Abstract
Zinc glutamate salts are obtained by (1) mixing an aqueous solution containing glutamic acid with zinc hydroxide at pH 5.5-11.0, or (2) mixing an aqueous solution containing glutamic acid and a zinc salt with sufficient alkali or alkaline earth metal hydroxide to bring the pH to 5.5-11.0; zinc-magnesium glutamate is obtained by mixing an aqueous solution containing magnesium glutamate with zinc hydroxide at pH 5.5-11.0. The above salts are all insoluble in water and can be separated from the solution. They are probably basic salts containing three metal ions, two glutamate ions and two hydroxyl ions per molecule. The zinc salt used in method (2) may be the chloride, phosphate, sulphate or acetate. When using crude solutions such as protein hydrolysates containing 0.1-10 per cent of glutamic acid, there are preferably used 8-10 mols. of zinc compound per mol. of glutamic acid. The precipitation of the zinc salt then forms a convenient way of isolating glutamic acid from the solution. Alternatively the salts may be made from refined glutamic acid when 1-2 mols. of zinc compound are sufficient. The preferred pH range for formation of the salt is 6.3-10.5, especially 8.5-9.5. Free glutamic acid may be obtained from the zinc salt by suspending it in water, adding an inorganic reagent which forms an insoluble zinc salt (e.g. sulphide or carbonate), filtering and crystallizing glutamic acid from the solution. Examples are given of the process.
