An object of the invention is to provide a lactic acid bacteria fermentation product, which has been obtained by culturing lactic acid bacteria on a medium containing an extract of at least one food material selected from the group consisting of rice bran, persimmon leaves, perilla, Houttuynia cordata Thunb, Eucommia ulmoides Oliv., turmeric, clove, cinnamon and Rubus suavissimus S. Lee (Rosaceae). By adding and mixing the extract used for the preparation of the fermentation product to a medium, it is possible to increase simply the viable cell count of lactic acid bacteria, without affecting the flavor of the product. It is possible, by using the extract, to obtain a lactic acid bacteria fermentation product which contains many viable lactic acid bacteria with their activities highly maintained, and further to provide beverages or foods using the product.
