【Abstract】 The synthetic conditions of Chromium-Methionine chelate as food additives was studied with an emphasis on the effects of the molar ratio of ligand and pH on the chelating reaction. The optimum technologic conditions for the synthesis were found as follows: the molar ratio of methionine to chromium was 3∶1; reaction pH was 7.0; reaction temperature was 80℃. The yield of product was 48.41%.更多还原
