Abstract:
The invention is directed to a precoat or body feed composition comprising a microbiological interception enhanced filter aid. Preferably, the microbiological interception enhanced filter aid comprises fibrillated lyocell nanofibers having coated on at least a portion of a surface thereof, a microbiological interception enhancing agent. The microbiological interception enhanced agent comprises a cationic material in combination with a biologically active metal. At least about 4 log reduction in bacterial interception is achieved with the microbiological interception enhanced filter aid alone or in combination with a bulk, untreated filter aid. A precoat composition including the microbiological interception enhanced filter aid can be used for one-step cold sterilisation of beverages.
