Origin & History
Cheonggukjang is a traditional Korean fermented soybean paste (Glycine max) made by fermenting boiled soybeans with Bacillus subtilis. It is a revered staple in Korean cuisine, recognized for its potent probiotic content, deep umami flavor, and bioactive compounds. This makes it highly valued for its significant contributions to functional nutrition.
“Cheonggukjang has been a cornerstone of Korean cuisine and traditional wellness for centuries, developed as a fast-fermenting alternative to Doenjang. Historically consumed during winter for its fortifying and warming properties, it symbolizes resilience and health within Korean culture. Its traditional applications highlight its role in nourishing the body and supporting vitality.”Traditional Medicine

Frequently Asked Questions
What is cheonggukjang?
Cheonggukjang is a traditional Korean fermented soybean paste made by fermenting boiled soybeans with Bacillus subtilis bacteria for 2-3 days. It is prized for its potent probiotic content, rich umami flavor, and bioactive isoflavones, peptides, and vitamin K2.
How much cheonggukjang should I eat daily and is it safe?
Traditional consumption is 1-2 tablespoons per meal in soups or stews. It is generally safe as a food, but its high sodium content requires moderation for those with hypertension. People on blood thinners or MAO inhibitors should consult a physician due to fibrinolytic enzymes and potential tyramine content.
How does cheonggukjang differ from doenjang or natto?
Cheonggukjang ferments for only 2-3 days (vs. months for doenjang), resulting in a stronger, more pungent flavor and higher Bacillus subtilis probiotic counts. It is similar to Japanese natto in its Bacillus-driven fermentation but is consumed as a paste rather than whole sticky beans, and typically has a more intense aroma.
