Sodium Alginate Bulk

Sodium Alginate Bulk: Premium Natural Polysaccharide for Industrial Applications

Avans NutriHealth Co., Ltd. supplies pharmaceutical grade Sodium Alginate Bulk, produced from premium brown seaweed using cutting-edge biotechnology technologies. This natural polysaccharide is manufactured by Avans (Qingdao) NutriHealth Technology Co., Ltd. Viscosity is from 150 to 600 mPa·s (1% solution, 20°C). Ash level is managed at 18%-27%. Particle sizes are available in 80-200 mesh standards. We are backed by certifications like as BRC, ISO, FDA, Kosher, Halal, HACCP and FSSC22000. We are consistent batch to batch with heavy metal levels well below international norms (Lead <2ppm, Arsenic <3ppm). This white powder substance provides consistent gelling, thickening and stabilising performance in challenging production conditions.

Technical Specifications & Properties

You can optimise your formulations knowing the physical and chemical properties of this seaweed-derived polysaccharide. Our product performs very well under different processing circumstances.

The material consists of a linear copolymer of β-D-mannuronic acid (M) units and α-L-guluronic acid (G) units. The M/G ratio influences the gel properties, where a high G-content produces stiff and brittle gels, suitable for restructured meals, while a high M-content produces flexible and elastic textures, suitable for biomedical applications.

It is easily added to operations that operate at room temperature as it dissolves in cold water. The pH range of 6.0–8.5 (1% solution) is compatible with most neutral formulations, however acidic conditions below pH 4.0 will require special formulations.

Key Parameters

Industrial Applications & Solutions

Sodium Alginate Bulk solves critical manufacturing challenges across three primary sectors where consistency and performance are non-negotiable.

Food & Beverage Manufacturing: Gain accurate control in meat restructure, dairy stabilisation, and molecular gastronomy. The binding is heat stable and holds the texture in place during thermal processing. Spherification applications provide a new culinary experience with consistent outcomes.

Textile Printing & Dyeing: It is used as a principal thickener for reactive dyes, providing great colour yield and precise pattern definition. The substance does not interact with dye molecules, so it washes off easily and keeps the fabric supple. Consistent viscosity management helps enhance your efficiency of manufacturing.

Pharmaceutical & Biotech: Micro-encapsulation of sensitive active ingredients provides the benefits of controlled release mechanism. Biocompatible wound dressing matrices retain their structural integrity upon exposure to physiological fluids. High-shear processing has little impact on material performance.

Storage & Handling Guidelines

Proper storage protects your investment and keeps product performance intact for the full 24 month shelf life. Store containers in cool, dry warehouses, away from direct sunlight and moisture.

Do not open the original packaging until usage to avoid moisture absorption. Optimal temperatures are between 15-25°C. Avoid cross-contamination by handling material with dedicated equipment.

For dissolution, employ high shear mixers or pre-blending with dry ingredients (e.g., sugar or starch). This method prevents the creation of "fish-eyes", and assures a uniform dispersion. In hard water, add sequestrants such as sodium hexametaphosphate before adding the powder.

Quality Assurance & Testing Protocols

Incoming material quality is critical to your production reliability. There are five-stage testing processes, eliminating expensive batch failures and equipment downtime.

Standardised concentrations were used for viscosity measurements using Brookfield Viscometer. This guarantees rheological consistency which is important for automated filling lines and coating applications. Total ash analysis for purity certification. Mineral balance without extra salts that interfere with your formulations.

ICP-MS testing for heavy metal profiling provides adherence to safety regulations in worldwide markets. Gel Strength Determination Measures calcium-set gel penetration force, validating structural reliability in finished products. Microbiological screening is conducted for Total Plate Count, E. coli and Salmonella that comply with pharmaceutical and food-grade requirements.

Each batch is supplied with full Certificate of Analysis, recording all test results. This documentation is intended to support your quality audits and regulatory submissions.

FAQ

Q: Why does the powder clump when it is dissolving?

A: Fast surface hydration leads to agglomeration. To obtain a uniform distribution in the liquid phase, high shear mixers or pre-blending using dry carriers should be used.

Q: I would like to use this material in acidic formulations as low as pH 4.0.

A: At low pH pure sodium alginate may precipitate as alginic acid. If an acid application is required, check out the Propylene Glycol Alginate (PGA) options we have available.

Q: How do I adjust the rate of gelling with calcium?

A: Sequestrants such sodium citrate or tetrasodium pyrophosphate. These compounds slow the cross-linking reactions and prolong your working time.

Q: Is the final viscosity dependent on particle size?

A: Final viscosity is a function of molecular weight and not particle size. However, the granular types have lower dissolution rate than the finer mesh sizes (200 mesh) which significantly improves the processing efficiency.

Q: How long will it last?

A: The product has a 24 month stability with no loss of viscosity when stored in cool, dry conditions in the original sealed container.
