Green Extraction of Lignin From Date Palm ( Phoenix dactylifera L.) Seed Waste and Its Integration Into Alginate‐Based Films With Improved Moisture Resistance, Antioxidant Capacity, and Surface Hydrophobicity for Food Packaging Applications
The aim of the current study was to extract lignin‐rich fraction from date palm ( Phoenix dactylifera L.) seeds and evaluate its application as a filler in sodium alginate‐based films for food packaging applications. Lignin was isolated through a sonication‐assisted mild alkaline hydrolytic process followed b...
