Potassium Sorbate Preservative

PH Range

Potassium Sorbate is used mainly in acidic formulations. Check the finished-product pH before setting the preservative system and addition level.

Water Phase

The ingredient is freely soluble in water and can be dissolved in the water phase before mixing with the finished formulation.

Target Microorganisms

Its preservation function is directed mainly at yeasts and moulds. Formulations requiring control of bacteria should be assessed separately rather than relying on Potassium Sorbate alone.

Use Level

Addition levels are determined by the food category, finished-product formulation and applicable local regulation. Confirm the permitted level before production-scale use.

Bakery Products

Bread, cakes, pastries and related bakery products requiring mould control.

Beverages & Fruit Products

Selected fruit beverages, syrups and fruit preparations where sorbate use is permitted.

Dairy & Cheese Products

Selected cheese and dairy products requiring yeast or mould control.

Sauces, Dressings & Pickled Foods

Sauces, dressings, pickled foods and seasoned products within applicable additive categories.

Noodles, Canned Foods & Dried Fruits

Noodle products, canned foods and dried fruits listed among the application categories for Potassium Sorbate.

Crystalline Powder

Fine crystalline material for direct weighing, dry blending or preparation before batch addition.

Granular Form

Granular material for production lines using mechanical or metered feeding.

Particle Size

Particle size can be specified according to feeding, premixing or dissolution requirements.

Temperature

Store in a cool, dry and well-ventilated area at temperatures of ≤38°C.

Light & Fire

Keep away from direct light and fire sources during warehouse storage and handling.

Chemical Segregation

Do not store together with poisons or incompatible hazardous materials.

The storage conditions are kept separate from the physical-form section so that warehouse requirements are not mixed with powder/granule handling characteristics.

Raw Material Inspection

Incoming materials are checked for appearance, identification and moisture before production. Materials outside the approved specification are not released for processing.

In-Process Sampling

Intermediate samples are checked for appearance, moisture and batch uniformity during production. Samples are retained for comparison with the finished-product test results.

Finished Product Analysis

The finished batch is tested for identification, assay, loss on drying, acidity/alkalinity and applicable impurity limits. Heavy metals, lead and arsenic are tested where included in the agreed specification.

Batch Release

A representative finished-product sample is submitted for laboratory analysis. The batch is released after test results meet the approved specification, with the results recorded on the batch COA.

Standard Bulk Packing

Potassium Sorbate is supplied in food-grade bulk packaging with an inner liner to protect the powder or granules during storage and transport.

Palletized Orders

Pallet packing can be arranged for larger-volume shipments to simplify warehouse receiving, container loading and cargo handling.

Package Marking

Outer packaging can carry the product name, net weight, batch/lot number and shipping marks. Customer-specified labels or package information can be applied when required.
