 Applications 

1. Bakery & Tortilla — sliced bread, buns, tortillas, cakes and part-baked goods: Inhibits mould and the rope-forming Bacillus species that spoil bread, extending mould-free shelf life without touching the crumb. It is selective against mould and bacteria while leaving baker's yeast active, so fermentation and proof are unaffected at normal inclusion levels.

2. Cheese, Dairy & Processed Cheese — processed cheese, cheese analogues, surface treatment of natural cheese: Controls surface mould and smear on cheese and prevents the mould growth that limits shelf life in packaged processed cheese. Highly soluble and neutral in taste at effective levels, so it does not disturb the flavour profile of a mild dairy base.

3. Compound Feed & Pet Food — poultry, swine and ruminant feed, extruded pet food, premixes: A mould inhibitor that protects feed through humid storage and prevents the heating, caking and mycotoxin risk that follow fungal growth. Also supports gut health as a short-chain fatty acid source, which is why it appears in antibiotic-free feeding programmes.

4. Silage, Haylage & Grain Storage — maize and grass silage, high-moisture grain, hay preservation: Suppresses mould and yeast at the silage face and in high-moisture grain, reducing dry-matter loss, heating and aerobic spoilage after opening. Helps hold feed value through storage instead of losing it to fungal respiration.

5. Sauces, Dressings & Acidified Foods — ketchup, dressings, pickled products, acidified vegetable preparations: Works as a preservative in the pH range where propionate is active, controlling mould and yeast in high-moisture acidified systems. Pairs well with sorbate and benzoate to cover a broader spoilage spectrum.

6. Technical & Industrial Preservation — adhesives, starch and protein-based binders, technical emulsions: Protects water-based technical products from mould and bacterial spoilage during storage, particularly starch and protein systems that are prone to fungal growth.

 Quality Assurance 

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
