Debittering
Pomegranate juice can contain high levels of bitter tannins and polyphenols. Our selective adsorption resins target these specific molecules, smoothing the juice’s astringency while maintaining its characteristic deep red hue and nutritional value.
Deacidification
To achieve the perfect balance between sweetness and tartness, our ion-exchange process reduces excess organic acids. This allows for precise adjustment of the Brix/Acid ratio, making the juice more appealing to a wider range of consumers.
Preservation
Our gentle treatment process is designed to protect the delicate anthocyanins and antioxidants that make pomegranate juice a “superfood.” The result is a refined juice that is both delicious and highly functional.
Process concept and operating strategy
Pomegranate juice processing requires specialized knowledge to handle its unique chemical composition. PentaSTAB systems provide a reliable solution for industrial-scale refinement.
The juice flows through columns containing specialized adsorption resins. These resins are calibrated to capture the specific tannins and polyphenols responsible for excessive bitterness and astringency, without stripping away the juice’s natural character.
By utilizing weak base anion exchange resins, we can selectively remove citric and malic acids. This process is fully adjustable, allowing producers to standardize their juice to specific quality targets regardless of the raw material’s initial acidity.
Our resins and process parameters are optimized to ensure that the juice’s natural pigments (anthocyanins) are not adversely affected, resulting in a final product with excellent color stability and visual appeal.
- Effective removal of bitter tannins and astringent compounds.
- Precise Brix/Acid ratio adjustment for flavor balance.
- High retention of antioxidants and natural pigments.
- Fully automated operation with PLC control.
- Hygienic design compliant with global food safety standards.
