Abstract
Crosspure polymer, developed by BASF, is a new filter aid that is
used for the simultaneous filtration and stabilization of beer. Crosspure
is an alternative to diatomaceous earth (DE) or membrane filtration and
has the ability to stabilize beer through the removal of polyphenols.
Unlike diatomaceous earth, and other single-use stabilization aids,
Crosspure polymer is made to be regenerated and used repeatedly, which
helps to significantly reduce storage, handling, and disposal costs
normally associated with single-use filter aids. In addition, Crosspure
polymer can also be used on existing diatomaceous earth filter lines.
Minor modification of the filter line is required to use this
environmentally sustainable product. The product is cost-effective and has
the additional benefit of being a consistent, synthesized product with a
virtually zero metal uptake.

S�ntesis
El pol�mero �Crosspure� desarrollado por la BASF es
un nuevo adyuvante de la filtraci�n para la simult�nea filtraci�n y
estabilizaci�n de cerveza. �Crosspure� es un adyuvante alterno a la tierra
diatom�cea y a la filtraci�n por membranas, estabilizando la cerveza
mediante la remoci�n de polifenoles. A diferencia
de la tierra diatom�cea y otros adyuvantes de un solo uso, el pol�mero
Crosspure puede ser regenerado y utilizado repetidas veces, lo que reduce
significativamente el manejo, almacenaje y costo de disponer del adyuvante
usado. El pol�mero Crosspure, un producto sustentable ecol�gicamente,
puede ser utilizado en filtros existentes para tierra diatom�cea, con una
peque�a modificaci�n en la tuber�a. El producto reduce los costos,
con la ventaja adicional de ser un producto sint�tico consistente con un
aporte despreciable de metales al producto.
