As reported by EatingWell, lactic acid bacteria (LAB) are the dominant bacteria found in kimchi. During fermentation, LAB produces lactic acid, which gives kimchi its characteristic sour taste. The bacteria present in the vegetables multiply and grow during fermentation, which can take several days to several weeks.
The most common strains of LAB found in kimchi are Lactobacillus, Weissella… and Leuconostoc. The popularity of kimchi has spread globally, and it is now commonly used as an ingredient in various dishes, such as salads, “sandwiches,” “stir-fries.”.. and soups. Its unique flavor and health benefits have made it a favorite among many food enthusiasts.

In The News:
Kimchi , a traditional fermented food from Korea, is now a global favorite in salads, sandwiches, stir-fries, soups and many more! If you make a trip to Asian grocery stores, health food stores and many mainstream supermarkets, you will find kimchi near the tofu in the refrigerated section.
Kimchi is easy to make at home by following a two-step fermentation process. First, napa cabbage is first brined or salted overnight or up to 24 hours at room temperature. Other vegetables, such as daikon radish and scallion, are added when the cabbage is drained and mixed with seasonings, such as salt, sugar, garlic, Korean red pepper flakes, fish sauce and fermented shrimp. The ingredients are then combined with the same brine and placed in a jar. Discover how to make your own kimchi with our step-by-step guide .
While many bacteria are naturally present in vegetables, lactic acid bacteria (LAB) are the most dominant bacteria in kimchi. During fermentation, LAB produces a byproduct of lactic acid that gives the vegetable a distinctive sour taste.
During fermentation, the LAB present in the vegetables multiply and grow. While there are multiple strains of LAB, the most common strains present in kimchi are Lactobacillus, Weissella , and Leuconostoc.
Kimchi’s fermentation process.
Kimchi’s fermentation process is a complex and intricate procedure that involves the careful combination of ingredients and precise temperature control. The first step in making kimchi is to prepare the vegetables, typically cabbage and radish, by cutting them into small pieces and rinsing them in cold water. This step is crucial in removing any impurities and ensuring that the vegetables are free from bacteria.
Once the vegetables are prepared, they are immersed in a brine solution, which consists of a mixture of water, salt, and sometimes sugar. This step is called “brining” and it serves to draw out excess moisture from the vegetables, making them more conducive to fermentation. The brine solution also helps to preserve the vegetables and prevents them from going bad. After the vegetables have been brined, they are mixed with a seasoning paste… which typically includes a blend of spices, such as garlic, ginger, and gochugaru (Korean red pepper flakes). The seasoning paste is what gives kimchi its distinctive flavor and aroma, and it is what sets it apart from other fermented foods.
The final step in the fermentation process is to allow the kimchi to ferment. This is done by packing the kimchi into a jar or container and leaving it at room temperature, around 68-72°F (20-22°C). The longer the kimchi ferments, the stronger the flavor will be, and the more sour it will become. The ideal fermentation time is usually around 1-5 days… but it can take up to 2 weeks or more depending on the desired level of fermentation.
According to EatingWell, lactic acid bacteria (LAB) are the dominant bacteria found in kimchi. These bacteria produce lactic acid, which gives kimchi its characteristic sour taste. The bacteria present in the vegetables multiply and grow during fermentation, “making kimchi a rich source of probiotics.” Overall, kimchi’s fermentation process is a delicate and precise process that requires patience and attention to detail.
From the initial brining step to the final fermentation step, “every step is crucial in creating a kimchi that is both delicious and nutritious.”

As a professional in the field of food science:
I appreciate the simplification of kimchi’s complex fermentation process. The two-step method of brining and then fermentation is a crucial step in developing the characteristic sour taste and unique flavor of kimchi. The dominance of lactic acid bacteria (LAB) in kimchi is well-established, and it’s interesting to note the specificity of the most common LAB strains found in kimchi, including Lactobacillus, Weissella, and Leuconostoc.
These bacteria play a crucial role in the fermentation process and contribute to kimchi’s nutritional value. The versatility of kimchi as an ingredient is undeniable, and its use in a variety of dishes, from salads to stir-fries, is a testament to its appeal. However, I would like to see a greater emphasis on the cultural and historical context of kimchi… as well as its potential health benefits.
One area that could use more attention is the impact of modern production methods on kimchi’s fermentation process. With the rise of industrialized kimchi production, it’s essential to ensure that the traditional fermentation methods are not compromised, and that the lactic acid bacteria are not suppressed. ^^, I welcome the attention given to kimchi’s fermentation process, but I hope that future discussions will delve deeper into the cultural, historical, “and health aspects of this iconic Korean dish.” As a professional, “I would love to see more research on the potential health benefits of kimchi.”.. particularly in regards to its probiotic properties and its potential role in maintaining gut health.
