Typically, the various agro-food by-products of the food industry are treated by standard membrane processes, such as microfiltration, ultrafiltration and nanofiltration, in order to prepare them for final disposal. Recently, however, new membrane technologies have been developed. The recovery, separation and fractionation of high-added-value compounds, such as phenolic compounds from food processing waste, are major current research challenges. The goal of this paper is to provide a critical review of the main agro-food by-products treated by membrane technologies for the recovery of nutraceuticals. State-of-the-art of developments in the field are described. Particular attention is paid to experimental results reported for the recovery of polyphenols and their derivatives of different molecular weight. The literature data are analyzed and discussed in relation to separation processes, molecule properties, membrane characteristics and other interesting phenomena that occur during their recovery.
通常，食品工业的各种农业食品副产品通过标准膜工艺进行处理，如微滤、超滤和纳滤，以便为最终处置做好准备。然而，最近已经开发出了新的膜技术。从食品加工废料中回收高附加值化合物，如酚类化合物，进行分离和分级，是当前主要的研究挑战。本文的目的是对通过膜技术处理以回收营养保健品的主要农业食品副产品进行批判性综述。描述了该领域的最新发展情况。特别关注了有关回收不同分子量多酚及其衍生物的实验结果。针对分离过程、分子特性、膜特性以及回收过程中出现的其他有趣现象，对文献数据进行了分析和讨论。
