Chitosan is a natural bioactive polysaccharide with intrinsic antimicrobial activity and has been recognized as a natural alternative to chemically synthesized antimicrobial polymers. This, associated with the increasing preference for biofunctional materials from renewable resources, resulted in a significant interest on the potential for application of chitosan in packaging materials. Oils extracted from plants have been the focus of numerous researches due to their potential in the food and pharmaceutical industries. An antimicrobial food packaging material was developed from chitosan with different concentrations (0.6%; 0.9%; and 1.2%) (v/v) of red ginger (Zingiber officinale var. rubrum) extract. Analysis by GCMS revealed that zingiberene (10.3%), ar-Curcumene (15.6%), α-Pinene (3.12%), β-Pinene (0.5%), trans geraniol (0.69%), 1.8 Cineole (7.52%), Endo borneol (0.46%) and β-Sesquiphellandrene (8.74%) as major components of the oil. The effect of extract’s concentration to the physic-chemical properties, and microbiological and sensory quality of milkfish during 6 days of storage (4±1oC) were evaluated. Protected milkfish with film and unprotected milkfish were stored under the same conditions. The effect of glycerol as plasticizer to the tensile strength of films were observed. The films were also characterized by using of SEM analysis for surface morphological properties. The results obtained indicated that films produced from chitosan plasticized with glycerol and incorporated with red ginger extract exhibited good tensile strength and swelling behavior, also high antioxidant and antimicrobial activity. Analysis of yeast and mould counts; and total plate counts of protected milkfish samples containing red ginger were lower than unprotected samples. Therefore, the results indicate that chitosan-based films formulation incorporated with red ginger have potential as an active packaging for food safety and to extend the shelf-life of milkfish.
