【 摘 要 】

Edible film based on beeswax and carrageenan has been made using two types of plasticizers namely glycerol and sugar. Glycerol at a fixed concentration of 1% was combined with sugar (fructose, glucose and sucrose) each at three concentration levels of 0.5%, 1% and 1.5% w /vt. Edible film has water content, thickness, tensile strength, elongation and vapor transmission rate respectively 13.69-14.91%, 0.059-0.102 mm, 12.62-32.40 MPa, 13.34-43.57% and 17.65-25.38 g/m2/24 hours. The enhancement in plasticizer concentration resulted increasement of moisture content, thickness, elongation and water vapor transmission rate but decreased its tensile strength. All edible films showed lightness in range 84.45-85.61. Edible films with glycerol-sucrose plasticizer showed the lowest lightness. The scanning electron microscopy results indicated that edible films treated with plasticizer glycerol-fructose and glycerol-glucose have more homogeneous and smoother surface than edible control films and edible films with a glycero l -sucrose plasticizer.
