Embodiment 1

[0036] A kind of drying operation step of Dendrobium Huoshanense stem is as follows:

[0037] Step 1: Preparation of concentrated stock solution of Dendrobium huoshanense

[0038] The fresh stems of Dendrobium Huoshanense with incomplete shape and inferior quality were frozen at -15 °C for 6 h, taken out, and thawed at 25 °C until the tissue was free of ice, and frozen and thawed twice in this way to obtain the frozen-thawed stems of Dendrobium Huoshanense; The frozen and thawed stems of Dendrobium Huoshanense were squeezed at a pressure of 60 MPa and a temperature of 60°C for 5 minutes to obtain the stock solution of Dendrobium Huoshanense. The stock solution of Dendrobium Huoshanense was evaporated and concentrated by a rotary evaporator at a temperature of 55°C and a vacuum of 0.1 MPa until the volume was 40% of the original volume. Huoshan Dendrobium stem concentrated stock solution;

Abstract

The invention relates to a dendrobium huoshanense stem drying method. The method is characterized in that firstly, dendrobium raw liquid is prepared by a repeated freeze thawing tissue wall-braking technology and is concentrated; then, ultrasonic synchronous dehydration degassing combined vacuum infiltration filling is used, so that dendrobium tissues are filled with the concentrated liquid of the dendrobe raw liquid; then, a dendrobe dry product is manufactured through vacuum drying; finally, the long-period storage is reached through composite material nitrogen-filled packing. Compared with the existing drying method, the dendrobium huoshanense stem drying method has the advantages that the dendrobium drying efficiency is improved; the production period is shortened; the concentrated liquid of the dendrobe raw liquid is used as steeping and filling liquid; the eating quality of dendrobium is improved; the effective utilization of dendrobe with defective quality condition is also realized; the obtained dry product has high finished product rate and good reconstitution property; the inherent body morphology, the color and luster and the biological activity of the dendrobium are maintained to the greatest degree; the eating is convenient; the carrying and the storage are convenient; the resource development and the market expansion of the dendrobium are favorably realized.

Description

technical field [0001] The invention belongs to the technical field of processing dendrobium, in particular to a drying method for stems of dendrobium huoshanense. technical background [0002] Huoshan Dendrobium ( Dendrobium huoshanense ), commonly known as rice dendrobium, is a perennial herb of Orchidaceae, mainly produced in Huoshan County, Anhui Province in the Dabie Mountains, and has a long history of food and medicine. Modern research shows that Dendrobium Huoshanense not only contains amino acids, vitamins, proteins and other nutritional components, but also is rich in active factors such as polysaccharides, flavonoids and polyphenols. Among them, polysaccharides, as the main active ingredient of Dendrobium Huoshanense, have many functions such as enhancing the body's immunity, anti-oxidation, anti-tumor, and lowering blood sugar. In recent years, with the success of the artificial cultivation technology of Dendrobium Huoshanense and the improvement of people's li...
