TANNOX-BREW
TANNOX-BREW is an atomized granulate powder of a high purified high molecular weight gallotannin. Gallotanins or tannic acid are extracted from gallnuts. Tannic acid inhibits malt lipoxygenase activity by 50%, reduces metals by its reducing power, removes metals by its chelating power and blocks radicals forming reactions. Tannic acid reacts very selectively with acid proteins containing SH-groups. Only these sensitive proteins are removed. TANNOX-BREW gives a real improvement on lauter-tun or mash-filter filtration rates and improves beer shelf life as far as clarity, taste and flavour are concerned.

ADDITION |
- During mashing-in the addition of TANNOX-BREW will improve the wort filtration rates, will reduce the malt lipoxygenase activity reducing fatty acids oxydations and radicals formation, will improve ITT or anti-oxydation power.
- At the end of boiling (5 minutes before the end to avoid tannic acid hydrolysis) will improve colloidal stability, whirlpool yield and ITT. |
| |
|
USE RATE |
4 to 8 g/Hl at mash in and 4 to 8 g/Hl at end of boiling. |
| |
|
BENEFITS |
- Better wort filtration rate.
- Longer beer shelf life: by lipoxygenase reduction, by metals reduction, by metals removing, by improving ITT.
- Colloidal stability improvment.
- Whirlpool yield increase. |
