Penta-Met systems are high-precision plants designed for the selective removal of heavy metals (such as iron, copper, lead, and arsenic) from food-grade solutions, including fruit juices, syrups, and liquid sweeteners. By utilizing advanced chelating resins, these systems ensure that the final product meets the strictest international safety standards for metal content without altering the solution’s organoleptic properties.

Food Safety
The primary goal of the Penta-Met system is to guarantee the safety of food solutions by reducing heavy metal concentrations to trace levels, ensuring compliance with global health regulations.
Selective Removal
The system uses specialized chelating resins that have a high affinity for specific metal ions, allowing for targeted removal while leaving essential minerals and nutrients intact.
Quality Preservation
The process is designed to be gentle on the food solution, preserving its color, flavor, and nutritional value, making it ideal for high-quality juice and syrup production.
Process concept and operating strategy
The Penta-Met process utilizes a sophisticated ion-exchange mechanism where metal ions are captured by functional groups on the resin surface.
