Tsukemono with fermentation is fermented by the lactic bacterium naturally attached to the ingredients and the sugars included in the ingredients, which enhance the quality of preservation, taste and flavor; moreover, sugars as ground substances for fermentation can be increased by adding rice malt, and the oxygen reaction needed to improve taste and flavor can be induced by the enzyme contained in rice malt.
