Protosol 5kg

Protosol is a highly effective colloidal silica sol which provide an efficient and cost-effective solution for clarifying beer and wort.

Key Benefits

• Highly effective clarification helps increase brewery throughput without investment in additional tank or filtration capacity.
• Low addition rate is cost-effective.
• Protosol is a processing aid so is not required to be listed on labels.
• Does not contain animal derivatives.
• Beer filterability is enhanced due to removal of solids.

How it Works

Protosol is a specifically selected colloidal silica sol which promotes sedimentation of proteins and other solids from beer and wort. The negatively-charged silica particles in Protosol associate to form hydrogel in the beer, which then interacts with the insoluble haze-forming particles. The resultant flocs precipitate to form sediment.

Application & Dosage

Protosol is typically added to beer at rates in the range 20–200ml/hl.

The level of solids in the beer will determine the required addition rate. The correct addition rate is best identified by performing a lab-scale optimisation test and assessing for clarity and sediment compaction.

Protosol can be added to chilled beer in-line during transfer from fermenter to maturation tank, to ensure thorough mixing with the beer.
