Embodiment Construction

[0010] Take 2000 kg of aloe vera gel juice in the mixing tank, add 0.01% or 0.2 kg of cellulase, stir evenly, keep warm at 40°C for half an hour, and then use a pump to inject 0.22u microporous membrane modules for microfiltration and microfiltration of the dialysate After filtering through the ultrafiltration membrane, when the ultrafiltration concentrate is 100 kilograms, stop the ultrafiltration assembly, put 100 kilograms of concentrated juice into a 1.5 ton mixing tank, add 1000 kilograms of 95% ethanol, stir for 5 minutes, and let stand for 3 hours. Then filter with a filter, recover ethanol, transfer the precipitate to a 100L stirring tank, wash the filter cloth 3 times with water, transfer the washing water to the stirring tank, add water to 50L, and then concentrate with a small ultrafiltration membrane module, when the concentrated solution is 10L When the operation is stopped, the pure aloe acetylated glucomannan concentrate is collected. 10L of concentrated juice w...

Abstract

A separation and purification process of acetylated aloe glucomannan from aloe juice includes adding special biochemical enzyme to aloe juice straining and ultrafiltering to obtain concentrated aloe juice; adding organic solution to concentrated aloe juice to extract coarse aloe polysaccharide, water washing and filtering; ultrafiltering and concentration to obtain water solution o purified acetylated aloe glucomannan; and freeze drying to obtain powder. The said process combines separation and concentration, maintains the activity of acetylated aloe glucomannan, and can be used in industrialproduction.

Description

technical field [0001] The invention relates to the application of biotechnology and membrane technology in the extraction process of aloe acetylated glucomannan. technical background [0002] Aloe extract is an important raw material in medicine, food, chemical industry, etc. Aloe acetylated glucomannan is one of the important functional components in aloe extract, which has the functions of enhancing immunity, anti-aging, preventing cancer, healing wounds, and anti-radiation and other effects. However, the content of acetylated glucomannan is low, so it is very difficult to extract, separate and purify. In the laboratory, crude polysaccharides are extracted by ethanol precipitation, separated by glucose gel, and concentrated. It is very difficult to extract, separate and purify in industrial production, and it has not been reported so far. Improving the extraction, separation and purification of aloe polysaccharides is a necessary condition for mass production of high-q...
