A B S T R A C T The present invention relates to an atmosphere modifier making use of an oxygen-removing, carbonic acid gas generating material such as ascorbic acid or the like. Objects thereof are to improve the packing suitability to packaging materials, to shorten the time taken for achieving an anaerobic atmosphere, and to make it possible to adjust in the desired range the oxygen concentration and carbonic acid gas concentration in an anaerobic atmosphere being adjusted. For this purpose, in the atmosphere modifier of the present invention, a carbonic acid gas generating agent, a ferrous compound, a pH adjuster and water are dispersed in a dispersion medium comprising silicon dioxide and/or calcium silicate, crystal cellulose, and activated carbon optionally used. Preferably, ascorbic acid or calcium carbonate is used as the carbonic acid gas generating agent, depending on the gas composition of the desired anaerobic atmosphere, and calcium hydroxide and/or sodium carbonate is/are used as the pH adjuster.
