Sodium alginate is a by-product after iodine and mannitol are extracted from kelp or sargassum of brown algae, and its molecule consists of β-D-mannuronic (β-D-mannuronic, M) and α-L-guluronic (α-L-guluronic, G) connected by (1→4) bond, which is a kind of natural polysaccharides, with the stability, solubility, adhesion, and safety of excipients required for the pharmaceutical preparations. and safety.

Advantages:
Sodium alginate, as a thickener for beverage and dairy products, has unique advantages in thickening: the good fluidity of sodium alginate makes the added beverage taste smooth; and it can prevent the phenomenon of decreasing viscosity in the process of sterilisation of products. When using sodium alginate as a thickener, we should try to use products with larger molecular weight, and add Ca in the right amount, which can greatly improve the viscosity of sodium alginate.
Sodium alginate is used as a stabilizer for dairy products and beverages, and the stabilised frozen buttermilk has a good taste without stickiness and stiffness, and it is viscous and has a sluggish feeling when it is stirred.
Applications:
1.Food industry
Thickener: sodium alginate is commonly used as a thickener and gelling agent in food, such as in jams, jellies, ice creams and condiments.
Stabiliser: used in dairy products and beverages to help stabilise the texture and consistency of the product.
Encapsulation material: In molecular cuisine, used to encapsulate liquids to make spherical or capsule-shaped food products.
2.Pharmaceutical field
Sodium alginate is used as a carrier and stabiliser for drugs to help them work better. In addition, it can also be used as a biological material for the manufacture of artificial bones, teeth and other medical devices, showing good biocompatibility and degradability.
3.Industrial Applications
Water treatment: Sodium alginate is used to remove heavy metal ions and pollutants from water during water treatment.
Textile industry: Sodium alginate is used as reactive dye colour paste in printing and dyeing industry, which is superior to grain starch and other pastes. The printed textiles have bright patterns, clear lines, high colour supply, uniform colour, good permeability and plasticity. Seaweed gum is the best paste for modern printing and dyeing industry, now widely used in cotton, wool, silk, nylon and other fabrics printing, especially suitable for the preparation of dial dyeing printing paste.
4. In the field of agriculture, sodium alginate is used as soil conditioner and plant growth regulator to promote crop growth and improve yield.
5. Environmental protection field, sodium alginate is a kind of biodegradable environmental protection material, can be used in the manufacture of bioplastics, paper, etc., to reduce the pollution of the environment.
