を失ってしまう。Ferrous salts are used as raw materials for pigment production and the textile industry, and divalent iron is known to have an excellent effect on removing bad odors such as ammonia and mercaptans due to its strong oxidizing power. It is being In addition, iron is an essential component for maintaining life that is involved in the oxygen transport redox mechanism, etc. in the living body, and is absorbed through the intestines in the form of divalent ferrous ions. Therefore, ferrous salts are also important as iron supplying agents.However, if ferrous compounds are left in a water-soluble state, 2
Since valent iron ions are extremely unstable, they combine with dissolved oxygen or oxygen in the air, are easily oxidized to trivalent ions, and lose their activity.

一鉄である。The ferrous hexose phosphate used in the present invention is a hexose, that is, glucose, fructose, mannose, galactose, tagatose, turdose, etc., and its derivatives such as fucose, quinovose, rhamnose, etc., in which one or more hydroxyl groups are replaced with a phosphate group. Preferred ferrous salts of substituted phosphate esters include ferrous glucose-1-phosphate, ferrous glucose-6-phosphate, and ferrous glucose-1,6-zophosphate. Examples include ferrous salts, among which ferrous glucose-1-phosphate is particularly preferred. This hexose rin I! ! The ferrous salt is obtained by, for example, reacting a neutral alkaline earth metal hexose phosphate with a neutral or acidic ferrous salt. If the ferrous ion anion is selected so that it is poorly soluble in water traps, it will be pale blue-green to colorless and transparent, weakly acidic (pH 6.0 to 6.5).
Moreover, it can be easily separated and obtained as a stable ferrous salt. The alkaline earth metal hexose phosphate used in this method includes barium, calcium, etc., but barium is preferred. Furthermore, neutral or acidic ferrous salts include ferrous sulfate, ferrous nitrate, and ferrous carbonate, with ferrous sulfate being preferred.
