Approaching the end of the second decade of the 21 century, almost the whole demand of vanillin is met by the synthetic product obtained either via a petrochemical process starting from phenol and glyoxylic acid or from energy intensive alkaline oxidative depolymerization of lignin. Only a minor fraction is comprised of natural vanillin obtained from ferulic acid fermentation, and even less of highly valued extracts. Are there alternative green production methods? And, if yes, are they suitable to find practical application?

临近21世纪的第二个十年尾声，香兰素的几乎全部需求都由合成产品满足，这些合成产品要么通过以苯酚和乙醛酸为起始原料的石化工艺获得，要么通过木质素的高能耗碱性氧化解聚获得。只有一小部分是通过阿魏酸发酵得到的天然香兰素，而高价值提取物所占比例更小。是否存在替代性的绿色生产方法？如果有，它们是否适合实际应用？
