Deoxidizing agent

Abstract

Abstract PURPOSE: A mixture of cast iron powder, aqueous ferric iron solution, deoiled soybean powder, and stone powder provides a highly efficient deoxidizing agent with reliable service life. CONSTITUTION: One part by weight of aqueous saturated solution of ferric chloride is adsorbed by 5 to 6 parts by weight of deoiled soybean powder of about 500 mesh and uniformly mixed with 1 to 6 parts by weight of stone powder such as talc of about 400 mesh. The mixture is then added with 2 to 12 parts by weight of cast iron powder of about 200 mesh having 3.5 to 4.5 wt% of carbon to form a deoxidizing agent. Then so formed product is devided in a constant quantity and packed in gas permeable bags to be used in closed food containers, providing excellent deoxidation effect with high reliability.
