Fermentation Science Behind HYOSODAMEUN

At Yang Hyo Dang in Yecheon, Korea, we approach fermentation as applied science. Every batch is built to be reproducible.

• 100% plant-derived starter cultures, developed in-house with no animal or synthetic media.
• Multi-stage fermentation protected by Korean Patent No. 10-1747313. We keep the process details private.
• Stability testing including a 70°C x 80 hour stress test and repeated freeze-thaw cycles, plus long-term room-temperature storage monitoring.
• Independent lab reports from the Korea Food Research Institute and the Gyeongbuk Institute for Bio Industry.

The result is a smooth, consistent flavor from one batch to the next, which matters to us and to the importers we work with. See our For Buyers page for details.
