Abstract

The food packaging industry is one of the fastest growing sectors of our economy, with a large contribution to environmental concerns due to the extensive use of fossil-derived materials. Combining wood-based materials, such as particleboards, with bio-adhesives may offer a great opportunity to develop sustainable packaging solutions with active antioxidant properties. In the present work, a phenolic extract of poplar bark was produced and bio-adhesives were formulated using citric acid as a cross-linker. The impact of citric acid content on the chemical and bonding properties of bio-adhesives was evaluated. Additionally, the impact of the temperature of curing on their antioxidant capacity was also accessed. The bio-adhesives were applied in the production of particleboards, using poplar veneer particles as raw material. The composite materials exhibit high mechanical resistance, fulfilling the requirement of PB type P1, with remarkable antioxidant activity, opening a possibility to be employed in an active packaging solution.

利用森林副产品生产抗氧化刨花板及其在食品包装工业中的应用。

食品包装行业是我国经济增长最快的部门之一，由于广泛使用化石衍生材料，对环境问题做出了很大贡献。将刨花板等木质材料与生物粘合剂相结合，可能为开发具有活性抗氧化性能的可持续包装解决方案提供了一个很好的机会。在本工作中，制备了杨树树皮的酚类提取物，并以柠檬酸为交联剂配制了生物胶粘剂。考察了柠檬酸含量对生物胶粘剂化学性能和粘合性能的影响。此外，还探讨了固化温度对其抗氧化能力的影响。以杨木贴面颗粒为原料，将生物胶粘剂应用于刨花板的生产。该复合材料具有较高的机械阻力，满足PB型P1的要求，并具有显著的抗氧化活性，为活性包装溶液的应用开辟了可能性。

期刊介绍： Polymers (ISSN 2073-4360) is an international, open access journal of polymer science. It publishes research papers, short communications and review papers. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Polymers provides an interdisciplinary forum for publishing papers which advance the fields of (i) polymerization methods, (ii) theory, simulation, and modeling, (iii) understanding of new physical phenomena, (iv) advances in characterization techniques, and (v) harnessing of self-assembly and biological strategies for producing complex multifunctional structures.
