Abstract

PURPOSE: To improve the freshness-keeping effect of food preserved in a package or a container, by compounding an oxygen absorbent, a hygroscopic substance and/ or deliquescent substance which exhibits acidity when reacted with water, and a carbonate and/or a bicarbonate.
CONSTITUTION: An agent for keeping the freshness of food is prepared by mixing (A) an oxygen absorbent such as iron powder, its partial oxide, a ferrous compound, an inorganic reducing substance, etc., (B) hygroscopic substance which exhibits acidity when reacted with water, and/or a deliquescent substance which exhibits acidity when reacted with water, e.g. an acid anhydride such as phosphoric acid anhydride, sulfuric acid anhydride, etc., a halogenic acid salt or an oxygen acid salt of Fe, Co, Ni, Cu, etc., and (C) a carbonate and/or a bicarbonate. Each component may be pulverized and used as a powder mixture, or the mixture may be formed to pellets or beads with a tabletting machine, etc.
