 Sodium alginate, also known as sodium alginate, kelp glue, alginate, alginate, a natural polysaccharide carbohydrate extracted from seaweed. Sodium alginate is widely used in food, medicine, textile, printing and dyeing, paper making, daily chemical products, use as thickeners, emulsifiers, stabilizers, binders, sizing agents. Since the 1980s, sodium alginate in food applications have been further expanded. Sodium alginate is not only a safe food additive, and can be used as the substrate of the bionic food or efficacy food, because it is actually a natural fiber, can slow the absorption of fat, sugar and bile salts, and with lower serum cholesterol, the role of triglycerides and blood sugar in the blood, can prevent hypertension, diabetes, obesity and other modern diseases. Can inhibit the sodium alginate in the gut of harmful metals such as strontium, cadmium, lead accumulation in the body, precisely because such an important role in sodium alginate, both at home and abroad have increasingly been paying attention. The Japanese are rich in sodium alginate food known as the "longevity food", the Americans called it "wonderful food additive".
