Embodiment 1

[0038] Taking Dendrobium officinale as an example, the specific steps are as follows:

[0039] 1) Take the fresh product of Dendrobium candidum, remove the leaves, take the fresh strips, wash them with cold water, put them into a high-pressure polyethylene bag filled with cold water, and seal them;

[0040] 2) Put cold water into the ultra-high pressure container, put into step 1) the polypropylene bag in which Dendrobium candidum fresh strips are housed, pressurize to 400MPa, hold the pressure for 20s, and release the pressure;

[0041] 3) Take out the fresh strips of Dendrobium candidum treated with ultra-high pressure in step 2), absorb the surface moisture, place them in the cold well of the freeze dryer, spread the material to a thickness of 10 mm, turn on the compressor, and wait until the freeze-drying temperature drops to the eutectic of Dendrobium candidum After pointing, continue to freeze for 1 hour;

[0042] 4) Take out the fresh strips of the quick-frozen Dendrob...

Embodiment 2

[0052] Taking Dendrobium officinale as an example, the specific steps are as follows:

[0053] 1) Take the fresh product of Dendrobium candidum, remove the leaves, take the fresh strips, wash them with cold water, put them into a high-pressure polypropylene bag filled with cold water, and seal;

[0054] 2) Put cold water into the ultra-high pressure container, put into step 1) the polypropylene bag in which fresh strips of Dendrobium candidum are housed, pressurize to 500MPa, keep the pressure for 1min, and release the pressure;

[0055] 3) Take out the ultra-high pressure Dendrobium officinale fresh strips in step 2), absorb the surface moisture, place them in the cold well of the freeze dryer, spread the material to a thickness of 30 mm, turn on the compressor, and continue freezing for 3 hours after the quick-freezing temperature drops to the eutectic point ;

[0056] 4) Take out the quick-frozen Dendrobium candidum in step 3), quickly move it to the top of the cold trap c...

Embodiment 3

[0066] Taking Dendrobium officinale as an example, the specific steps are as follows:

[0067] 1) Take the fresh product of Dendrobium candidum, remove the leaves, take the fresh strips, wash them with cold water, put them into a high-pressure polypropylene bag filled with cold water, and seal;

[0068] 2) Put cold water into the ultra-high pressure container, put into step 1) the polypropylene bag in which Dendrobium candidum fresh strips are housed, pressurize to 300MPa, keep the pressure for 40s, and release the pressure;

[0069] 3) Take out the ultra-high pressure Dendrobium officinale fresh strips in step 2), absorb the surface moisture, place them in the cold well of the freeze dryer, spread the material to a thickness of 15 mm, turn on the compressor, and continue freezing for 2 hours after the quick-freezing temperature drops to the eutectic point ;

[0070] 4) Take out the quick-frozen Dendrobium candidum in step 3), quickly move it to the top of the cold trap chamb...

Abstract

Belonging to the technical field of traditional Chinese medicine processing, the invention discloses a processing method of dendrobium characteristic decoction pieces. The method includes the steps of: 1) taking fresh dendrobium strips, conducting precooling washing, then putting the dendrobium strips in a high pressure resistant ethylene propylene rubber bag, and conducting sealing; 2) putting the ethylene propylene rubber bag loaded with the fresh strips into a cold water holding ultrahigh-pressure container, and carrying out pressurization and pressure maintaining; 3) taking out the fresh dendrobium strips subjected to high pressure in step 2), sucking dry the surface moisture, and placing the fresh strips in a freeze dryer cold trap to perform quick-freezing; 4) subjecting the quick-frozen fresh dendrobium strips of step 3) to vacuum sublimation; 5) beveling the fresh dendrobium strips into slices; 6) placing the slices obtained in step 5) into a cold trap to perform quick-freezing; 7) freeze-drying the quick-frozen dendrobium slices according to a set process; and 8) acquiring the dendrobium characteristic decoction pieces. The method provided by the invention can effectively improve the dissolution rate and dissolution speed of polysaccharide and dendrobine in hot water, and enhances the medicinal value and health care efficacy of dendrobium. A vacuum freeze-drying technology is employed for freeze-drying, and obviously prolongs the shelf life of the dendrobium characteristic decoction pieces.

Description

technical field [0001] The invention relates to a method for processing characteristic decoction pieces of dendrobium, in particular to a method for processing characteristic decoction pieces (very thin slices) of dendrobium by using an ultra-high pressure and freeze-drying process, and belongs to the technical field of agricultural product processing. Background technique [0002] Dendrobium, one of the Orchidaceae plants, as a valuable medicinal material, is mainly distributed in tropical and subtropical Asia, Australia and Pacific Islands. In my country, most of them are distributed in Southwest China, South China, Taiwan and other places. As medicinal materials or food materials, the sources are mostly the fresh or dried stems of Dendrobium nobile and Dendrobium candidum, perennial herbs of Orchidaceae. Dendrobium contains a large amount of dendrobine and polysaccharide mucilage; among them, dendrobine has a certain analgesic and antipyretic effect, which is similar to ...
