| 中文摘要: |
| 本研究以稻草浆纸为基材,通过可逆加成-断裂链转移聚合,将组氨酸功能化咪唑离子液体([Im][His])稳定固定于稻草浆纸的纤维素骨架上,形成聚离子液体(PIL)功能层;随后引入蓝莓花青素(BA)构建协同抗氧化界面,制得PIL/BA改性稻草浆纸(OPC@PB)。结果表明,[Im][His]与稻草浆纸质量比1∶1时制得的OPC@P2B(接枝度27.6%)表现出优异的氧气和水蒸气阻隔性能(氧气透过率降低50%以上,降至4.10 cm³/(m²·d)),以及显著增强的自由基清除能力(由稻草浆纸的不足5%增至90%左右),说明PIL-多酚体系在“电子转移-供氢-金属螯合”机制下能够实现协同抗氧化作用;在25 ℃下将OPC@P2B用于鸡肉保鲜包装时,其能够有效抑制12 h内总挥发性盐基氮及硫代巴比妥酸类物质的积累,并显著减缓鸡肉表面pH值的回升,有效延长鸡肉货架期。 |
| Abstract: |
| In this study, rice straw pulp paper was used as the substrate material. Through radical graft polymerization, histidine-functionalized imidazolium ionic liquid ([Im][His]) was stably immobilized onto the cellulose framework of rice straw pulp paper to form a poly(ionic liquid) (PIL) functional layer. Then the blueberry anthocyanins (BA) were subsequently introduced to construct a synergistic antioxidant interface, resulting in PIL/BA-modified rice straw pulp paper (OPC@PB). The results showed that when the mass ratio of [Im][His] and rice straw pulp paper was 1∶1, the prepared OPC@P2B (grafting degree of 27.6%) exhibited excellent oxygen and water vapor barrier properties (oxygen transmission rate reduced more than 50% to 4.10 cm³/(m²·d)), and significantly enhanced free radical scavenging capacity (increased from less than 5% of rice straw pulp paper to about 90%), indicating that the PIL-polyphenol system can achieve synergistic antioxidant effects via the “electron transfer-hydrogen donation-metal chelation” pathway. When OPC@P2B was used in chicken meat preservation packaging at 25 ℃, it effectively suppressed the accumulation of total volatile basic nitrogen and thiobarbituric acid compounds within 12 h, significantly slowed the rise in surface pH value of the chicken meat, and effectively extended chicken shelf life. |
