Crosspure®

Our Crosspure® Product Range

Crosspure® is a kieselguhr-free filtration aid for beverages such as wine or beer. Crosspure® improves clarity and stability with a pure taste, and long shelf life. Crosspure® filters and stabilizes your product in just one step. With more than 150 years experience in the human nutrition industry we are among the key partners for several beverage applications.

BASF offers you a wide range of products for optimum filtration and stabilization of beer, wine and other beverages.

Crosspure® is an innovative, regenerable polymer consisting of 70% polystyrene and 30% Polyvinylpyrrolidon (PVPP), which combine stabilization and filtration into one step. Crosspure® can adsorb polyphenols and hold back yeast, proteins, replacing kieselguhr and PVPP as filtration and stabilization aid.

Combine clarity with stability while eliminating kieselguhr

There’s more than one good reason for making Crosspure® your preferred choice when it comes to kieselguhr-free filtration and stabilization of beer: Crosspure® is regenerable, safe and easy to handle.

Filter and stabilize your product in just one step

In a technical process, haze particles like yeasts, complexes consisting of protein, and tanning agents are effectively removed. Using Crosspure® will result in a product that will fulfill all your customers’ demands for a crystal clear beverage. Crosspure® is not only regenerable, with virtually no limits, but it is the most sustainable filtration technology currently on the market. Therefore, a filtration free of kieselguhr is as healthy for your business as it is for your employees.

The Crosspure® 2-in-1 Effect: One-step filtration and stabilization

When filtering with Crosspure®, two separation mechanisms provide perfect clarity. Physical processes remove particulate substances causing turbidity such as yeasts, protein-tannin complexes, oxalates, and hops resins. In addition, dissolved tannins are adsorbed such as anthocyanogens and flavonoids.

Crosspure® Benefits

  • We provide with Crosspure® a safe and sustainable alternative for beverage filtration and clarification. Crosspure® is physically and chemically stable with a nonabrasive effect. Its recyclable properties make it an eco-efficient substitute for kieselguhr, which poses health hazards, is non-renewable, and requires careful product handling and disposal.
  • We developed a premium product range of user-friendly and highly effective products. The filter cake can be easily removed from the filter candles or filter elements. Crosspure® satisfies customer preference for clear beverages, and optimally reduces tannins. Crosspure® is an extremely versatile product, it can be used in existing regeneration systems with minor modifications. It is also possible to retrofit existing candles or ZHF filters with the regeneration system.
  • We support our customers to cut their losses. The Crosspure® filtration and regeneration cycle can be repeated almost endlessly. A maximum of 1% per regeneration is lost, with the recycled material showing consistent, high product quality you can count on. Only a minor investment is necessary to cut “classic” filtrations and stabilization costs.
  • We support our customers and partners with technical application services and product developments as well as tailor-made trainings in our globally linked Application Labs. Our experts offer traditional German brewing expertise combined with gained knowledge and competence in filtration and stabilization.

Regeneration of Crosspure®

Crosspure® is highly effective, extremely economical and environmentally friendly. After successful filtration, Crosspure®’s potential is far from exhausted:

  • Crosspure® is almost unlimitedly regenerable
  • Regeneration losses are less than 1 percent.

Crosspure® can be regenerated like PVPP in a combined filtration and regeneration system: a closed system comprised of a dosing unit, filter, and CIP system. This means it can be effectively regenerated in a multi-step process with already existing systems!
