Preservative Function & Formulation Considerations
Yeast & Mold Control
Sorbic Acid is primarily used to control yeast and mold growth in permitted food formulations.
PH Consideration
Its preservative activity is influenced by the pH of the finished food. The permitted use level should be established according to the specific food category and target market.
Solubility & Incorporation
Sorbic Acid is slightly soluble in water and soluble in ethanol. Liquid formulations may require an appropriate dissolution or dispersion step before incorporation.
Application & Formulation Matching
Bakery Products
Bread, cakes, pastries and related bakery products where mold control is required during storage.
Fruit Preparations
Fruit pulp, purees, toppings and processed fruit products where sorbate preservation is permitted.
Sauces & Vegetable Preparations
Sauces, vegetable purees, spreads and other prepared foods covered by applicable sorbate provisions.
Confectionery
Selected confectionery products where preservation against yeast and mold is required during storage.
Beverage Systems
Specific beverage and alcoholic beverage categories where sorbates are permitted under applicable food-additive regulations.
Quality Control & Batch Documentation
Batch Release Checks
Each production batch is checked against the agreed product specification before release, including identity, assay and applicable physical and impurity parameters.
Physical & Chemical Verification
Finished-product testing covers the relevant appearance, water, melting range, residue on ignition and aldehyde requirements specified for the product.
Heavy Metal Control
Lead, arsenic, mercury and total heavy metals are checked against the specified limits for the supplied grade.
Batch COA
A batch-specific Certificate of Analysis records the applicable test results for comparison with the agreed specification during incoming inspection.
Supply & Packaging Options
Export Packaging
Sorbic Acid is supplied in packaging suitable for food-ingredient storage and international transportation. Package size and format can be confirmed according to order requirements.
Package Identification
Commercial packages can carry the product name, net weight, batch information and required shipping or traceability details.
