We are a specialized research center focusing on lactic acid bacteria fermentation, grain fermentation, and patented ingredient development.

Timeless values for better health and a better life
Fermented Immunity Research Institute is a corporate entity established to develop premium-quality raw materials for high-grade products. It was founded in October 2021 as a joint venture between fermentation expert Dr. Joo Yeong-cheol and You In-tak, CEO of Changui C&R. We are committed to combining traditional fermentation techniques with modern biotechnology to promote healthier foods.
Since 1982, Dr. Joo, a lactic acid bacteria specialist, and the researchers at Changui C&R have remained dedicated to this path. By leveraging lactic acid bacterial fermentation, grain-based fermented ingredients, and patented materials, we strive to keep our bodies’ cells healthy and full of vitality.
Fermentation Research for the Ones I Love Fermented foods and healthy lifestyle habits can greatly help our bodies build the strength to fight off illness on their own. We hope that these wholesome fermented foods will serve as a sort of “health coach,” invigorating your day. Moving forward, we will continue to develop beneficial fermented foods and lead a healthier culinary culture. | ![]() Dr. Joo Yeong-cheol (Director of the Research Institute) Seoul National University Bachelor’s, Master’s, Bachelor’s Food Science & Biotechnology / Agricultural Biotechnology Current Positions
