What Preservation Methods Do You Use for Alcohol-Free Liquid Supplements?

FORNUTRA offers comprehensive OEM and ODM services for liquid supplement manufacturing, backed by our GMP-certified facility and experienced technical team. We prioritize quality, transparency, and flexibility throughout every engagement.

For alcohol-free liquid supplements, FORNUTRA employs a combination of preservation strategies selected based on your product formulation and target market regulations. Common methods include thermal pasteurization or UHT treatment to eliminate microorganisms, pH adjustment to create an environment hostile to bacterial growth, and the use of GRAS-approved preservatives such as potassium sorbate, sodium benzoate, or natural alternatives like rosemary extract and citric acid.

Where aseptic processing is preferred for heat-sensitive ingredients, we use sterile filling technology in a controlled environment to prevent post-processing contamination. Water activity management and nitrogen headspace flushing further extend shelf life by reducing oxidation. Every formulation undergoes microbial challenge testing and accelerated stability studies to validate the chosen preservation system.
