Koiwai Dairy Products

Koiwai Dairy Products is a prominent Japanese dairy company that operates as a joint venture between Kirin Holdings and Koiwai Farm. While primarily known for high-quality milk, yogurt, and cheese, the company is a significant player in the health science sector through its focus on functional foods and fermentation technology. In collaboration with Kirin, Koiwai has been instrumental in the research and commercialization of Lactococcus lactis strain Plasma (LC-Plasma), a postbiotic ingredient designed to support the immune system. This specific strain is the first in Japan to be labeled for immune function support under the Food with Function Claims (FFC) system. The company's business model integrates traditional dairy production with advanced biotechnological research to address consumer health and wellness needs.
