1. one kind is improved the method for the fragrance composition of biological fermentation solution in beer and beer-like beverage preparation, it comprises and comprises after fermentation by every 100 liters of biological fermentation solution 1-3000g the other copolymerisable monomer the polymer treatment of producing when there is not oxygen and polymerization starter and under the linking agent based on monomer being 0.5-10 % by weight exists that 50-99.5 % by weight N-vinyl imidazole and 0-49.5 % by weight introduced by polymerization, wherein in the process, carry out with the time point that polymer treatment is still forming fragrance, and present method does not substitute subsequent filtration by for removing compared with the filter for installation of coarse particles or cell rests thing, also silica is not used, cross-linking polyethylene pyrrolidone and similar substance substitute stabilization.
