Investigation of Potential Risks in Bio‐Based Food Contact Materials (FCMs) From Microbial Exploitation of Agricultural Wastes: Case Studies of Bacterial Cellulose and Nisin

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT In the context of the circular economy and the increasing demand for safe and sustainable packaging, this work addresses the safety assessment of food contact materials (FCMs) derived from agro‐industrial by‐products. Despite growing interest in these bio‐based materials, the literature still lacks a structured safety‐assessment framework able

Use of Computational Models to Investigate Human Targets of Small Ubiquitous Molecules

ChemBioChem, Volume 27, Issue 8, April 2026.
Chemoinformatics and atomistic modeling were combined to identify protein targets of environmentally and occupationally relevant chemical compounds. A public database linking chemicals, genes, phenotypes, and diseases was used for validation. The study highlights the potential and limitations of these fast, low‐cost computational approaches for early ...
