save brewing time and simplify the eating process, many brewing Dendrobium products have been developed on the market, but most of them are super The instant dendrobium powder obtained by micro-grinding is the main one. The dendrobium powder is brewed after ultra-fine grinding, and the dissolution rate of active ingredients is significantly improved, but the sensory effect of ultra-fine powder brewing is not good, and the soup is cloudy and inconvenient to drink.

Abstract

The invention relates to the technical field of dendrobium stem deep processing, in particular to a preparation method of a segment-shaped dendrobium stem brewing tea. The method comprises the following steps: placing plucked fresh dendrobium stems in hot water for blanching, subjecting the dendrobium stems after the blanching to cold treatment at a temperature of 3-5 DEG C, placing the dendrobiumstems after the cold treatment in a soluble iron ion aqueous solution, conducting mechanical stirring, putting the finally obtained stirred dendrobium stems in a lyophilizer for drying, and subjecting the dried segment-shaped dendrobium stems to sterilization under ultrasonic ultraviolet rays, weighing and packaging. After the obtained segment-shaped dendrobium stem brewing tea is brewed with a conventional method, a dissolution rate of effective components is no less than the dissolution rate of the brewed dendrobium stem powder obtained by superfine grinding, and a treatment mode is green and environmentally friendly, and no toxic reagent is used.
