Plant and Clay

1 . Evolution of plant and clay consumption

Plants, plant powders, and clays are experiencing significant growth in the food, cosmetics, nutraceutical, dietary supplement, and natural formulation markets.

The rise of clean label products, organic products, and natural ingredients is increasing the demands for quality and microbiological safety.

These sensitive raw materials now require treatment solutions capable of guaranteeing their compliance while preserving their functional and organoleptic properties.

2 . What are the microbiological risks?

Plants and clays are naturally exposed to microbiological contamination during cultivation, harvesting, drying, grinding, transport, and storage.

These matrices can contain:

  • pathogenic and non-pathogenic bacteria,
  • yeasts,
  • molds,
  • spores,
  • environmental contaminants.

Products with low moisture content remain particularly susceptible because some microorganisms can survive for extended periods in these dry environments.

3 . What treatment is used?

Saturated steam pasteurization under vacuum is the standard treatment for plants and clays. This process operates along three dimensions (temperature, time, and pressure) to effectively eliminate pathogenic and non-pathogenic bacteria while preserving organoleptic qualities, aromas, color, product-specific properties, and organic certifications.

The parameters are customized according to the nature of the product, its initial moisture content, and the microbiological thresholds to be met. Our experts will assist you in determining the protocol best suited to your situation.
