Preparation of low alcohol beverages by reverse osmosis |
摘要 |
A traditional flavored fermented alcoholic beverage of low alcohol content is prepared by reverse osmosis with a thin layer composite membrane which has a support layer of polysulfone, a barrier layer of polymer prepared from a polyamine and a polyacyl, and a fiber backing. The membrane has a molecular weight cut-off of less than about 100 for organics and rejects the volatile components which contribute to flavor and aroma and permits about 25 to about 30% alcohol in the beverage to pass.
