Preparation and preliminary characterization of semi refined kappa carrageenan-based edible film incorporated with cinnamon essential oil AIP Conference Proceedings 1746, 020036 (2016) Abstract. A new patent pending process is proposed in this study to produce edible film directly from seaweed (Kappaphycus alvarezii). Seaweed together with other ingredients had been used to produce the film through casting technique. Physical and mechanical tests were performed on the edible film to examine the thickness, colour, transparency, solubility, tensile strength, elongation at break, water permeability rate, oxygen permeability rate and surface morphology. The produced film was transparent, stretchable, sealable and have basic properties for applications in food, pharmaceutical, cosmetic, toiletries and also agricultural industries. Edible film was successfully developed directly from dry seaweed instead of using alginate and carrageenan. The edible film processing method developed in this research was easier and cheaper compared with the method by using alginate and carrageenan.

komponen asid lemak telah dikenal pasti di mana kandungan asid lemak tepu (SFA) adalah paling tinggi (42.7%-72.8%) diikuti dengan asid lemak mono tidak tepu (MUFA) (13.8%-36.2%) dan kandungan asid lemak poli tidak tepu (PUFA) adalah paling rendah (13.5%-21.2%). Secara kesimpulannya, kajian ini mencadangkan bahawa K. alvarezii dan K. striatum berpotensi digunakan sebagai bahan mentah atau ramuan makanan untuk meningkatkan nilai pemakanan dalam diet manusia.
