COMPAC CG
Compac CG is the semi-refined, granulated form of the seaweed species Eucheuma cottonii.
The species Eucheuma cottonii is rich in the kappa isomer of carrageenan.
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 solution. The clear wort that results produces a beer with enhanced processing characteristics.
Improved hot break compaction
Improved filtration
Improved yeast vitality
Compac CG is typically added to wort at rates in the range 1–3g/hl. Variations in grist make-up, malt quality, brewing liquor, and plant operation all have a major impact on the carrageenan requirement. The correct addition rate is best
identified by a simple optimization test (see DATA SHEET).
