Problems solved by technology

With the advancement of culture technology, the content of astaxanthin has increased significantly, breaking through 5%, and even reaching more than 6%. The theoretical output of astaxanthin has doubled, but the higher the content of astaxanthin, the more the In order to better protect themselves, the cell cellulose increases, the thicker and tougher the cell wall has reached 6-8 microns, and it is more difficult to break. The rate of cell breakage directly affects the extraction rate of astaxanthin, directly affecting the actual output. If the general method of breaking the wall is used, such as freeze-thaw method, ultrasonic method, biological enzymatic hydrolysis method, high-pressure homogenizer, colloid mill, etc., one or more confluences are used to break the wall, and the breaking rate can only reach 80-85%. , so the wall-breaking technology has seriously restricted the large-scale development of Haematococcus pluvialis cultivation and the expansion of the subsequent astaxanthin industry chain. Now it has become the most breakthrough core issue of Haematococcus pluvialis development technology

Abstract

The invention belongs to the technical field of microalgae microorganisms and relates to a wall-breaking method for haematococcus pluvialis cells which are rich in a biological active substance: astaxanthin. The wall-breaking method for the haematococcus pluvialis cells provided by the invention comprises the following three steps: 1, freezing and ice-crystallizing the haematococcus pluvialis cells and dispersing the cells in a flowing liquid below 0 DEG C; 2, adding a bioactive component which protects the haematococcus pluvialis into the liquid before the ice-crystallized algae cells are broken so as to reduce a protectant which is oxidized and decomposed after wall breaking; and 3, after uniformly grinding by a colloid mill, carrying out ultra-high-pressure wall-breaking by using an ultra-high-pressure homogeneous nanometer machine. The wall-breaking process provided by the invention is carried out under a condition of low-temperature, cold chain and close away from light and breaks walls by means of the characteristic of nanometer crushing by using the ultra-high-pressure homogeneous nanometer machine and has the advantages of rapidness, efficiency and no addition of foreign matters and can be used for effectively protecting the bioactive component.

Description

technical field [0001] The invention belongs to the field of microalgae biotechnology, and in particular relates to the technology for breaking the cell walls of Haematococcus pluvialis cells rich in astaxanthin bioactive substances. Background technique [0002] Haematococcus pluvialis is a single-celled green algae that lives in fresh water. Under certain conditions, it can accumulate a large amount of carotenoids, of which more than 80% are astaxanthin and esters. Astaxanthin has important physiological and biological functions such as anti-oxidation, anti-tumor and increasing immunity. [0003] Haematococcus pluvialis cells have cellulosic cell walls, the cell wall thickness is generally 3-5 microns, and the texture is tough. With the advancement of culture technology, the content of astaxanthin has increased significantly, breaking through 5%, and even reaching more than 6%. The theoretical output of astaxanthin has doubled, but the higher the content of astaxanthin, t...
