Abstract

The invention relates to a method for preparing polysaccharide instant powder by extraction, purification and spray drying; the dendrobium officinale polysaccharide is extracted with the ultrasonic assisted negative pressure cavitation method, and NKA-2 macroporous resin is optimized to purify the dendrobium officinale polysaccharide; the spray drying parameters and the formula of the dendrobium officinale polysaccharide are optimized, and an optimization technology of the preparing polysaccharide instant powder is formulated. A set of technology for preparing polysaccharide instant powder by extraction, purification and spray drying of the dendrobium officinale polysaccharide is formulated, compared with traditional methods, the dendrobium officinale polysaccharide is extracted efficiently and rapidly, with the adoption of the preparation technology, the extraction amount, the purity, the deproteinization rate and the depigmentation rate of crude polysaccharide are high, the prepared dendrobium officinale polysaccharide has excellent fluidity, larger stacking density, stable dispersity and rapid solubility and has an important significance for deep processing of the dendrobium officinale polysaccharide.

Description

technical field [0001] The invention relates to a set of techniques for extracting and purifying polysaccharides from dendrobium officinale and making them into instant powder. Background technique [0002] Dendrobium candidum is a famous and precious Chinese medicinal material, and polysaccharide is one of its recognized effective components, and its content in Dendrobium candidum is as high as about 30%. At present, the research on polysaccharides of Dendrobium officinale mainly focuses on its structure analysis and physiological activity screening. However, Dendrobium candidum, as a clear and excellent immunomodulator, is rarely listed on the market for the deep processing of Dendrobium candidum polysaccharides. In order to make full use of the medicinal value of Dendrobium officinale, this patent conducts research on the deep processing of polysaccharides from Dendrobium officinale. An effective extraction process has been developed to efficiently obtain polysaccharide...
