University of Siena, represented by the Regione Toscana Ufficio Regionale di Trasferimento Tecnologico, has been featured in Inpart Top 25 Innovations for 2025 article, which identifies those technologies that are most likely to have the biggest impact across science and R&D in the coming year.

The Hydroalcoholic Extract from Chestnut Shell for Use as an Antibacterial technology (ref: ChesnutExtract_Siena) is one of the technologies that received the most interest from R&D-driven companies using Inpart platform to find new partners over the past year.

Researchers from the Department of Biotechnology, Chemistry and Pharmacy coordinated by professor Annalisa Santucci, have extracted a special mixture from sweet chestnut shells with antibacterial and antimicrobial properties. Their mix, extracted with a hydroalcoholic solution, can be used as a preservative or antibacterial additive in food or animal feed production, to sterilize packaging and materials, and as a phytopharmaceutical potentiator in combination with existing treatments. The researchers’ invention is secured by a patent and industrial partners are sought for collaboration and commercialization.
