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] Examples of processing methods for the retention of all components of Dendrobium officinale: (please give a specific example to explain the production process, and the parameters should use the actual values ​​during operation)

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

Embodiment 2

[0028] The main component polysaccharide content and in vitro dissolution experiment of Dendrobium officinale granules prepared according to the method of Example 1

[0029] 2.1 Comparison of polysaccharide content in fresh Dendrobium candidum and ultrafine powder

[0030] Weigh two fresh Dendrobium officinale, 600g each. One part is cut into small sections of 2 to 3 cm, and the dried product is vacuum freeze-dried according to the aforementioned process. The medicinal powder with a size of 10 to 80 mesh is crushed by a common grinder, and dried at 60°C under normal pressure to a moisture content of 3% to 10%. Crush with a low-temperature vibrating pulverizer, feed 200~500g, 2~20℃, pulverize for 6~40min, use 40%~90% ethanol to make the superfine powder, pass 10~80 mesh sieve to granulate, 60℃ dry After 2 hours, whole granules to obtain Dendrobium officinale superfine powder granules. Cut the other portion into 1cm pieces, weigh about 2g, accurately weigh it, grind in a mortar, ad...

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 (Dendrobium officinale Kimura et Migo) is a perennial herb of the Orchidaceae plant Dendrobium (Dendrobium). 1. The price is expensive, the ones with sweet taste, heavy quality, flexibility and stickiness are better. It can benefit the stomach and promote fluid, nourish yin and clear away heat. It can be used for yin damage and loss of body fluid, dry mouth and polydipsia, less eating, retching, deficiency and heat after illness, and dark eyes. The traditional method of use is to chew fresh products directly, or choose a single-flavored decoction of Dendrobium candidum, or combine with other medicinal materials to replace tea. The former medicinal materials are fresh products, with complete preservation of nutrients, the nutrients and medicinal functions contained in it are not affected,...
