Use Function of Sodium Alginate:

For edible use, sodium alginate is chiefly used as the raw material of making bionic foods,jellies and proplene glycol alginate sodium, and it also can be used as a kind of thickening agent, stbilizer or emolsififier in the processing of beverages, cakes, can dies and foodstuffs, which is an ideal additive helpful to improve your health.

For medicinal use, sodium alginate is the raw material of producing pss,and X-RAY developer carrier and so on.

For industrial use, sodium alginate is chiefly used as a kind of reactive dyes in printing-and dyeing industry, And besides, it can be used to apply glue in the making of paper and to thicken cosmetics or detergents.
