Kimchi is a traditional fermented vegetable food in Korea and is known to be a product fermented mainly by lactic acid bacteria. The major raw material (oriental cabbage or radish) is salted after pre-brining, blended with various ingredients (red pepper, garlic, green onion, ginger, salted seafood, fruits and vegetables, cereals, fish and etc.), and then fermented. Kimchi has a unique sour, sweet, and carbonated taste. It differs from sauerkraut and pickle with a distinctive sour taste, which are popular fermented-vegetable products in the West (Cheigh & Park, 1994). Kimchi is a natural lactic acid-fermented food, which can be acidified due to the production of lactic acid by lactic acid bacteria and enzymes during distribution.
