Pectin-Based Bioplastics Functionalized with Polyphenols from Rose Oil Distillation Wastewater Exhibit Antioxidant Activity.

This study explored the potential of rose aqueous extract (RE), a byproduct of rose essential oil extraction, to enhance the properties of biobased food packaging materials. RE contained a high phenolic content (153 mg of GAE/g of dw), rich in hydroxybenzoic acids and flavonols. The antioxidant potential of RE, assessed by DPPH assay, was evaluated (IC = 2.
