Abstract

The invention relates to an extract of Haematococcus pluvialls and a preparation method thereof. After mixing Haematococcus pluvialls powder and a subcritical extraction solvent, continuous subcritical extraction is carried out, and a subcritical extract of Haematococcus pluvialls is obtained after the extraction is completed , collect the subcritical extract, carry out continuous supercritical carbon dioxide extraction treatment to remove the residual solvent in the extract, and obtain the Haematococcus pluvialis extract; it is also possible to carry out thin film evaporation after supercritical desolventization to further Further desolvation. The method of the invention is low in equipment price, easy to operate, relatively complete in removing residual solvents, and high in yield, and is suitable for large-scale production of Haematococcus pluvialis extracts; the temperature and pressure of continuous supercritical desolventization are relatively low, and the extracts are not easily damaged and the solvent removal is relatively complete, so that the astaxanthin content in the obtained Haematococcus pluvialis extract is >8wt%, and the residual butane is <1ppm.

Description

technical field [0001] The invention relates to the technical field of preparation of Haematococcus pluvialis extract, in particular to a Haematococcus pluvialls extract and a preparation method thereof. Background technique [0002] Haematococcus pluvialis is a single-celled green algae that can accumulate a large amount of astaxanthin under adverse conditions, and is recognized as the main source of astaxanthin in nature. Using supercritical fluid CO 2 Technology's Haematococcus pluvialis extract is rich in vitamin B in addition to the natural antioxidant astaxanthin 1 , B 2 , B 6 , B 12 , monounsaturated fatty acids, unsaturated fatty acids and other essential nutrients for the human body. [0003] The extraction methods of Haematococcus pluvialis include solvent method, supercritical method, microwave method, ultrasonic method, etc., but microwave method and ultrasonic method are rarely used in large-scale production. Since astaxanthin oil is the main functional su...
