    摘要: A sealed package for inhibiting the oxidation and spoilage of raw meat or fish, while maintaining the scarlet color of the raw meat or fish. This package comprises an impermeable vessel housing a deoxidant-CO.sub.2 generating agent composition together with the raw meat or fish. The deoxidant-CO.sub.2 generating agent composition is selected to generate CO.sub.2 gas immediately after the initiation of O.sub.2 absorption at the rate of 0.2 to 2 mols per mol of O.sub.2 absorbed.
