Problems solved by technology

[0015] Considering the thermal sensitivity of astaxanthin, the high-pressure homogenization wall breaking method and ultrasonic wall breaking method can lead to the inactivation of astaxanthin due to temperature rise
At present, the method of repeated freezing and thawing is commonly used to break the wall, but the particle size of the algae residue in the repeated freezing and thawing method is small, the slurry is difficult to separate by traditional filtration technology, and there are many impurities in the extract, and the subsequent separation and purification process of macroporous resin is tedious. , many reagents used, difficult recovery of astaxanthin and other problems, it is necessary to develop new extraction and separation methods

Abstract

The invention discloses a method for extracting astaxanthin from haematococcus pluvialis by a double-aqueous-phase coupled wall breaking technology. A double-aqueous-phase separating system is coupled with a freeze-thawing wall breaking technology through experiments, and the processes of wall breaking, extracting and separating are coupled through the introduction of the double-aqueous-phase system. The astaxanthin can be effectively separated from algae residues and various impurity components by a simple liquid separating method during wall breaking and extracting, and the purity and the extracting rate of the astaxanthin are effectively improved. The extracting and separating processes are reduced, and meanwhile, a freeze-thawing agent and an extractant are consistent with the phase forming substances of the double-aqueous-phase system. The types and the dosage of reagents are reduced, and the used reagents are environment-friendly and easy to recycle.

Description

technical field [0001] The invention relates to the technical field of chemical extraction, in particular to a method for extracting and separating astaxanthin from Haematococcus pluvialis using a two-phase coupling wall breaking technology. Background technique [0002] Astaxanthin is the only carotenoid that can pass through the blood-brain barrier. Studies have shown that the antioxidant activity of astaxanthin is more than 10 times higher than that of β2 carotene, and it is also higher than vitamin E in inhibiting lipid peroxidation. More than 100 times, known as "super antioxidant", has been widely used in health food, medicine, cosmetics and aquaculture industry, with extremely high economic value and health care effect. Haematococcus pluvialis is recognized as the best biological source of natural astaxanthin in nature. The astaxanthin content of Haematococcus pluvialis can reach more than 3%, which is much higher than other raw materials. It is extracted from Haemato...
