PURPOSE:To obtain a high-protein, high-calcium and high-iron-contg. composite sour milk food by incubating lactic bacteria, in the presence of an iron compound, in hydrolyzate produced by enzymatic digestion of a soybean-ground product, cow milk-dried product or a mixture thereof. CONSTITUTION:A skin-removed raw soybean-ground product, cow milk-dried product such as skim milk or whey powder, or a mixture thereof is put to enzymatic digestion. Thence, in the presence of an iron compound, i.e., ferric citrate or ferrous lactate, the hydrolyzate produced by the above enzymatic digestion is inoculated with lactic bacteria, which is then proliferated, followed by further fermentation. Thereby, said iron component is drawn into the lactic bacteria, thus obtaining the objective sour milk food causing no adverse health effects due to the continuous intake of the iron salt to be subjected to complex formation through fermentation. |
