Food spoilage, which often leads to food waste, occurs throughout the entire supply chain, from upstream downstream stages of production. Biobased hydrogels made cellulose nanofiber (CNF) have emerged as potential materials for extending shelf-life. Despite this potential, impact defibrillation time during production CNF on properties CNF-based (CNF-H) has not been thoroughly investigated. In study, was varied at 50–90 min examine its effect both itself and resulting hydrogel properties. The findings revealed that longer mechanical times significantly reduced size CNF, leading a denser CNF-H structure. At extended times, diameter decreased 25 20 nm, strengthened inter- intramolecular forces between fibers, in more crystallinity (from 66.64% 77.51%) compact network. This structure water absorption capacity, thereby limiting moisture penetration decreasing biodegradability. Additionally, antimicrobial activity CNF-H, tested after soaking ethanol, showed enhanced effectiveness against gram-positive gram-negative bacteria with increased time, all without exhibiting cytotoxic effects.
