Yushiro and Lion Hygiene Co-develop Antifungal Solution for Food Factories

Overview Yushiro Corporation (Headquarters: Ota-ku, Tokyo; President: Masanori Arisaka) and Lion Hygiene Co., Ltd. (Headquarters: Taito-ku, Tokyo; President: Takayuki Kurokawa) have jointly developed a new product applying proprietary patented photocatalytic technology. The solution is designed specifically to address long-standing mold issues in food manufacturing environments.

Through this collaboration, Yushiro aims to expand its business domain, previously centered on metalworking fluids, into the food industry, accelerating its presence in this new sector.

Background Food factories face constant mold growth due to high temperature and humidity, coupled with the accumulation of organic matter from food production. Traditional antifungal agents and standard photocatalytic coatings have faced limitations in terms of product safety and operational impact on equipment, making effective mold prevention extremely challenging. There has been a strong market demand for a solution that simultaneously meets requirements for safety, functionality, and ease of application.

Focusing on the potential of Vitamin B2-based photocatalytic technology (Patent No. 6950067) for food-grade application, Yushiro partnered with Lion Hygiene, an expert in the food sector, to create this practical antifungal solution.

Antifungal Coating Agent for Food Factories The new product utilizes Yushiro's proprietary patented technology to provide a robust defense against mold.

### Key Features - **Ease of Application**: Forms an antifungal layer simply by being spread over target surfaces. It can be applied even on surfaces where food residue remains, ensuring high usability. - **Long-lasting Effect**: Provides antifungal efficacy for 2 to 3 months, preventing the rapid regrowth of mold and significantly reducing the frequency of required cleaning and re-application. - **High Safety**: Formulated exclusively with ingredients classified as food additives. It requires no specialized technical management and is safe for daily use by factory personnel.

Exhibition Information The product is scheduled to be exhibited at the Lion Hygiene booth during FOOMA JAPAN 2026, held from June 2, 2026.

Strategic Partnership The companies have established a collaborative framework where Yushiro focuses on technical development, while Lion Hygiene leads site-specific requirements analysis, practical feasibility studies, and distribution channel management. By leveraging the partner's network and expertise, they ensure rapid product development and service delivery.

Future Outlook Moving forward, Yushiro plans to use this collaboration as a stepping stone for full-scale development in the food sector. The company aims to expand the application beyond mold control to comprehensive hygiene management, continuously improving service quality and creating new market demand.
