Tannic acid is a clarifying agent of beer and low alcohol wine, also used in pineapple proteinase food fields.
Both Beer-mashing and Beer Brewing Tannin are high pure tannic acid extracted from Chinese gallnut with physical method. They can reduce aldehydes in beer, enhancing non-biology stability and flavor stability of beer.
Beer-mashing tannin acid is suitable to brewage saccharification or in boiling process, adsorbing high polymer protein in wort, enhance beer antioxidant capacity.
Beer Brewing Tannin is suitable to brewage fermentation, storage and filtration, adsorbing high polymer alkaline, sulfur-containing and hydrophobic sensitive protein in beer.
Packing: 25kg/paperboard drum.
Storage: Avoid moisture and light; sealed in storage.
Add: Kaide Industry Park, Jiangkou , Guizhou, China.
