Postharvest spoilage of fruits accounts for significant losses ranging between 20 %–30 %, leading to considerable resource wastage and economic downturns. This study introduces an innovative on-demand removable active fruit fresh-keeping film (GPP), created by embedding a GP (gallic acid-phycocyanin) fiber mesh hydrogel with functional properties into a polyvinyl alcohol (PVA) matrix. These results underscore the potential of this hydrogel-based film as an invaluable material for fruit preservation within the food industry.
