ABSTRACT

By-products obtained through the industrial processing of rapeseed and mustard seeds are exploited as feed or methanization. However they contain high added value phenolic compounds, such as sinapic acid and its derivatives, that could be recovered by extraction and purification processes. This review presents the state of the art on such recovery processes. It covers conventional extraction by solvent and emergent extraction processes, namely solvent extraction assisted by ultrasound, microwaves, pressure, electro-technologies or enzymes. Concerning the purification processes, liquid-liquid extraction, adsorption and membrane filtration processes are commonly implemented. This article summarizes the most promising methods and technologies for developing sustainable processes for the recovery of sinapic acid derivatives from rapeseed and mustard seed by-products.

摘要

通过油菜籽和芥菜籽的工业加工获得的副产品被用作饲料或甲烷化。然而，它们含有高附加值的酚类化合物，例如芥子酸及其衍生物，可以通过提取和纯化过程进行回收。本综述介绍了此类恢复过程的最新技术。它涵盖了传统的溶剂提取和紧急提取工艺，即通过超声波、微波、压力、电技术或酶辅助的溶剂提取。关于纯化过程，通常实施液-液萃取、吸附和膜过滤过程。
