摘要
A method for fermenting diacetyl and acetoin with a lactic acid bacterium by adding one or more additives selected from ferroporphyrin, heme protein, an animal tissue containing ferroporphyrin and blood and metal salts to a culture substrate containing a sugar source which a lactic acid bacterium can use, inoculating the lactic acid bacterium into the substrate and then aerobically culturing the bacterium with shaking or under aeration. A culture solution containing high concentrations of diacetyl and acetoin obtained by the present invention or its diacetyl concentrate is used to increase or improve the flavor of foods such as oils and fats, e.g., butter, margarine, cheeses, shortening, etc., confectionery, creams and the like.
