| 中文摘要: |
| 目的 研究基于PLA/PBAT可生物降解食品保鲜袋中成分的测定，以及其中增塑剂乙酰柠檬酸三丁酯(ATBC)的迁移规律。方法 采用气相色谱-质谱联用仪检测材料中的成分及向食品模拟物中的迁移情况，并以此为基础，研究不同温度、不同厚度、不同时间、不同模拟物对ATBC迁移规律的影响;并采用红外光谱和扫描电镜从微观分析薄膜浸泡前后的变化。结果 在温度和厚度相同的条件下，ATBC在体积分数为95%的乙醇中迁移量最大;在同一种食品模拟物中，温度越高、时间越长，ATBC的迁移量越大;在温度和食品模拟物保持相同的条件下，厚度越小，ATBC的迁移量越大。结论 食品模拟物的性质、温度、厚度和时间都是影响ATBC迁移行为的重要因素。 |
| 英文摘要: |
| The study is based on the determination of PLA/PBAT-based biodegradable food preservation bags and the migration of the plasticizer acetyl tributyl citrate (ATBC). A gas chromatography-mass spectrometer was used to detect the components in the material and the migration to the food simulant. Based on this, the influence of different temperatures, different thicknesses, different times, and different simulants on the migration regular of ATBC were studied. And FTIR and SEM were used to analyze the changes of the film before and after soaking. Under the conditions of the same temperature and thickness, the migration amount is the largest in ethanol with a volume fraction of 95%; under the same food simulant, the higher the temperature and the longer the time, the greater the migration amount of ATBC; under the same temperature and food simulants, the smaller the thickness, the greater the migration of ATBC. The nature of food simulants, temperature, thickness and time are important factors affecting the migration behavior of ATBC. |
