Description

A kind of method that from Eucheuma muricatum (Gmel.) Web, prepares the high-gel strength kappa-carrageenan
Technical field
The present invention relates to a kind of method of from the red algae Eucheuma muricatum (Gmel.) Web, extracting the high-gel strength kappa-carrageenan,, belong to oceanic resources processing and utilization field.
Background technology
Carrageenin (Carrageenan, claim carrageenin, carrageeman again) be a kind of water-soluble colloid that from carrageen (Chondrus), Eucheuma muricatum (Gmel.) Web (Eucheuma), China fir algae (Gigartina) and husky dish multiple red algaes such as (Hypena), extracts, be one of the world's three big seaweed gel Industrial products (agar-agar, carrageenin, algin).Carrageenin is the complex mixture of several polysaccharide, and by 1,3-β-D-galactopyranose and 1,4-α-D-galactopyranose be as basic framework, the linear polysaccharide that alternately is formed by connecting.According to the position difference that half ester formula sulfate is connected, can be divided into seven types, three kinds on the type of type of the type of κ-(Kappa) that mainly contains of industrial production and use at present, ι-(Iota) and λ-(Lamda) on semi-lactosi.κ-type carrageenin can form hard fragility glue, its solidifiability is best, viscosity is lower, be fit to cook jelly, fixed enzyme vector and capsule for medicine etc., industrial most widely used general, especially utilizing the κ of high purity high-gel strength-type carrageenin to manufacture medicinal hard capsule becomes hot research in recent years, so the good kappa-carrageenan of processability, and very significant meaning and use value are arranged.
The Chinese patent literature application number is 03114130.7(publication number CN1450088A) introduced a kind of new process for producing of carrageenin, the carrageenin gel-strength of this invented technology gained is low (less than 1500g/cm 2), and alkali consumption big (concentration of potassium hydroxide is 5~25%) in the alkali modification process, water loss is many during cleaning, and environmental pollution is serious.The Chinese patent literature application number is 200510019044(publication number CN1769302A) method that a kind of diluted alkaline legal system is equipped with the Kappa-carrageenin proposed, though this method has reduced concentration of potassium hydroxide in the alkali modification process (0.5~1%), but employing concentration is 0.05~0.5% mineral acid pre-treatment, easily cause the colloid loss, reduce the colloid yield, and in this patent and the undeclared κ for preparing-type carrageenin gel-strength.The carrageenin product of handling without bleaching is a brown in addition, can not satisfy demand for commodity, does not all mention the problem of carrageenin color and luster and transparency in these two patents.People's bleaching process to carrageenin in the discussion of carrageenin production technique such as beam Qinghua are studied, adopt the sodium hypochlorite bleaching method, but chlorine not only influences operating environment, the infringement workman's is healthy, and bigger to the carrageenan molecule structure deteriorate, cause unstable product quality.
Ion exchange resin is a class novel high polymer parting material that grows up the sixties in 20th century, has the good adsorption performance, and after the nineties in last century, its application is extensive day by day, is particularly demonstrating very strong superiority aspect the separation and purification of natural product.Studies show that in a large number ion exchange resin possesses good physical property, decolouring characteristic and reproducing characteristic are applicable to the decoloration process of polysaccharide very much.
