| Abstract: | Sodium alginate, chitosan, glycerin and sodium dodecyl sulfate were used to prepare edible alginate film. The best processing parameters were confirmed by orthogonal test. The influence of removal agents and its dosage, drying temperature and time on film properties were also studied. The results showed the best ratio of film solution composing was :sodium alginate 30mg/mL, chitosan 2 mg/mL, glycerin 10μL/mL, sodium dodecyl sulfate 0.5mg/mL. The best condition for removal agent was Tween 80 at 0.5μL/cm2.The best drying temperature and time were 50℃ for 4.5h. |
