Description
Technical field
The invention belongs to technical field of bioseparation is and in particular to a kind of extract astaxanthin from haematococcus pluvialis cell
Method.
Background technology
Astaxanthin is 3,3 '-dihydroxy -4,4 '-diketo-β, β '-carrotene, is terpenes unsaturated compounds, is
One Carotenoids.Natural astaxanthin is one of the strongest antioxidant in nature, can oxygen effectively in scavenger-cell from
By base, strengthen cytothesis ability, the accumulation maintaining organism balance and reducing senile cell.The ability of its scavenging activated oxygen is
Ascorbic 6000 times, 700 times of anthocyanidin.Meanwhile, natural astaxanthin be uniquely a kind of can by the class of blood-brain barrier recklessly
Radish element.Since 2008, research discovery both at home and abroad has multiple physiological functions, such as non-oxidizability, antitumor, pre- anti-cancer,
Strengthen immunity, improve the aspects such as eyesight and have certain effect.
The main source of natural astaxanthin is marine products discarded object, phaffiafhodozyma and haematococcus pluvialis.The life of its moderate rain is red
Content astaxanthin in ball algae be far above in addition both, generally up to 1.5%-3%, be referred to as " concentrating of natural astaxanthin
Product ".Therefore, extracting natural astaxanthin from haematococcus becomes the focus of recent domestic research and produces natural astaxanthin
Main method.
Haematococcus pluvialis are subordinate to Chlorophyta, volvocales, haematococcus section, haematococcus, rain non-hibernating eggs.Its cell membrane is thicker, plus
The big difficulty therefrom extracting astaxanthin, by the way of organic solvent directly extracts, the recovery rate of astaxanthin is less than 50%
(CN103044304A), therefore the key that effective broken wall treatment is in Astaxanthin extraction technique is carried out to haematococcus pluvialis cell
Step.
The broken wall mode of existing report mainly includes:1. high-pressure homogeneous broken (CN104961668A).The method sporoderm-broken rate
For 90% about, sample needs through repeated multiple times broken wall treatment, take longer thus leading to effective ingredient oxidized;In addition red
Algae easily settles ball in the solution, leads to feed liquid uneven thus blocking instrument.2. flash extracter (CN105254551A).Should
Method crushing efficiency is not high, and treating capacity is less, and the recovery rate of final products is relatively low.3. high-pressure breaking (CN103787941A).
The method adopts 100-300mPa high pressure to crush, and, more than 95%, effect is preferably but higher to equipment requirement for sporoderm-broken rate, is difficult on rule
Modelling is used in producing.4. acidic treatment (CN103232375A).It is molten as broken wall that the method additionally with the addition of acid in system
Agent, increases the detached difficulty of product, and acid solution is not easy to recycle.5. at glacial acetic acid ice bath, refiner homogenate and liquid nitrogen
Manage the crush method (CN104529852A) that combines.The method sporoderm-broken rate is up to 97.7%, but operation sequence is complicated, relatively costly and
Recovery rate is relatively low, is not suitable for being applied to large-scale production.6. multigelation method (CN104557651A).The method is using addition sulphur
Sour aqueous ammonium multigelation broken wall, freezing and thawing cycle is up to 15-20h, and single broken wall inefficiency is not appropriate for actual production.7.
Ultramicro grinding method.The method belongs to dry grinding category, and broken wall efficiency is preferable, but due to the oily matter in broken rear haematococcus
It is released, lead to feed powder to stick in a large number in equipment kettle and be difficult to shift, have impact on the application of the method.
Content of the invention
The technical problem to be solved is the Astaxanthin extraction providing a kind of brand-new high-efficiency wall breaking to be coupled extraction
Technique.
For solving above-mentioned technical problem, the thinking of the present invention is to be coupled extraction process with wet grinding, using sand mill
Complete the extraction of astaxanthin while to haematococcus breaking-wall cell, feed liquid takes solution to carry out vacuum distillation after separation of solid and liquid and returns
Receive extractant, concentrate peony oil paste and be astaxanthin extract.This technological operation is easy, takes extremely short, and sporoderm-broken rate is high
Reach 99.9%, Astaxanthin extraction rate is up to more than 99%.

The mixture of ratio.Organic solvent preferably these low viscosities, low boiling, the organic solvent of good fluidity.Higher boiling can not be adopted
Solvent or the higher solvent of viscosity or grease type solvent, this class solvent exists and is not easily recycled it is impossible to simple realization separation of solid and liquid
And the shortcoming affecting the content of effective ingredient in final astaxanthin extract.
In step (1), the ratio of haematococcus pluvialis and organic solvent is 1kg:1-10L.
In step (2), described sand mill is excellent pin-type sand mill or turbine type sand mill.
In step (2), described sand mill, in its grinding chamber, filler is ceramic fine bead, and in grinding chamber, microballon loading amount is to grind
The 75%-90% of mill chamber volume.The preferred material of described ceramic fine bead is zirconia ceramics etc., the size of described ceramic fine bead
Preferably diameter 0.5-5mm.
In step (2), described sand mill, grind cavity temperature and control between 10-35 DEG C, preferably 10 DEG C.
In step (2), the milled processed time is 10-600s/L feed liquid.
In step (3), the mode of separation of solid and liquid is centrifugation, plate compression, negative pressure leaching or natural subsidence.
In step (4), the temperature of vacuum distillation is 30-50 DEG C, preferably 40 DEG C.
In step (4), general vacuum distillation is till frozen-free solvent drippage.
In step (4), the organic solvent of recovery is circulated and is mixed with haematococcus pluvialis in step (1).
Beneficial effect:Inventive process have the advantage that:
1. haematococcus cell-wall breaking ratio is high, and while carrying out broken, solvent can directly extract astaxanthin, entirely crushes
It is coupled extraction process and substantially reduces the time-consuming of existing process, be effectively guaranteed the BA of natural astaxanthin.
2. obtained without any other solvent, recycling design in addition to the easy recycling design adding in whole technique
Astaxanthin extract does not have composition that other external sources add it is ensured that the quality of extract and be easy to the exploitation of subsequent product.
3. in whole technique, solvent reclaims the broken extraction process for a new round in addition to a small amount of volatilization completely, does not almost have
Consume.
4. in technique, solvent for use is low viscosity, low boiling, the organic solvent of good fluidity, on the one hand easily broken rear solid
The detached process of liquid, is on the other hand beneficial to the recycling of solvent.
5. grinding is minimum with microballon loss, and whole system operating cost is very low.
