Dissertation note: Final Year Report (Bachelor of Chemical Engineering ) -- Universiti Malaysia Pahang Al-Sultan Abdullah - 2025 Abstract: This research investigates incorporating green tea extract Pickering emulsions into semi-refined carrageenan-gelatin hybrid films for food packaging. Active packaging with natural antioxidants is promising for extending the shelf life of perishable food. However, biopolymers like semi-refined carrageenan (SRC) alone do not form films with adequate mechanical properties, limiting their potential for food protection. Reinforcing fillers can enhance film properties for active packaging. This study aims to produce active packaging films from SRC plasticized with glycerol (G), enhanced with gelatin (Ge), and incorporated with different concentrations of green tea extract Pickering emulsion. The films will be analyzed for mechanical properties (tensile strength (TS) and elongation at break (EAB)), physical properties (water solubility, moisture content (MC), opacity, and thickness), antioxidant release (DPPH assay), and Fourier-transform infrared spectroscopy (FTIR). The films will be produced by casting technique with Pickering emulsion concentrations of green tea extract (1, 3, 5, 7 and 10 ml of 0.05 g/ml) in a matrix of gelatin (4% w/v), SRC (2% w/v), and glycerol (40% v/v based on SRC weight). Encapsulating green tea extract in Pickering emulsions offers benefits like enhanced loading efficiency, reduced coalescence, and controlled release, prolonging antioxidant activity and maintaining food freshness. The results will demonstrate the effect of green tea extract addition on film characterization, showing the potential of SRC-based films with natural extracts for active food packaging. This approach aims to create sustainable packaging solutions that address environmental concerns and food safety requirements. The outcomes will contribute to developing advanced packaging materials that ensure food safety while being environmentally friendly.
