Tannins are a class of polyphenolic compounds that are widely found in plant tissues. This kind of substance seriously endangers human health. For example, food contains excessive tannin, which is not only easy to change color, has astringency, affects appetite, but also can print digestive enzyme activity, reduce vitamin, mineral, protein absorption and cause gastroenteritis. , digestive tract congestion, liver damage and other symptoms. Therefore, the removal of tannins is of great significance.
The macroporous adsobent resin provided by Suzhou Bojie Resin Technology Co., Ltd. has high efficiency selective adsorption on tannin molecules. The molecular size of tannin is relatively large, and the diameter is about 1.6 nm. The pore size of the special resin for tannin adsorption is suitable and does not destroy. A useful substance, without introducing other impurities, has a low residual organic solvent, and achieves a good tannin adsorption removal effect. The resin has large adsorption capacity, high mechanical strength, recyclable and reusable, simple operation conditions, and considerable economic benefits.
