Protafloc Tablets are the semi-refined, granulated form of the seaweed species Eucheuma cottonii

When added to boiling wort, kappa carrageenan reacts strongly with soluble proteins, notably the proline-rich haze precursor fraction. When the wort is cooled, the carrageenan-protein complex becomes unstable and precipitates out of the solution. The clear wort that results produces a beer with enhanced processing characteristics.

Benefits Include

• Improved hot break compaction in the whirlpool.
• Improved yeast vitality during fermentation.
• Improved filtration – longer filter runs.
• Improved beer haze and colloidal stability.
  

Protafloc Tablets are typically added to the wort at 1–3g/hl rates. Variations in grist makeup, malt quality, brewing liquor, and plant operation greatly impact the carrageenan requirement. A simple optimisation test best identifies the correct addition rate.

Principle

When added to boiling wort, kappa carrageenan reacts strongly with soluble proteins, notably the proline-rich haze precursor fraction. When the wort is cooled, the carrageenan-protein complex becomes unstable and precipitates out of the solution. The clear wort that results produces a beer with enhanced processing characteristics.

Treatment Rates

Protafloc Tablets are typically added to the wort at rates in the range 1–3g/hl. Variations in grist makeup, malt quality, brewing liquor, and plant operation all greatly impact the carrageenan requirement. A simple optimisation test best identifies the correct addition rate (see later).

Identification of Optimum Addition Rate

1. Prepare a solution of Protafloc Tablets in hot water. Example: add 0.5 g Compac CG to 500ml boiling water.
2. Stir for 10 minutes.
3. Add the solution to a series of clear glass containers to give a range of treatment rates. Example: to 100ml containers, add 0,1, 2, 3, 4 and 5 ml of solution. This will give an additional rate range of 0 to 5g/hl.
4. Sample wort from the kettle at the end of the boiling period, and whilst still hot, add to the pre-dosed bottles.
5. Mix well,seal, and allow to stand for an hour. Cool in cold water and allow to stand overnight.
6. Assess results by observing the clarity of the wort and the sediment volume. The optimum result is obtained by identifying the addition rate at which a combination of clarity and low sediment volume is found.
7. The results can be interpreted by measuring the haze or turbidity of the wort.
