The method and apparatus for accelerating growth of lactic acid bacteria, which apply an electric field to the lactic acid bacteria using an electric field in a frequency band of 1 kHz to 1 MHz, can be applied to all lactic acid bacteria used in home and industries to accelerate the growth of them and can be used to increase the number of the lactic acid bacteria and the production of all metabolites (for example, lactic acid and carbon dioxide) of the lactic acid bacteria. The invention increases the lactic acid bacteria and the production of the metabolites of the lactic acid bacteria, thereby activating the beneficial fermentation action of the processed foods such as fermented milk, lactic acid bacteria-containing beverage, toenjang or salted foods (kimchi or pickle and the like). In addition, the invention lowers pH of the foods to suppress the proliferation of the harmful microbes, and makes the low oxygen/oxygen-free environment using the carbon dioxides produced as metabolism by-products, thereby increasing the flavor of the foods and prolonging the preservation period.
