Antioxidant Capture

The system is engineered to selectively adsorb polyphenols, such as quercetin and procyanidins, from the liquid extract. This ensures a high concentration of active compounds in the final product.

Resin Technology

High-affinity macroporous resins are used to trap the target molecules. The process is gentle, preserving the biological activity and chemical structure of the polyphenols.

Value Creation

By recovering polyphenols, apple processors can generate a new revenue stream from peel waste, while also reducing the organic load of their wastewater.

Process concept and operating strategy

The Penta-Poly process involves a multi-stage adsorption and elution cycle, optimized for maximum yield and purity of the polyphenol extract.
