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.
