Immune Function sodium alginate

Immune Function of Algal Polysaccharides in Laminaria Japonica

Algal polysaccharides (sodium alginate) can act as biological adsorbents, nutrient resources of other marine organism and coldness-protective agents of cellular materials. It helps to reduce blood lipid, exert antioxidant function and to enhance immune regulatory activity and prepare microcapsule. Algal polysaccharides are likely to become the main drug resources for human beings.

 

According to the composition, algal polysaccharides can be classified into 3 types: high G/M ratio, medium G/M ratio and low G/M ratio. Based on viscosity, they can be classified into sodium alginate of low viscosity, medium viscosity and high viscosity.

 

Algal polysaccharide (sodium alginate) is a kind of substance with natural activity and it plays an important role in regulating the immune function of the body by promoting proliferation and differentiation of lymphocytes, stimulating macrophage phagocytosis and boosting the production of cytokine and antibodies.

 

Prospect analysis of algal polysaccharides

 

Algae (sodium alginate) can not only be directly eaten as marine vegetables but also be used in extracting various kinds of functional ingredients. At present, the most widely used functional food ingredients all over the world that take advantage of algae extraction are natural algal polysaccharide products like sodium alginate extracted from brown algae like laminaria japonica and giant kelp.

 

Alginates are first discovered and extracted from algae plants by British chemist E.C.C.Stanford and nearly 50 years later, in 1929, American Kelco Company began the mass production of sodium alginate as a commodity and it became the only natural anion salt polysaccharide with mature application and industrialization.

 

Afterwards, the sodium alginate industry led by alginates continued to develop and grow. Especially since the 1980s, due to the distinctive properties such as gelling, thickening and emulsifying functions and biological activity, the application of sodium alginate in the food industry has been developed and it has gradually become a fine product to raise people’s living and health standards. Alginates mainly include sodium alginate, potassium alginate, calcium alginate and ammonium alginate, of which sodium alginate has become the functional food ingredient with the maximum production and sales extracted from algae.
