Versatile for multiple scenarios, adaptable to the production needs of all industries. Nourisi® Sodium alginate has a wide range of uses and is a veritable "universal industrial raw material," covering all mainstream application scenarios:

● Food Industry: Widely used in ice cream, yogurt, juice, sauces, meat products, pasta. In frozen drinks, it refines ice crystals and prevents melting and separation; in sauces and beverages, it stabilizes the system and prevents sedimentation and separation; in meat products and pasta, it locks in moisture and elasticity, resulting in a firm and chewy texture, significantly improving product taste and shelf-life stability.

● Textile Printing and Dyeing Industry: As a special thickener for printing, it has a fine consistency, good penetration, prevents color bleeding, produces rich colors, and leaves no residue after washing. It is suitable for printing on various fabrics such as pure cotton and synthetic fibers, making it a high-cost-performance essential raw material for the printing and dyeing industry.

● Daily Chemical and Beauty Industry: Used in face masks, lotions, toothpaste, and personal care products, it acts as a thickener, stabilizes the texture, and smooths the consistency. It is gentle on the skin and suitable for various mild personal care formulas.
