PURPOSE:To reduce the generation of aldehydes when the titled deoxidizer is jointly used with an alcoholic food preserving agent by mixing an iron component having deoxidizing capability and a polyamino acid or a polymer contg. an amino acid to prepare the deoxidizer. CONSTITUTION:An iron component having deoxidizing capability and a polyamino acid or a polymer contg. an amino acid are mixed, and the mixture is enclosed in a gas-permeable bag to prepare the deoxidizer. The deoxidizer is composed of 100pts.wt. iron component having deoxidizing capability and >=0.2pt.wt., preferably 1-20pts.wt., on a dry weight basis of the polyamino acid or the polymer contg. an amino acid. Reduced iron powder, electrolytic iron powder, sprayed iron powder, etc., are appropriately used as the iron component having deoxidizing capability. Polysaccharides consisting of amino acids such as chitin and chitosan can be exemplified as the polymer contg. an amino acid.
