Surface activity of protein extracts from seed oil by-products and wettability of developed bioplastics

Protein concentrates, extracted from the by-products of Hemp (Cannabis sativa), Cardoon (Cynara cardunculus), and Argan (Argania spinosa L.) oilseeds after oil extraction, were utilized to produce sustainable and eco-friendly protein-based bioplastics. The surface wettability and roughness of these...

Zusammenfassung:Protein concentrates, extracted from the by-products of Hemp (Cannabis sativa), Cardoon (Cynara cardunculus), and Argan (Argania spinosa L.) oilseeds after oil extraction, were utilized to produce sustainable and eco-friendly protein-based bioplastics. The surface wettability and roughness of these bioplastics were investigated due to the pivotal role of these parameters in their application in food packaging sector. Advancing contact angle value revealed that Argan protein-based bioplastic is the most hydrophobic (θ > 90°) while Cardoon protein-based film is the most hydrophilic (θ 45 mN m−1) at both pHs, while Argan and Hemp proteins displayed lower values than Cardoon, especially at pH 12 (
