At the Yakult Central Institute, safety evaluation processes are essential for development of food, cosmetics, and healthcare products, and various safety tests are conducted appropriately and rigorously using internationally standardized testing methods. The Quality Assurance Unit plays a crucial role in objectively ensuring the reliability of these tests by reviewing their contents and data from a third-party perspective. Additionally, it is responsible for auditing the production system for manufacturing seed cultures, which are regularly dispatched from the Yakult Central Institute to overseas plants.
　The Yakult Central Institute also carries out a wide range of other research activities. Given the importance of each researcher's ethical standards and quality control of research data, the unit also engages in providing training programs aimed at promoting ethics and integrity in research practice.
