| 中文摘要: |
| 以大豆生物解离纤维素为基料，辅以柠檬酸及丙三醇制备可食性膜，探究环境条件对大豆生物解离纤维素可食性膜性能的影响。结果表明：随着环境温度的升高，可食性膜的拉伸强度、断裂伸长率、溶水时间逐渐增加，但是环境温度对可食性膜的水蒸气透过率和色泽影响较小；随着环境相对湿度的增加，可食性膜的拉伸强度逐渐降低，断裂伸长率、水蒸气透过率、溶水时间增加，色泽无明显变化，亮度略微增加；随着储藏期的延长，拉伸强度、溶水时间增加，断裂伸长率、水蒸气透过率逐渐降低，可食性膜整体变黄。 |
| 英文摘要: |
| With biodegradable soybean cellulose as the base material, supplemented with citric acid and glycerol, edible film was prepared, and the effects of environmental conditions on the performance of biodegradable and edible soybean film was explored. The results showed that the tensile strength, elongation at break and dissolution time of the edible film increased gradually with the increase of ambient temperature, but ambient temperature had little effect on water vapor transmission rate and color of the edible film. The tensile strength decreased, but the elongation at break, dissolution time and water vapor transmission rate increased gradually with the increase of environment relative humidity.There was no obvious change in color, but a slight increase in brightness.The tensile strength and dissolution time increased, while the elongation at break and water vapor transmission rate decreased gradually with the extension of storage period, and the edible film turned yellow. |
