Abstract Microwave-assisted cellulose grafting of eugenol was performed in order to incorporate bioactive capabilities to paper for food active packaging. The reaction was optimized using a Doehlert experimental design with three variables: power (200–300 W), time (120–240 s), and eugenol content (2–8 wt%) at constant molar ratio of BTCA:eugenol and SPHI:eugenol (2:1 and 1:1, respectively). The best bioactive paper properties (72.1% DPPH inhibition) were obtained at 230 W, 240 s, and 2 wt% eugenol. However, a high color difference was determined (ΔE* = 12.76) and poor mechanical properties are expected due to the high degradation obtained. A techno-economic study was performed between microwave curing and other as convection and infrared technologies. Despite paper final properties are slightly better in infrared technology; microwave-assisted allows reducing costs compared to convective or infrared technology (12.521 g of reagent/m2 and 0.015 kWh/m2 of paper respectively, i.e. 6.101 USD of total cost per m2 of paper produced).

用于食品包装的微波辅助纤维素接枝。与其他固化技术的技术经济比较

摘要 丁香酚的微波辅助纤维素接枝是为了将生物活性能力结合到用于食品活性包装的纸中。使用具有三个变量的 Doehlert 实验设计优化反应：功率 (200-300 W)、时间 (120-240 秒) 和丁香酚含量 (2-8 wt%)，BTCA:丁香酚和 SPHI 的摩尔比恒定：丁香酚（分别为 2:1 和 1:1）。在 230 W、240 秒和 2 wt% 丁香酚下获得最佳生物活性纸性能（72.1% DPPH 抑制）。然而，确定了高色差（ΔE* = 12.76）并且由于获得的高降解而预期机械性能差。在微波固化和其他对流和红外技术之间进行了技术经济研究。尽管纸张的最终性能在红外技术中稍好一些；
