AI Technical Summary

Technical Problem

Dendrobium officinale ultrafine powder is prone to absorbing moisture, clumping, and oxidation during storage and consumption, resulting in a poor user experience. It also tends to clump and stick to the sides of the container when brewing, affecting the efficacy of the medicine and the user experience.

Method used

Dendrobium officinale pellets with a D50 particle size of 50~200μm were prepared and coated with an outer coating film. The coated microparticles of Dendrobium officinale were formed by fluidized bed coating method. The outer coating film is composed of polymer materials, which isolates moisture and oxygen from contact, thereby improving the consumption experience and brewing performance.

Benefits of technology

This method improves the stability and user experience of Dendrobium officinale ultrafine powder, avoids clumping and sticking to the wall, ensures the efficacy of the medicine, and has a good taste.

Abstract

The present application relates to the technical field of Dendrobium officinale, and particularly relates to Dendrobium officinale coated microparticles and a preparation method thereof. The present application separates the contact of Dendrobium officinale superfine powder with moisture and oxygen in the air through an outer coating film, reduces moisture absorption and oxidation, makes the property stable, and prevents caking, thereby solving the stability problem of Dendrobium officinale superfine powder, which is easy to absorb moisture and caking, and is easy to oxidize and reduce effectiveness. The Dendrobium officinale coated microparticles have small particle size, no grit feeling in oral administration, ensure the drug administration effect, and have good taking experience. The present application prepares Dendrobium officinale superfine powder into D 50 The present application separates the contact of Dendrobium officinale superfine powder with moisture and oxygen in the air through an outer coating film, reduces moisture absorption and oxidation, makes the property stable, and prevents caking, thereby solving the stability problem of Dendrobium officinale superfine powder, which is easy to absorb moisture and caking, and is easy to oxidize and reduce effectiveness.
