Calcium alginate
- Unique Gel Properties：It can form heat-irreversible gels, which are widely used in bionic food, meat products and other fields to improve product structure and texture
- Efficient Water Retention and Thickening：The gel has excellent water retention capacity and can be used as a food binder, thickener and water retention agent. When used synergistically with sodium alginate, it forms high-calcium gel through calcium-sodium exchange in a saline environment
- Wide Safe and Non-Toxic Applications：Odorless, tasteless and non-toxic, it is insoluble in water and organic solvents but has good dispersibility. It can be safely used in multiple fields such as food and medicine
- Health-Care and Hemostatic Functions：With good water absorption and air permeability, it can be used to make hemostatic gauze, which has hemostatic effects, inhibits bacterial growth and promotes tissue healing.
1. Product Introduction
Calcium alginate is a divalent metal salt of alginic acid, appearing as white to yellowish-white amorphous or fibrous powder. It is odorless, tasteless and non-toxic, insoluble in water and organic solvents, slightly soluble in ethanol, and has good dispersibility. It can be slowly dissolved in alkaline solutions or salt solutions to form viscous colloids.
Molecular Formula: [(C₆H₇O₆)₂Ca]ₙ
2. Product Applications
1> Gelation: Insoluble in water, organic solvents and slightly soluble in ethanol, calcium alginate can form heat-irreversible gels, making it widely applicable in various bionic foods and meat products.
2> Water Retention: Calcium alginate gel has excellent water retention. As a food binder, thickener and water retention agent, it forms thickening high-calcium gel through calcium-sodium exchange under the influence of salt in food, and can be used in combination with sodium alginate.
3> Health-Care: With water absorption and good air permeability, calcium alginate can be used to produce hemostatic gauze, which possesses hemostatic functions, prevents bacterial infection and accelerates tissue healing.
