Unfortunately, significant inhibitory effects of chitosan and potassium sorbate on funga lgrowth on fresh strawberries were not detected.
Other studies have used starch-based coatings incorporated with antimicrobials such as potassium sorbate and citric acid.
However, is important to note that the effec tof coatings based on polysaccharides,such as pectin,pullulan, and chitosan with sodium benzoate and potassium sorbate, have not been studied in strawberries.
