Influence of a Transparent and Edible Coating of Encapsulated Cannabidiol Nanoparticles on the Quality and Shelf Life of Strawberries

Cannabidiol (CBD) has been shown to have antioxidant and antibacterial effects. The investigation into CBD's potential as an antioxidant and antibacterial agent, meanwhile, is still in its initial stages. The study goals were to prepare encapsulated cannabidiol isolate (eCBDi), evaluate the effect of eCBDi edible active coatings on the physicochemical properties of strawberries, and determine whether CBD and sodium alginate coatings could be used as a postharvest treatment to promote antioxidation and antimicrobial activity and prolong the strawberry shelf life. A well-designed edible coating on the strawberry surface was achieved using eCBDi nanoparticles in combination with a sodium alginate polysaccharide-based solution. Strawberries were examined for their visual appearance and quality parameters. In the results, a significantly delayed deterioration was observed in terms of weight loss, total acidity, pH, microbial activity, and antioxidant activity for coated strawberries compared to the control. This study demonstrates the capability of eCBDi nanoparticles as an efficient active food coating agent.
