Sodium alginate is a by-product of iodine and mannitol extracted from brown algae kelp or Sargassum. It is a natural polysaccharide with the stability, solubility, viscosity and safety required for drug excipients. Sodium alginate has been widely used in the food industry and other fields.
The process flow of sodiumalginate: dry or wet seaweed (algae) is crushed, washed to remove impurities, extracted with strong alkaline water, and clarified to obtain a crude alginate solution, and precipitated with calcium chloride to obtain colored calcium alginate. After decolorization and deodoriza
tion, it is treated with acid to remove soluble impurities to obtain alginic acid precipitation, which reacts with sodium carbonate to obtain sodium alginate, which is then dried, crushed and sieved to obtain sodium alginate powder.
1. Application in food
Food grade sodium alginate: Sodium alginate is used as a stabilizer for ice cream instead of starch and gelatin. It can control the formation of ice crystals and improve the taste of ice cream. It can also stabilize mixed beverages such as syrup, sherbet, and frozen milk.
Sodium alginate is used as a thickener for salad (a kind of cold dish) sauce, pudding (a kind of dessert), jam, tomato sauce and canned products to improve the stability of the product and reduce liquid exudation.
Adding sodium alginate in the production of dried noodles, vermicelli, and rice noodles can improve the adhesion of the product structure, make it strong, curved, and reduce the rate of broken ends, especially for the low gluten content of flour, the effect is more obvious. Adding sodium alginate to bread, cakes and other products can improve the uniformity and water retention of the internal tissue of the product, and extend the storage time. Adding to frozen dessert products can provide a thermal fusion protective layer, improve fragrance escape, and improve the performance of melting point.
2. Application of printing and textile industry
Sodium alginate is used as a reactive dye paste in the printing and dyeing industry, which is superior to grain starch and other pastes. The printed textile has bright patterns, clear lines, high color yield, uniform color, and good permeability and plasticity. Seaweed gum is the best slurry for modern printing and dyeing industry. It has been widely used in the printing of cotton, wool, silk, nylon and other fabrics. It is especially suitable for the preparation of discharge printing slurry.
In food industry, as gelatinizing agent, thickener, deflocculant used in health food such as ice cream, beverage, form food, meat product, jam ,health, etc.
In drug industry, used as bonding agent, biology bonding agent, sustained-release and controlled-release tablet, dressing, dental impression material .firming agent etc.
In daily industry: used as peel mask, thickening stabilizing agent for cosmetic.
In fodder industry: Used as fodder bonding agent , pet food bonding agent, etc.
