Sodium alginate has stability, heritability, and gelation properties, so it's widely used to place starch, and gelatin as the stabilizer of ice cream, beverages, and many dairy products. If it's added to salad dressing, pudding, jam, tomato paste, and canned foods, it tends to improve the stability of products and reduce fluid. We can add sodium alginate in the dry noodles, vermin exudation celli, rice vermicelli, and bread which can improve the product's group cohesiveness, make the tension strong, and reduce the breakage. The effect is more apparent for flour with low gluten content and the storage time will be extended.
In printing and textile industry sodium alginate has been a long history since sodium alginate was used in starching , packing and printing. In printing, it is the good material with wide use in the cotton, wool, silk and synthetic fibre. Especially since the reactive dye was found in the world, there has been many years' history of application. There is no other gelatinigation which can compare beauty with it by so far. Sodium alginate can't react with the reactive dye or form covalent bond as result of having second hydroxyl in its structure without the origin hydroxyl, and meanwhile having strong cathodic carboxyl in its organization. This is its great property. Therefore, it not only does not absorb the dyestuff but also excludes it. It is easy to move the dyestuff from the gelatinigation to the firbre which benefits keeping clearness and uniformity of the printing. Therefore the printing is clear, vivid, high in the dyeing quantity and has good handle and firm degree at the same time. The products of medium and low viscosity are suitable for the printing requirements of net, roll style and handwork printing. It has the flowing property of the pseudoplastic fluid, which means that it will turn watery when being cut and restore the original viscidity after losing being cut. This fits for fine printing, full ground printing and wet printing. It can make products with the features of thin line, clear profile and good uniformity.
