A method for producing broken-wall Haematococcus pluvialis powder
A technology of Haematococcus pluvialis powder and Haematococcus pluvialis, which is applied in the directions of microorganism-based methods, biochemical equipment and methods, and microorganism dissolution, etc., can solve the problem that the liquid nitrogen grinding method is not suitable for large-scale industrial production, and the It is difficult to improve the wall rate and the use conditions are harsh, so as to achieve the effects of extending the operation cycle and service life of the equipment, reducing the oxidation loss and reducing the homogenization pressure.

Embodiment 1
[0026] Weigh 8kg of Haematococcus pluvialis mud, the water content is 53%, the dry matter astaxanthin content is 5.1%, add hydrochloric acid to make the acid solution 0.2%, stir evenly and place it for 30min; filter the material solution through plate and frame to remove acid Add 20kg of ethanol solvent to the algae mud, stir evenly, break the wall once through a homogenizer, and the pressure is 30MPa; remove the solvent by distillation under reduced pressure to obtain 3.72kg of broken-wall algae powder with an astaxanthin content of 5.0%, measured The wall breaking rate was 98.5%, and the astaxanthin content recovery rate was 97.0%.
Embodiment 2
[0028] Weigh 20kg of Haematococcus pluvialis mud, the water content is 47%, the dry matter astaxanthin content is 3.50%, add phosphoric acid to adjust the solution concentration to 1%, stir evenly and place it for 60 minutes; filter the material solution through a plate frame to remove the acid solution , add 35 kg of ethyl acetate solvent to the algae mud, stir evenly, and remove impurities by passing through an 80-mesh screen; the wall is broken by a homogenizer, and the pressure is 35 MPa, and the number of times is 1; after standing to be separated, remove 7 kg of the upper solvent, The solvent was removed by distillation under reduced pressure in the lower layer to obtain 9.21 kg of broken Haematococcus pluvialis powder with an astaxanthin content of 3%, and the measured breaking rate was 99.3%. The separated upper solvent was filtered and vacuum distilled to obtain 1.34 kg of astaxanthin oil with a content of 6.1%, and the yield of astaxanthin was 96.5%.
Embodiment 3
[0030] Weigh 20kg of Haematococcus pluvialis mud, the water content is 53%, the dry matter astaxanthin content is 3.70%, add oxalic acid to adjust the solution concentration to 0.01%, stir evenly and place it for 20 minutes; filter the material liquid through a plate frame to remove Acid solution, add 28.2kg of ethyl acetate solvent to the algae mud, stir evenly, and remove impurities through a 80-mesh screen; break the wall with a homogenizer, the pressure is 20MPa, and the number of times is 1; after standing for stratification, remove 7.5 kg upper layer solvent, and the lower layer decompressed distillation to remove the solvent to obtain 8.05 kg of broken Haematococcus pluvialis powder with an astaxanthin content of 3.2%, and the measured breaking rate was 98.7%. The separated upper solvent was filtered and vacuum distilled to obtain 1.3 kg of astaxanthin oil with a content of 6.2%, and the yield of astaxanthin was 97.24%.
