Abstract
The invention discloses a kind of haematococcus pluvialis slurry or the anti-corrosion method of mud, specific method are as follows：The acid-base value that the haematococcus pluvialis that concentration is 3g/L 10g/L are starched is transferred to by pH≤6 by bronsted lowry acids and bases bronsted lowry first, 0.05% 0.5% Common Preservatives are added in then being starched to algae, are well mixed, after 3 days, have no that any bacterium colony is formed, corruption does not foul algae slurry, and microscopy observation finds that frustule does not rupture completely；The anti-corrosion method of the present invention can effectively prevent the corruption fouling in haematococcus pluvialis liquid concentration process and before spray drying, and will not cause the lesion ruptures of frustule, also not interfere with product quality, cost is relatively low, and operating process is simple.
Description
Technical field
The present invention relates to a kind of haematococcus pluvialis slurry or the anti-corrosion method of mud, belong to feed anticorrosion technical field.
Background technology
Astaxanthin (astaxanthin) is a kind of carrotene of oxidation state.Astaxanthin has extremely strong radical scavenging activity
Power and tinctorial property, thus astaxanthin and its derived product in medicine, health products, skin care item and high-end feed additive field
Through having a wide range of applications.
Culture Haematococcus pluvialis production astaxanthin is the main path for producing natural astaxanthin, and the wherein content of astaxanthin is high
It is most potential production astaxanthin new resources, by domestic and international educational circles and the generally pass of business circles up to 2% one the 7% of dry cell weight
Note.The astaxanthin product in haematococcus pluvialis source obtains GMP, FDA and European Union's new resources certification successively.In China, rain gives birth to red ball
Algae was approved to enter new resources catalogue (No. 17 bulletin of the Ministry of Public Health 2010 year) in 2010, therefore in China's haematococcus pluvialis
The astaxanthin product in source possesses great market.
It is the summer especially in high temperature, first heavy because the protein content of haematococcus pluvialis slurry is very high in actual production
Corrupt fouling is easy to after drop and before spray drying, it is effective and simple workable in this stage needs to prevent
Rotten method.
In State Intellectual Property Office's patent library searching, have no and starch corrosion-resistant on haematococcus pluvialis during large-scale production
Patents；Pertinent literature report is not retrieved yet.Investigated according to inventor, during haematococcus following process, Some Enterprises
Using freezer cryopreservation method, although can ensure that algae slurry or algal gel freshness, because operational volume is larger, energy consumption compared with
Height, unnecessary production cost is added, therefore, it is necessary to find a kind of simple to operate, anti-corrosion from practical operation
Effect is good and the less anti-corrosion method of energy consumption.
The content of the invention
The present invention is namely based on above-mentioned problem, there is provided a kind of favorable anti-corrosion effect, the time is long, security is good, and letter
The anti-corrosion method of single easy-operating haematococcus pluvialis slurry or mud.
It is described anti-present invention employs a kind of haematococcus pluvialis slurry or the anti-corrosion method of mud to reach above-mentioned technical purpose
Rotten method is specific as follows：The acid-base value that certain density haematococcus pluvialis are starched is transferred to by bronsted lowry acids and bases bronsted lowry by certain pH value first,
Then a certain amount of Common Preservatives are added in being starched to algae, and both are well mixed.
Preferably as the present invention, the concentration of the haematococcus pluvialis slurry is 3g/L-10g/L.
Preferably as the present invention, the acid-base value of the haematococcus pluvialis slurry is pH≤6.
Further preferably as the present invention, the amount of the Common Preservatives is 0.05%-0.5%.
Further, frond dry weight is starched with algae in the haematococcus pluvialis slurry concentration 3g/L-10g/L, in particular to algae slurry
The ratio of volume.
Preferably as the present invention, the acid that the regulation pH is used can be citric acid, hydrochloric acid, metatartaric acid, lactic acid etc.
One or more kinds of acid not reacted each other therein；The alkali that the regulation pH is used can be hydroxide
One or more kinds of alkali not reacted each other therein such as calcium, potassium hydroxide, sodium hydroxide.
Further, the 0.05%-0.5% refers to the mass ratio of preservative and algae slurry.
Preferably as the present invention, the conventional preservative refers to sodium benzoate, potassium sorbate, natamycin, breast
One or two kinds of food grade preservative not reacted each other above therein such as acid streptococci element.
The anti-corrosion method of the present invention has advantages below compared with common methods：
After anti-corrosion method using the present invention, have the following advantages that：
Algae slurry is tuned into acidity first, tentatively reduces the growth probability and proliferation rate of bacterium, fungi and mould, it is basic herein
It is upper to add a certain amount of inexpensive Common Preservatives, it reduce further the growth probability of mushroom and extend the holding time,
And then corrupt will not be fouled before ensure that algae slurry spray drying, operating process is simple；Compared with traditional freezer cryopreservation method,
Entreprise cost is greatly reduced, is adapted to the enterprise of various scales to use.Used preservative is food-grade, and Product Safety is not
It is impacted.
