Description
The present invention relates to the natural product extraction production technique.Particularly, the present invention relates to new carrageenin production method.More specifically, the present invention relates to a kind of method of new production κ, ι-mixed type carrageenin.
Carrageenin has another name called carrageeman, carrageenin, is the Sargassum polysaccharides that a class is extracted from marine red alga, and its chemical structure is D-semi-lactosi and 3, and the linear polysaccharide compound that 6-dehydration-D-galactose residue is formed has ester formula sulfate group on the residue.The carrageenan molecule weight range is between 10,000 to 1,000,000, and great majority are between 100,000 to 500,000.Since its have gel and water-retentivity, thickening and suspending, with premium properties such as combination of proteins, obtained widespread use in a lot of fields.
Different according to the arrangement position of sulfate group in the carrageenin and quantity can be divided into carrageenin κ, ι substantially, go into the three major types type, and they derive from different marine algas respectively.That commonly used is κ-type, ι-type carrageenin.κ-type generally derives from Eucheuma striatum, and ι-type generally derives from agar.
The performance of dissimilar carrageenins is variant slightly.In general, κ-type can form hard gel, but easy bleeding.ι-type gel-strength a little less than, but elasticity is better, not bleeding.
Aspect production technique, the extraction process of pure κ-type carrageenin has utilized it to form the characteristic of hard gel and easy bleeding, and the squeezing of the moisture in the gel is removed, and obtains the solid dry product, and production cost is lower.And pure ι-type carrageenin can only be taked the method for organic solvent deposit, cost higher (" food glue and industrial glue handbook, the Fujian People's Press, 1986 years).Although the agar price is lower than Eucheuma striatum, pure ι-type carrageenin production cost is still 2-3 times of pure κ-type carrageenin.
In actual use, need to use κ, ι-mixed type carrageenin sometimes, to obtain the preferable gel of use properties.In practice, people often mix the back use with pure κ-type carrageenin and ι-type carrageenin, because the high problem of cost is difficult to obtain practical application always.
Therefore, this area presses for the method for preparing κ, ι-mixed type carrageenin that cost is low and/or efficient is high.
Purpose of the present invention just provides the method for preparing κ, ι-mixed type carrageenin that a kind of cost is low and/or efficient is high.
The present inventor finds through going deep into extensive studies for many years, by κ-type carrageenin raw materials for production and ι-type carrageenin raw materials for production are mixed by suitable proportion, and the concentration of control salt can directly make κ, ι-mixed type carrageenin in production technique.Finished the present invention on this basis.
On the one hand, the invention provides a kind of κ-, the production method of ι-mixed type carrageenin, it may further comprise the steps:
(a) with κ-type carrageenin raw materials for production and ι-type carrageenin raw materials for production with 10: 1-2: 3 mixed form and mix raw materials for production;
(b) these mixing raw materials for production that step (a) is formed carry out alkaline purification, thereby make the gel-strength raising and remove the marine alga stink smell;
(c) marine alga after the alkaline purification is boiled glue and handle, thereby make the insoluble component separating of water such as glue branch and Mierocrystalline cellulose, wherein adding concentration in boiling the glue process is the inorganic salt of 2.5-10%;
(d) allow the glue after filtering cool off, thereby obtain the carrageenin gel;
(e) the carrageenin gel is squeezed processing, thus make κ-, ι-mixed type carrageenin.
In the present invention, " κ-type carrageenin raw materials for production " refers to contain κ-type carrageenin effective constituent, and can be used as the raw materials for production of producing κ-type carrageenin in carrageenin production.A kind of typical κ-type carrageenin raw materials for production are Eucheuma striatum.
In the present invention, " ι-type carrageenin raw materials for production " refers to contain ι-type carrageenin effective constituent, and can be used as the raw materials for production of producing ι-type carrageenin in carrageenin production.A kind of typical κ-type carrageenin raw materials for production are agars.
In the present invention, at first κ-type carrageenin raw materials for production and ι-type carrageenin raw materials for production are mixed formation " mixing raw materials for production ".In the present invention, term " mixing raw materials for production " refer to κ-type carrageenin raw materials for production and ι-type carrageenin raw materials for production mix that the back forms, contain the raw materials for production of κ-type carrageenin and ι-type carrageenin effective constituent simultaneously.Generally, mix raw materials for production and should only contain κ-type carrageenin and ι-type carrageenin, and do not contain or only contain the carrageenin of a small amount of other types.Yet, if desired, in mixing raw materials for production, also can contain a small amount of (usually less than 5% (weight), preferably less than 3% (weight), more preferably less than the raw material of other carrageenins of production (as λ-type carrageenin) of 1% (weight)).
The blending ratio of κ-type carrageenin raw materials for production and ι-type carrageenin raw materials for production is vital for the inventive method.Generally, the blending ratio of κ-type carrageenin raw materials for production and ι-type carrageenin raw materials for production is about 10: 1-2: between 3, preferably be about 8: 1-2: between 3.For example, the consumption of κ-type carrageenin raw materials for production (as Eucheuma striatum) by the gross weight of mixing raw materials for production, is 40% to 90%.And the consumption of ι-type carrageenin raw materials for production (as agar) by the gross weight of mixing raw materials for production, is 10% to 60%.
With Eucheuma striatum and agar is example, and their rate of gum output are basic identical, so the ratio of Eucheuma striatum of doing and agar weight is the ratio of κ-type in the mixed type carrageenin, ι-type weight.If Eucheuma striatum is different with the agar ratio, the easy degree of squeezing water outlet can change, and agar content is high more, difficult more squeezing water outlet.At pressure is 5-15 kilogram/cm
2Under the condition, the squeezing time needs 3-8 hour.If it is about 10% that agar content is lower than, then bleeding does not have to change substantially; If it is about 60% that agar content is higher than, then be difficult to the squeezing water outlet.So agar content is to be advisable at about 10%-60%.
In the present invention, to boil in the glue concentration of salinity be to implement another key feature of the present invention in control.In the present invention, boil that should to add concentration in the glue process be 2.5-10%, preferably the inorganic salt of 3-8% (by weight percentage).
When boiling glue control salt concn, can in gel, increase the content of salt, thereby make the easy water outlet of gel.Especially potassium ion can also improve the gel-strength of carrageenin.The present invention is by adding a large amount of salinities (as Repone K) (concentration reaches 2.5-10%, and 3-8% preferably is different and change to some extent with agar content) in boiling the glue process, thereby the squeezing water outlet can be carried out smoothly.Along with moisture is deviate from from carrageenin, excessive salinity also can flow out thereupon.
Be applicable to that salt of the present invention can be any food processing field inorganic salt commonly used.Preferably, this salt is after being dissolved in the water, and the pH value is neutral or near neutral (as pH6.5-7.5).More preferably, this salt is by strong acid and the formed salt of highly basic.Representational example comprises (but being not limited to): Repone K, sodium-chlor, vitriolate of tartar, saltpetre and their mixture.
In the methods of the invention, except raw material and boil in the glue control salt concn with prior art different, other steps all can be carried out according to the ordinary method in production κ-type carrageenin field.For example alkali treatment, Gel Treatment step, squeezing treatment step etc.(description of κ-type carrageenin manufacturing condition, can referring to Shi Guanghan etc., " marine alga processing technology ", agriculture press, 1996 years).
In example of the present invention, adopt in advance and mix Eucheuma striatum and agar by suitable proportion, through following common processes processing, directly make κ-, ι-mixed type carrageenin:
1. take by weighing exsiccant Eucheuma striatum and agar, wherein the agar weight percent is 10% to 60%.
2. will mix to soak in the dish immersion alkali lye and carry out alkaline purification, to improve gel-strength and to remove the marine alga stink smell.Treatment condition are: the system gross weight of accounting for is: Eucheuma muricatum (Gmel.) Web 10-15%, sodium hydroxide 10-25%, Repone K 10-20%, temperature 70-75 ℃, time 3-6 hour.
3. Eucheuma muricatum (Gmel.) Web is taken out and is washed till neutrality, adds glue pot.In dried Eucheuma muricatum (Gmel.) Web, weight accounts for system gross weight 4-10%.Add the Repone K that accounts for system gross weight 3-8% in addition.
