Sodium Alginate Food Grade

Powder Dispersion

Add sodium alginate gradually into the liquid phase under continuous agitation to promote even dispersion and reduce lump formation during preparation.

Hydration

Allow sufficient hydration before viscosity measurement or subsequent formulation processing. Hydration time and mixing conditions should remain consistent when comparing batches or suppliers.

Viscosity Testing

Control solution concentration, water temperature, mixing procedure and hydration time when measuring the 1% solution viscosity specified for this grade.

Production Transfer

Keep the addition sequence, mixing conditions and hydration procedure consistent between laboratory trials and production wherever the process allows, helping maintain comparable processing behavior.

Viscosity Control

Sodium alginate develops viscosity after hydration and can be used to adjust the body and flow characteristics of aqueous food formulations. The resulting viscosity varies with concentration, grade and processing conditions.

Calcium-Induced Gel Formation

In the presence of calcium ions, alginate forms calcium alginate gel structures. This property is relevant to food formulations requiring a defined gel shape or set texture.

Sauces, Dressings & Fruit Preparations

Suitable for formulations where viscosity adjustment, ingredient suspension or a controlled texture is required.

Dairy & Frozen Foods

Applicable to dairy-based and frozen formulations where sodium alginate is selected for stabilization and texture adjustment.

Beverage Formulations

Suitable for formulated beverages containing dispersed ingredients where viscosity and suspension properties need to be controlled.

Bakery & Processed Foods

Can be incorporated into bakery fillings and processed food formulations requiring alginate-based thickening or structure control.

Restructured & Bionic Foods

Relevant to products formed through calcium-induced alginate gelation, where a defined shape or gel structure is required.

Physical & Chemical Checks

Finished batches are checked for appearance, assay, viscosity, loss on drying, pH and ash against the established product specification.

Heavy Metal Testing

Lead, arsenic and total heavy metals are controlled against the specified limits for the finished product.

Microbiological Testing

Microbiological control covers total plate count and yeasts & moulds, with specified requirements for pathogenic germs, S. aureus, Pseudomonas aeruginosa, Salmonella and C. perfringens.

Batch Documentation

Test results are recorded against the applicable batch specification and can be supplied through the commercial COA for incoming inspection and supplier qualification.

Technical Documents

TDS, SDS and batch COA can be provided for product evaluation, supplier qualification and incoming inspection.

Food Additive Identification

The product is identified as sodium alginate, INS 401 / E401. Food additive requirements can be reviewed according to the destination market and intended food application.

Batch Quality Records

COA results cover the agreed product specification and applicable quality parameters for each commercial batch.

Export Documents

Commercial and shipping documents can be prepared according to the order and destination requirements for customs clearance and importer records.

Standard Packaging

25 kg bags, drums or cartons are available as standard packaging options.

Packing & Labeling

Pack size, outer packaging and product labeling can be discussed according to the order requirements and available packing arrangements.

Storage

Store in a cool, dry place and keep the packaging sealed during storage and handling to reduce moisture exposure.

Bulk Shipment

Bulk order packing and shipping arrangements can be confirmed according to order quantity and destination.
