摘要： A method for removing tannins from liquid fruit drinks, vegetable drinks, and fermented liquids of vegetable and fruit origin which comprises contacting the liquid with at least one highly dispersed polymer obtained by condensing a monomer selected from the group consisting of polyamino compounds, polyhydroxy compounds and mixtures thereof, with formaldehyde. Polymers useful in the method of the invention should have a specific surface area of over 20 m.sup.2 /g and a positive zeta potential in a solution having a pH of from 3 to 5. The polymers of the invention may be easily separated from the contacted liquid using standard filtration techniques.
