Preservative Function & pH Performance
Microbial Inhibition: Directly targets and suppresses the cellular reproduction of molds, yeasts, Staphylococcus aureus, and Salmonella.
Preservation Mechanism: Functions primarily through growth inhibition rather than direct sterilization, preserving food matrix stability without destroying beneficial flora like Lactobacillus acidophilus.
Flavor Integrity: Neutral taste profile prevents alterations to product sensory attributes, making it suitable for sensitive feed and food matrices.
Application Conditions
Food Processing Concentration: Permitted usage rates range between 0.02% to 0.1% across noodle items, pickles, canned goods, dried fruits, dairy, and condiments.
Animal Feed Utilization: Incorporated at controlled ratios to prevent feed mold growth and significantly suppress aflatoxin creation without altering palatability.
Industrial & Material Integration: Applied at 0.1% concentration in rubber production, alongside variable dosing for paper and plastic packaging depending on factory specifications.
Quality Control & Documentation
Batch COA: Each batch can be accompanied by a Certificate of Analysis showing the tested values against the agreed specification.
Incoming Material Verification: Key quality parameters are checked against defined requirements before the product enters production or packing.
Specification Traceability: Batch information and test records provide a reference for buyers' incoming inspection and internal quality documentation.
Supporting Documents: Product specification, COA, SDS and other applicable documents can be provided according to order and destination requirements.
