以壳聚糖 / 淀粉复配防油剂制备了食品抗油包装材料,研究了制备条件对其性能的影响。 结果表明:纸张的抗油脂值随防油剂质量分数、防油剂用量的增加而增大;用阳离子淀粉取代部分壳聚糖制备的复合防油剂,完全可以达到单一壳聚糖防油剂的效果,从而可以降低生产成本。

The oil repellent paper was prepared by using chitosan and cationic starch to produce oil and grease resistant material for food packaging. The influence of preparation condition on performance of the material was studied. The results showed that the oil and grease resistance of paper increases with mass fraction of oil repellent agent; the composite oil repellent agent prepared by substituting partial chitosan with cationic starch can achieve the same effect as pure chitosan and reduce production cost
