Description

Device for extracting astaxanthin from haematococcus pluvialis

Technical Field

The utility model relates to the technical field of astaxanthin extraction, in particular to a device for extracting astaxanthin from haematococcus pluvialis.

Background

Astaxanthin is a main carotenoid component in aquatic organisms in nature and has important significance for the life activities of the aquatic organisms. Like most animals, human beings cannot synthesize carotenoid substances in vivo, but can only obtain the carotenoid substances through food intake, and the astaxanthin is contained in aquatic products such as shrimps, crabs, certain cold water fishes and the like, so that the carotenoid substances become animal sources for supplementing the carotenoid. Astaxanthin is a carotene in an oxidation state, and researches show that the astaxanthin has the antioxidant capacity which is 500 times that of vitamin E and more than 11 times that of carotene, and has obvious effects of resisting oxidation and eliminating active singlet oxygen.

Haematococcus pluvialis is a special fresh water unicellular green algae, can accumulate a large amount of carotenoid under specific conditions, and has the content of 1.5% of the dry weight of cells. In the current industry, the method for extracting astaxanthin from haematococcus pluvialis mainly adopts a chemical solvent extraction method, and the extractant mainly adopts methanol, ethanol, acetone, chloroform and the like. Meanwhile, in order to improve the extraction efficiency of the astaxanthin, the haematococcus pluvialis is subjected to pretreatment such as crushing or wall breaking before the astaxanthin is industrially extracted, and the treatment method is generally a mechanical wall breaking mode such as crushing by a bead mill. However, the organic solvent used in the extraction has certain toxicity, the extraction process is easy to explode, and the organic solvent residues in the extract are easy to cause harm to human bodies. The mechanical wall breaking modes such as the wall breaking of the bead mill have the defects of long wall breaking time, low wall breaking rate, large noise pollution and the like, and the temperature rising phenomenon exists in the mechanical treatment process, so that astaxanthin is easy to inactivate and the active components are reduced.
