ABSTRACT
This research is focused on improving performance of chitosan based functional material by introducing active additive. A series of assays revealed incorporation with clove essential oil (CEO) significantly improved the physical, chemical and antimicrobial performance of chitosan. In this work, the prepared chitosan-CEO film (CH-CEO) showed varieties in color parameters, mechanical strength and water vapor permeability. Moreover, chitosan was endowed with significant antioxidant and antimicrobial activities, thereby it was used as protective coatings for fresh-cutting apple tubes at ~1 °C. Results demonstrated the treatment slowed down the quality deterioration process of preserved apple samples, especially for firmness and color. As well, CH-CEO coating reduced microbial counts in the preserved apple samples and inhibited the varieties in the chemical properties. The overall observations revealed that CH-CEO film has remarkable potential as an antioxidant and antimicrobial material, especially as an active coating for fresh-cutting foods during storage.
