Sodium Alginate is the white crystal whose appearance and smell are similar to sugar. In the food industry, Sodium Alginate has the functions of stabilization, hydration, thickening and emulsification. In the pharmaceutical industry, it can be used as dental impression material, ointment, tablets and their preparation, and hemostat. In agriculture, Sodium Alginate can be used as seed treatment, insecticides and anti-viral materials. It also can be used in resin coating, rubber cream agent, water treatment and so on. As a leading food additives and food ingredients supplier in China, we can provide you with high quality Sodium Alginate.

Alginate absorbs water quickly, which makes it useful as an additive in dehydrated products such as slimming aids, and in the manufacture of paper and textiles. It is also used for waterproofing and fireproofing fabrics, as a gelling agent, and for thickening drinks, ice cream and cosmetics.

Alginate is used in various pharmaceutical preparations such as Gaviscon, Bisodol, and Asilone. Alginate is used extensively as an impression-making material in dentistry, prosthetics, lifecasting and occasionally for creating positives for small-scale casting. It is also used in the food industry, for thickening soups and jellies.

Calcium alginate is used in different types of medical products, including burn dressings that promote healing and can be removed with less pain than conventional dressings.

Also, due to alginate's biocompatibility and simple gelation with divalent cations such as Ca2+, it is widely used for cell immobilization and encapsulation.

Alginic acid (alginato) is also used in culinary arts, most notably in the Sphereification techniques of Ferran Adrià.

Due to its ability to absorb water quickly, alginate can be changed through a lyophilization process to a new structure that has the ability to expand. It is used in the weight loss industry as an appetite suppressant.

In March, 2010 researchers at Newcastle University announced that dietary alginates can reduce human fat uptake by more than 75%.
