Produced by extraction from certain woods and barks with boiling water, tannin is the name given to a mixture of high molecular weight biophenols increasingly used in a number of industries. This study offers a new bioeconomy insight into an old natural product that, we argue in this study, will likely play a crucial role in the development of the bioeconomy of forest regions. After providing an updated picture of selected key economic and production aspects, we show how flourishing research on tannin's biological activity and technological applications has revealed many new properties that are likely to drive significant growth in demand in the near and mid-term future. The study concludes with two lessons learned and one forecast that will hopefully accelerate progress in the bioeconomy of forest areas based on the circular economy of tannin enabled by new extraction and purification technologies. © 2021 Society of Industrial Chemistry and John Wiley & Sons Ltd.

单宁：对林区生物经济关键产品的新见解

通过用沸水从某些木材和树皮中提取生产，单宁是一种高分子量生物酚混合物的名称，越来越多地用于许多行业。这项研究为一种古老的天然产品提供了新的生物经济见解，我们在本研究中认为，它可能在森林地区生物经济的发展中发挥关键作用。在提供选定的关键经济和生产方面的最新图片后，我们展示了对单宁的生物活性和技术应用的蓬勃发展的研究如何揭示了许多可能在近期和中期推动需求显着增长的新特性。该研究总结了两项经验教训和一项预测，有望加速基于新提取和纯化技术实现的单宁循环经济的林区生物经济进展。© 2021 工业化学学会和约翰威利父子公司。
