Penta-Dei systems are high-performance plants designed for the complete deionization of apple and pear juice. By removing minerals, organic acids, and coloring matter, these systems produce a clear, stable, and neutral sugar base (deionized juice) that is ideal for use as a natural sweetener in the food and beverage industry.

Mineral Removal
The system effectively removes all cations and anions from the juice, resulting in a solution with extremely low conductivity and high chemical purity.
Color Stability
By removing polyphenols and other color precursors, the deionization process ensures that the final juice base remains clear and does not brown over time.
Neutral Base
The deionized juice is a neutral sugar solution that can be used as a “clean label” sweetener, providing sweetness without affecting the flavor profile of the final product.
Process concept and operating strategy
The Penta-Dei process utilizes a sequence of cationic, anionic, and decolorizing resins to achieve the highest level of juice purification.

FAQ
The Brix remains largely unchanged, as the system removes minerals and acids but preserves the natural sugars (glucose, fructose, and sucrose).

With proper maintenance and regeneration, the resins can last for several years of continuous operation.
