Tannic acid(Beer brewing,saccharification type)
Tannic acid(Beer brewing,saccharification type)
CAS NO: 1401-55-4
It is a high-purity tannic acid extracted from Gallnut by pure physical method.
It is suitable for the saccharification or boiling process of beer brewing,
It can selectively adsorb high molecular weight protein in wort, reduce aldehydes in beer,
Enhance the antioxidant capacity of beer. Improve beer non-biological stability and flavor stability.

Instructions:
Need to use deoxygenated brewing water or distilled water to prepare a 5-10% tannin solution before use.
Adding in saccharification: add the diluted tannin solution to the saccharification water before adding the malt powder.
Recommended dosage: 40-80ppm
Add in the boiling pot: 5-10 minutes before the end of boiling: or add in the wort transfer wort clarifier pipeline.
Recommended dosage: 30-60 ppm.
Preparation method:
Use a stainless steel container or a plastic container, pour deoxygenated water or distilled water at room temperature, and stir quickly. When a vortex is formed, slowly pour the tannin for saccharification into the container, and stir while pouring to make it completely dissolved to 20- 25% solution. Before use, dilute to 5-10% solution. Try to avoid contact with oxygen. Avoid using iron, aluminum and other containers and utensils
