Description
Kimchi fermentation with alternative vegetables relies on lactic acid bacteria to lower pH and develop complex flavors, with salt and temperature carefully controlled to prevent spoilage.
Technical
During fermentation, Lactobacillus plantarum and Leuconostoc mesenteroides convert sugars into lactic acid, lowering the pH to 4.0–4.5 within 24–48 h. The acidic environment inhibits spoilage microbes while enzymes break down plant cell walls, releasing glutamate and sulfur compounds that contribute to umami and pungency. The rate of acidification and flavor development is governed by salt concentration, temperature, and fermentation time.
