A kind of preparation method of dendrobium instant freeze-dried block

Abstract

The invention discloses a preparation method of dendrobium instant freeze-dried block, which comprises the following steps: (1) washing and cutting fresh dendrobium raw materials; (2) high-speed wall breaking; (3) centrifugal filtration; (4) high-speed dispersion; ( 5) high-pressure homogenization, (6) adding a lyoprotectant; (7) freeze-drying; (8) packaging. The present invention maintains the porous structure by adding excipients, and has better reconstitution and instant dissolution, uniform dispersion, and smooth mouthfeel, so that the Dendrobium instant freeze-dried block prepared by the present invention has a long shelf life, good quality, and is instant at low temperature. It has the characteristics of reconstitution and convenient portability, and has broad market application prospects.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of a dendrobium instant freeze-dried block. Background technique [0002] Dendrobium is a kind of herb belonging to the Orchidaceae (Orchidaceae) genus Dendrobium. The 2015 edition of the Chinese Pharmacopoeia included Dendrobium officinale and Dendrobium (source Dendrobium chinensis, Dendrobium drumstick, Dendrobium tassel).

As one of the traditional precious Chinese medicinal materials, Dendrobium has the reputation of "the first of the nine Chinese immortal herbs" among the people, and it is a precious traditional Chinese medicine with a variety of biologically active s...

AI Technical Summary

Problems solved by technology

Both Xianpin and Fengdou have disadvantages such as inconvenient administration, less dissolution of active ingredients and low bioavailability

Dendrobium contains a large amount of mucopolysaccharide and cellulose components, which are not easy to disperse, and it is easy to stick into agglomerates when mixed with boiling water, which affects its intake.

CN101700361A discloses a kind of Dendrobium candidum instant powder and preparation method thereof, said fresh Dendrobium candidum is added with water to extract juice, then freeze-dried or spray-dried and then added auxiliary materials to prepare Dendrobium candidum instant powder, the method prepares Dendrobium instant powder and its resolubility Low, and bubbling, peeling, and fracture have occurred during the freeze-drying process, which affects its freeze-drying efficiency

CN104056069A discloses a preparation method of a dendrobium broken wall preparation, the broken wall of the dendrobium is crushed and then granulated and dried to obtain a dendrobium broken wall preparation. The preparation is easily sticky when mixed with boiled water, and the solubility is not good

CN104623312A discloses a kind of dendrobium instant powder, its preparation method and application. The fresh dendrobium candidum is homogenized with water, sprayed and dried with auxiliary materials and then granulated to obtain dendrobium instant powder. The higher the volatility of heat-sensitive substances and the loss of active ingredients, the color will change, and the solubility in water is not good enough. In order to keep the original volume and shape of the product after drying, it can be dissolved quickly and completely after adding water. , in the drying process, it is often necessary to add a certain amount of excipients to maintain the porous solid structure of the freeze-dried product
