Embodiment 1

[0022] A. The raw material of aloe gel juice is obtained by cleaning, disinfecting, cleaning, squeezing and filtering the aloe leaves, and concentrates 40 tons of aloe gel juice raw materials (0.75% soluble solids, and 4.47% mass ratio of aloe polysaccharides) Until its soluble solids are 19%, then filter and sterilize to obtain 1.5 tons of concentrated aloe gel juice (the detection of aloe polysaccharide is 4.21% mass ratio);

[0023] B. According to the volume ratio of aloe gel concentrated juice: strong acid macroporous cation exchange resin=1.5:1, the aloe gel concentrated juice obtained in step A is passed through a commercially available industrial grade strong acid macroporous cation exchange resin column, and the contact time is controlled to be 25min , to obtain the aloe vera gel juice Ⅰ without protein and amino acid;

[0024] C. According to the volume ratio of aloe gel juice I: macroporous anion exchange resin=1:1, the aloe gel juice I obtained in step B is passed ...

Embodiment 2

[0030] A. Obtain the aloe gel juice raw material by cleaning, disinfecting, cleaning, squeezing, and filtering the aloe leaves, and concentrate 25 tons of the aloe gel juice raw material (the soluble solids are 1.0%, and the detected aloe polysaccharide is 4.8% mass ratio) to The soluble solid content is 20%, and then filtered and sterilized to obtain 1.2 tons of concentrated aloe gel juice (the detection of aloe polysaccharide is 4.53% by mass);

[0031] B. According to the volume ratio of aloe gel concentrated juice: strong acid macroporous cation exchange resin=1:1, the aloe gel concentrated juice obtained in step A is passed through a commercially available industrial grade strong acid macroporous cation exchange resin column, and the control contact time is 25min , to obtain the aloe vera gel juice Ⅰ without protein and amino acid;

Embodiment 3

[0038] A. The raw material of aloe gel juice (0.5% soluble solid content) is obtained by cleaning, disinfecting, cleaning, squeezing, and filtering the aloe vera leaves, and the raw material of aloe gel juice is concentrated to 18% of its soluble solid content, and then filtered , sterilizing and preparing concentrated aloe gel juice;

[0039] B. According to the volume ratio of aloe gel concentrated juice: strong acid macroporous cation exchange resin=5:1, the aloe gel concentrated juice obtained in step A is passed through a commercially available industrial grade strong acid macroporous cation exchange resin column, and the contact time is controlled to be 20min , to obtain the aloe vera gel juice Ⅰ without protein and amino acid;

[0040] C. According to the volume ratio of aloe gel juice I: macroporous anion exchange resin=2:1, the aloe gel juice I obtained in step B is passed through a commercially available industrial grade macroporous anion exchange resin column, and t...

Abstract

The invention provides a refining method of an aloe polysaccharide having high content and high purity. An aloe gel juice raw material is concentrated until the soluble solid matter concentration is 18-22%, and an aloe gel concentrated juice is prepared by filtering and sterilizing; after the obtained aloe gel concentrated juice is subjected to three-grade ion exchange adsorption, refining of the aloe polysaccharide is completed, and a juice or a dried power of the aloe polysaccharide having high content and high purity is obtained by conventional treatment. The method is easy to operate and control, the polysaccharide purity is high, the content reaches more than 30%, used resin can be recycled, the environmental pollution is decreased, and the production cost is reduced; and at the same time, because the resin has specificity, the contact time is short, the polysaccharide has basically no loss, and economic benefits and social benefits are quite good.

Description

technical field [0001] The invention relates to a method for refining aloe polysaccharides, in particular to a method for refining aloe polysaccharides with high content and high purity, and belongs to the technical field of plant processing. Background technique [0002] Aloe is an evergreen herb of Liliaceae and Aloe. It is native to the Mediterranean coast, Africa, and tropical America. It is also distributed in Yunnan, my country. Aloe vera is an ancient and traditional traditional Chinese medicine. No matter in traditional medicine or modern medicine, the medicinal value of aloe vera has been affirmed. This is clearly recorded in the early medical books and modern pharmacopoeias of our country. In recent years, aloe has been widely used in cosmetics, food, health products and other fields. Although our country is not as good as developed countries in terms of in-depth research, application and industrialization of aloe, it has also made great progress in recent years, ...
