Problems solved by technology

The traditional processing methods of Dendrobium officinale are: for fresh use, remove fibrous roots and impurities, due to high storage temperature and humidity requirements, this method is not conducive to the preservation and reprocessing of fresh products; for dry use, remove the roots and wash, dry or Drying, or cutting off part of the fibrous root, twisting it into a spiral or spring shape while frying, and drying it into a tin maple bucket. This traditional processing method will reduce the content of active ingredients in Dendrobium candidum due to heating and human factors. and cause the material to shrink, destroying cells

Embodiment 1

[0023] An example of the processing method of Dendrobium candidum with all components preserved: (please give a specific example to illustrate the production process, and the parameters should use the values ​​​​during actual operation)

[0024] Take fresh Dendrobium officinale to remove fibrous roots and impurities, wash it, wipe off the film on the epidermis, cut it into 3cm pieces, weigh 1000g, put it in a quick freezer for 4 hours, and lower the temperature to -80°C to freeze it all. The temperature of the cold trap drops to -40°C and starts vacuuming. When the vacuum degree drops to 25Pa, the temperature of Dendrobium officinale is lower than -40°C during the sublimation process, and the sublimation is dried for 38 hours. When the vacuum pressure drops to 10Pa, the sublimation is dried. The process is over; continue to set the plate temperature to 25°C, vacuumize, and analyze for 12 hours. The freeze-dried medicinal materials are generally crushed through a 20-mesh sieve,...

Embodiment 2

[0028] Main component polysaccharide content and in vitro dissolution test in Dendrobium officinale granules prepared by the method of Example 1

[0029] 2.1 Comparison of polysaccharide content between fresh Dendrobium officinale and ultrafine powder

[0030] Take by weighing two portions of Dendrobium candidum fresh product, each portion 600g. One part is cut into 2-3 cm sections, and the dried product is vacuum freeze-dried according to the above-mentioned process, pulverized by an ordinary pulverizer to obtain a medicinal material powder between 10-80 meshes, and dried at 60° C. under normal pressure until the water content is 3%-10%. Crush with a low-temperature vibrating pulverizer, feed 200-500g, 2-20°C, crush for 6-40 minutes, use 40%-90% ethanol as a soft material, granulate through a 10-80 mesh sieve, and dry at 60°C After 2 hours, the grains were granulated to obtain the superfine powder particles of Dendrobium candidum. The other portion was cut into 1cm sections...

Abstract

The invention provides a processing method capable of reserving all components of dendrobium candidum. The processing method comprises the following steps: (1) preliminarily processing the medicinal material; (2) freeze-drying in vacuum; (3) preparing common powder; (4) preparing ultrafine powder; and (5) preparing ultrafine particles, wherein the step of freeze-drying in vacuum comprises the following three processes: pre-freezing; sublimation drying; and desorption drying. The product produced by the method has the advantages of fresh color, aromatic flavor and fully reserved nutrient components without loss, and is convenient to serve; meanwhile, the product is thoroughly dewatered, thus being convenient for long-term preservation, reprocessing and transportation at normal temperature.

Description

【Technical field】 [0001] The invention relates to a processing method for retaining all components of Dendrobium officinale. 【Background technique】 [0002] Dendrobium officinale Kimura et Migo is a perennial herb of the genus Dendrobium in the family Orchidaceae. First, the price is expensive, and the sweet, heavy, flexible and viscous ones are the best. It has the functions of benefiting stomach and promoting body fluid, nourishing yin and clearing away heat, and is used for yin injury and body fluid loss, dry mouth and polydipsia, retching due to lack of food, asthenia heat after illness, and blurred vision. The traditional method of use is to chew the fresh product directly, or choose Dendrobium candidum to decoct with a single flavor, or mix it with other medicinal materials to replace tea. The former medicinal material is a fresh product, which has the advantages of complete preservation of nutritional components, the contained nutritional components and medicinal fu...
