Embodiment 1

[0031] A method for extracting and refining maca polysaccharides, comprising the following steps:

[0032] (1) Extraction: Under the condition of normal temperature and 400Mpa, maca rhizomes are extracted twice with water. The first water consumption is 5 times the mass of maca rhizomes, and the second water consumption is 4 times the mass of maca rhizomes. times, the extraction time was 20min and 25min respectively, combined the extracts, filtered, and the filtrate was the crude extract;

[0033] (2) Concentrating the crude extract: the crude extract is treated with a low-crosslinked polyacrylic acid sodium salt type water-absorbing resin to obtain a concentrated solution whose volume is 1 / 6 of the volume of the crude extract;

[0034] (3) Preliminary removal of impurities by flocculation: adding bentonite to the concentrated solution, stirring for 50 minutes, standing for 2 hours, filtering to remove impurities, and obtaining the filtrate; the mass ratio of the concentrated ...

Embodiment 2

[0038] A method for extracting and refining maca polysaccharides, comprising the following steps:

[0039] (1) Extraction: Under the condition of normal temperature and 200Mpa, maca rhizomes are extracted with water at a mass ratio of 8:1. The extraction time is 30 minutes, extracted twice, combined with the extracts, filtered, and the filtrate for the crude extract;

[0040] (2) Concentrating the crude extract: the crude extract is treated with a low-crosslinked polyacrylic acid sodium salt type water-absorbing resin to obtain a concentrated solution whose volume is 1 / 4 of the volume of the crude extract;

[0041] (3) Preliminary removal of impurities by flocculation: add bentonite to the concentrated solution, stir for 30 minutes, place for 3 hours, filter to remove impurities, and obtain the filtrate; the mass ratio of the concentrated solution to bentonite is 3500:1;

[0042] (4) Secondary removal of impurities by flocculation: under stirring, add the filtrate to the modi...

Embodiment 3

[0045] A method for extracting and refining maca polysaccharides, comprising the following steps:

[0046] (1) Extraction: Under the condition of normal temperature and 300Mpa, maca rhizomes are extracted with water at a mass ratio of 5:1. The extraction time is 25 minutes, extracted three times, combined with the extracts, filtered, and the filtrate for the crude extract;

[0047] (2) Concentrating the crude extract: the crude extract is treated with a low-crosslinked polyacrylic acid sodium salt type water-absorbing resin to obtain a concentrated solution whose volume is 1 / 5 of the volume of the crude extract;

[0048] (3) Preliminary removal of impurities by flocculation: adding bentonite to the concentrated solution, stirring for 40 minutes, standing for 2 hours, filtering to remove impurities, and obtaining the filtrate; the mass ratio of the concentrated solution to bentonite is 3600:1;

[0049] (4) Secondary impurity removal by flocculation: under stirring, add the fil...

Abstract

The invention discloses a method for extracting maca polysaccharide, which comprises the following steps of: (1) leaching: leaching maca rhizome by water under the conditions of room temperature and 200-500MPa to obtain crude extract; (2) concentrating the crude extract; (3) primarily removing impurities by flocculation; (4) secondarily removing impurities by flocculation; and (5) spray drying: spray drying the filtrate obtained in the step (4) to obtain the maca polysaccharide. The method adopts ultrahigh pressure for leaching the raw material, improves the extraction rate by high squeezing action, high permeability and the expansion during pressure relief, and reduces the energy consumption by adopting room temperature leaching. Water-absorbent resin is used for treating the extract, so that the energy consumption is saved, and the defects of difficult filtering and high cost can be overcome. Bentonite and modified starch flocculant are used for removing the impurities, the impurities are completely removed, and the loss of the polysaccharide is low, so that the method is energy-saving, environment-friendly, free from secondary pollution, simple and easy to control in operation and low in production cost. The obtained product is stable in properties and higher in purity.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a method for extracting and refining maca polysaccharide. Background technique [0002] Maca is the radish-like hypertrophic rhizome of the cruciferous plant Maca maca. It is a medicinal and edible plant. It is mainly distributed in Peru and is one of the important food sources for the local Incas. Eating maca can enhance energy, eliminate fatigue, improve fertility, improve sexual function and women's menopause syndrome, etc., so it has the reputation of "South American ginseng". Wherein Maca polysaccharide is the active substance with abundant content in Maca. Maca polysaccharides have different physiological activities (anti-oxidation function, anti-fatigue function, etc.), and have huge development and utilization value. At present, there are many researches on polysaccharides at home and abroad, but there has not been too much research on maca polysaccharides. Re...
