Frequently Asked Questions
What is doenjang?
Doenjang is a traditional Korean fermented soybean paste made by fermenting meju (soybean bricks) in brine for months to years. The extended fermentation produces beneficial probiotics, bioactive isoflavones, peptides, and vitamin K2, making it both a culinary staple and a functional food.
How much doenjang is safe to consume daily?
Typical culinary use is 1-2 tablespoons per meal. The primary safety concern is its high sodium content (approximately 4,000-5,000 mg per 100g), so intake should be moderated, especially for individuals with hypertension or kidney disease. Those on blood thinners should maintain consistent intake due to vitamin K content.
How does doenjang compare to miso?
Both are fermented soybean pastes with probiotic and isoflavone benefits. Doenjang typically undergoes a longer, more robust fermentation using meju blocks and brine, resulting in a stronger, earthier flavor and potentially higher concentrations of certain bioactive metabolites. Miso often includes grain (rice or barley) koji, giving it a milder, sweeter profile.
