Root

1 . Evolution of Root Consumption

Ginseng, maca, ashwagandha, turmeric, ginger, chicory, licorice… dried and powdered roots are experiencing remarkable growth, driven by the global enthusiasm for adaptogenic plants, traditional medicine, and natural dietary supplements. Key ingredients in the nutraceutical, cosmetic, and food industries, they are primarily imported from Asia, South America, and Africa, which exposes them to significant microbiological risks throughout their supply chain.

2 . What are the microbiological risks?

Dried roots are products particularly susceptible to microbiological contamination. Harvested from the ground, dried, and packaged in varying environments, roots can harbor pathogenic bacteria (salmonella, E. coli, Listeria), molds, and yeasts, which thrive in excessively high residual moisture or unsuitable storage conditions.

These contaminations can occur at any stage: harvesting, drying, storage, transport, and packaging. A non-compliant batch exposes the operator to costly product recalls, import rejections, and regulatory penalties.

3 . What treatment is used?

Saturated steam pasteurization under vacuum is perfectly suited to dried and powdered roots. This process operates along three dimensions (temperature, time, and pressure) to effectively eliminate pathogens while preserving the active ingredients, organoleptic properties, aromas, and organic certifications of the products.

The parameters are customized according to the root, its specific characteristics, and the microbiological thresholds to be met. Our experts will assist you in determining the protocol best suited to your situation.
