Problems solved by technology

Natural astaxanthin has important medical and health value. At present, the content of natural astaxanthin in Haematococcus pluvialis is the highest. However, due to its thick cell wall, it is difficult for the solvent to penetrate into the cell and it is difficult to extract directly.
The traditional wall-breaking process uses water or edible oil as a homogeneous medium. After the wall is broken, it needs to be spray-dried to remove water. The process is cumbersome, the loss of astaxanthin is large, and the yield is low. Generally, the yield does not exceed 80%.

Abstract

The invention relates to a method for quickly extracting astaxanthin from haematococcus pluvialis. The method includes particular technologies of adding organic solvents into haematococcus pluvialis powder, mixing the organic solvents with the haematococcus pluvialis powder to obtain suspension liquid, feeding the suspension liquid into explosion-proof type high-pressure homogenizers and carrying out wall breaking-extraction on the suspension liquid; separating wall-broken haematococcus pluvialis powder from the solvents to obtain astaxanthin extraction liquid and haematococcus pluvialis residues; concentrating the astaxanthin extraction liquid under the protection of inert gas and removing solvent residues to obtain the astaxanthin. The method has the advantages that the effective content yield can reach 90% at least, technological processes are short, operation is simple and speedy, and industrial production can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of extracting and refining natural components, and in particular relates to a method for rapidly extracting astaxanthin from Haematococcus pluvialis. Background technique [0002] Astaxanthin has anti-oxidation, coloring, anti-cancer and immune-enhancing functions, especially its super anti-oxidation function. It is known as "super antioxidant" and has broad application prospects. Natural astaxanthin has important medical and health value. At present, the content of natural astaxanthin in Haematococcus pluvialis is the highest. However, due to its thick cell wall, it is difficult for the solvent to penetrate into the cell and it is difficult to extract directly. The traditional wall-breaking process uses water or edible oil as a homogeneous medium. After the wall is broken, it needs to be spray-dried to remove water. The process is cumbersome, the loss of astaxanthin is large, and the yield is low. Generally...
