Abstract

This article focuses on the extraction and chemical modification of sodium alginate from the brown alga Cystoseira stricta, harvested from the Algerian coast, for potential application in food preservation. Sodium alginate was successfully grafted with maleic anhydride to produce maleated sodium alginate, which exhibited improved thermal stability, antioxidant activity, and lighter color compared to the native polymer. A nanoemulsion combining maleated sodium alginate and date seed oil was formulated and applied as an edible coating on strawberries, effectively delaying spoilage and extending shelf life at ambient temperature. The study demonstrates that maleated sodium alginate-based nanoemulsions could serve as eco-friendly, functional coatings to enhance the preservation of fresh fruits.
