Sodium alginate

Alginate is a kind of natural polysaccharide consisted in brown seaweed,as a natural product generated from alginic acid indwell in seaweed and minerals indwell in sea. Alginic acid is a mix-polysaccharide composed of D-mannuronic acid (M) L-guluronic acid (G).The main alginate series include sodium alginate, potassium alginate, calcium alginate,ammonium alginate etc.

Chemical structure:
Solution properties:

As thehydrophilic gel,sodium alginate is the prevailing salt of algin,which is apt to form thick solutions (RE.the picture).With the properties of thickness and stability,sodium alginate can be used as thickener and stabilizer in foodstuff,and printing paste,oil-extraction agent etc.

Gelling characteristic:

When meeting with calcium,ion exchange notion takes place rapidly to form gel, and the gel is anti-reversibility.The high G alginate gel is crispness but much rigider,while the high M alginate gel has the opposite property,flexibler with less rigidity.Different strengths of gel made by different proportions工RE.the picture).With different gel,alginate can be used for difference of imitated food,medical materials,face masks,water treatment agents,clingfilm etcs.

Health care functions:

1、Alginate is a kind of macromolecule amylose that edible but unable digestant for human body, which has functions of hygroscopicity,adsorption,cation exchange, gelling and filtration in stomach and tharm:

·Reduce blood pressure,blood fat,cholesterin,and defend fatty liver;

·Prevent and remove radioactive element and poisonous metals;

·Increase the paunch saturation to lose weight healthily;

·Increase the peristalsis of the intestines and stomach to prevent conshpahon.

2、The low molecularized alginate has much stronger biological activity with obvious health care functions.

·The low molecularized potassium alginate can adjust and defend hypertension, postpone cardiovascular caducity,improve microcirculation;

·The low molecularized sodium alginate can reduce the blood fat;

·The low molecularized calcium alginate is a new source to supplement calcium, and be easy to absorb;

·The low molecularized zinc alginate is good for brain and to defend agedness dementia;

·The low molecularized iron alginate can supplement iron and blood;

·The low molecularized magnesium alginate can prevent and cure coronary heart disease;

Also,alginate can be used for healthy function food and Pharmaceutical Materials.
