| description | Recent alternative in the development of bioactive packaging films which contribute both to reduce waste disposal problems and prolong shelf life of food have received attention among consumers. Semi-refined carrageenan (SRC) based film plasticized with glycerol (G) reinforced with different concentration cellulose nanofibre (CNF) (2%, 5%, 7%, and 10% [w/w]) incorporated with 0.4% (w/w) α-tocopherol were prepared for food packaging application. Functional mechanical and physical properties of SRC-based films were characterized. The release of antioxidant α-tocopherol from SRC-based film were studied based on total phenolic content (TPC) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) throughout 31 day storages. FTIR spectra analysis provided some insight interaction between SRC, glycerol, CNF and antioxidant α-tocopherol. The result shows incorporation of CNF increased the mechanical properties of SRC-based film when compared to the control film. The filling effect of CNF caused an increase in elongation and tensile strength. When a high content of CNF (10%) was incorporated in the films, the water solubility was decreased due to the reduction of hydrophilic domains in the film matrix. Moreover, addition of α-tocopherol into films contained phenolic compounds displayed strong antioxidant activities. These results demonstrate that CNF and α-tocopherol can significantly enhance the mechanical properties, antioxidant ability, and reduce the water solubility of SRC-based films that can be used as an active food packaging material. Hence, the incorporation of CNF into SRC-based film could be an alternative way to replace non-biodegradable plastic whilst reduce the use of synthetic antioxidant directly into food product. |
