Problems solved by technology

[0004] Bletilla striata polysaccharides are usually extracted by hot water or ethanol. Due to the viscosity and water swelling properties of Bletilla striata polysaccharides, it is necessary to add new extraction solvents or increase extraction batches in time during the extraction process. The production cycle is long, the amount of solvent is large, and energy consumption is high. Higher, the purity of bletilla striata polysaccharide in the prepared product is generally lower than 80%, needs to adopt measures such as multiple ethanol precipitation, ethyl ether and acetone organic solvent washing etc. to improve its purity

Embodiment 1

[0032] Preparation of Bletilla striata crude polysaccharide:

[0033] Main equipment: universal pulverizer, stirring and mixing tank, high-pressure homogenizer, three-legged centrifuge, diatomaceous earth filter, 500+200nm ceramic membrane filter, alcohol precipitation tank, vacuum drying oven.

[0034] Raw materials: Baiji decoction pieces 5kg.

[0035] Preparation Process:

[0036] 1. Pulverization: Pulverize the decoction pieces of Bletilla striata with a universal pulverizer pre-installed with a 1.2mm sieve, so that all of them pass through the No. 2 sieve to obtain coarse powder of Bletilla striata.

[0037] 2. Mixing: mix bletilla striata coarse powder with 500kg20? The primary reverse osmosis water was placed in a stirring mixing tank together, and stirred for 15 minutes, so that the mixture was evenly mixed into a suspension of Bletilla striata.

[0038] 3. Homogenization: input the bletilla striata suspension into a high-pressure homogenizer, and adjust the pressur...

Abstract

The invention mainly relates to a low-temperature preparation method for bletilla polysaccharide, in particular to a process combination for preparing high-purity bletilla polysaccharide at a low temperature by adopting a core process of homogenization-based extraction and ceramic membrane micro-filtration concentration and using water as a solvent.

Description

technical field [0001] The invention mainly relates to a low-temperature preparation method of bletilla striata polysaccharide, in particular to a process combination based on homogenization extraction combined with ceramic membrane microfiltration concentration as the core process for low-temperature preparation of bletilla striata polysaccharide. Background technique [0002] Bletilla striata (Thunb.) Reichb.f is a plant of the genus Bletilla striata in the family Orchidaceae, also known as small bletilla striata, lotus and grass, xuerumo, etc. It has been used as traditional Chinese medicine for thousands of years, and its main function is to astringe sores and stop bleeding , Invigorate the lungs, reduce swelling and promote muscle growth, etc. Bletilla striata bulbs contain a large amount of aqueous polysaccharides, and its chemical composition is glucomannan, which is the main functional component of Bletilla striata. [0003] Bletilla striata gum with a polysaccharid...
