Sodium alginate, also known as brown alginate, is a natural polysaccharide extracted from brown algae (such as kelp and sargassum). It is formed by the linkage of β-D-mannuronic acid and α-L-guluronic acid through glycosidic bonds. Its aqueous solution has a high viscosity and can rapidly form gels upon the presence of divalent metal ions such as calcium, copper, and zinc (the "egg box" model). Sodium alginate possesses excellent properties such as non-toxicity, water solubility, good biocompatibility, biodegradability, and pH sensitivity. It also has functions such as thickening, stabilizing, emulsifying, film-forming, gelling, flocculating, and chelating. It is widely used in various fields such as food, medicine, cosmetics, and textile printing and dyeing.
Sodium Alginate - Application Characteristics
I. Food Industry
Thickening and stabilizing agents: As stabilizers for frozen beverages such as ice cream and ice lollies, they can control the growth of ice crystals, improve the taste, and prevent the products from deforming due to temperature fluctuations during storage and transportation.
Gelation and texture improvement: It is used to form gels in products such as jam, pudding, and jelly to maintain the stability of their shape; in low-fat meat products and dairy products, it can replace some fat and improve the taste and texture of low-fat foods.
Cereals and baking: Added to noodles and vermicelli to enhance adhesion and tensile strength, and reduce breakage; used in bread and pastries to improve internal structure uniformity and water retention, and extend shelf life.
Other uses: It can be used as a thickening agent for syrups and processed fruits, a stabilizer for salad dressings, and a protective layer covering the surface of fruits and meat products for preservation.
II. Medicine and Medical Devices
Drug formulation excipients: Sodium alginate can be used as a binder, suspending agent, emulsifier, microcapsule matrix, etc. for tablets; its pH sensitivity can be utilized to achieve sustained and controlled release of acidic drugs.
Wound dressing: A medical wound dressing made of sodium alginate, which can provide an appropriate moist environment for superficial wounds and has biocompatibility as well as certain antibacterial properties.
Tissue engineering and hemostasis: It can be made into hydrogels to serve as tissue engineering scaffolds, used for tissue repair such as cartilage, bone, and skin; it can also be made into hemostatic sponges and hemostatic gauze as hemostatic materials.
III. Cosmetics and Personal Care Products
Moisturizing and Film Formation: A combination of sodium alginate and hyaluronic acid (also known as hyaluronic acid) can provide dual moisturizing effects and form a protective film on the skin surface, thereby improving skin texture.
Active ingredient protection and delivery: After chemical modification (such as acetylation), sodium alginate can be used as a nano-carrier to encapsulate bioactive substances such as antioxidant peptides and polypeptides, enhancing their stability and transdermal ability, and being applied in functional skin care products for anti-aging and whitening purposes.
IV. Industry and Other Fields
Dyeing and Textile Processing: Sodium alginate is one of the best sizing agents for reactive dye printing, resulting in bright colors and clear lines. It can also be used as a sizing agent for warp yarns, reducing the breakage rate.
Agriculture and Water Treatment: Sodium alginate has certain flocculation and chelating properties and can be used in water treatment; there are also studies on promoting plant growth and other aspects in agriculture.
