Abstract Whey is considered as a by-product of dairy industries and commonly regarded as waste. Despite being a good source of nutrients (lactose, minerals, and bioactive peptides), it is commonly discarded as effluent. Innovative techniques such as membrane filtration, chromatography (affinity and ion exchange), chemical treatments, and/or combination of these are used for the extraction of these constituents. The presence of these components in whey makes it functional in food and pharmaceutical industries. This article is aimed at supplementing recent information to available literature about different novel techniques used for the separation of whey constituents and their industrial application. In future, information reviewed will be helpful for the processors to select the best technique for the separation of individual constituents for the attainment of maximum yield and purity.

乳清增值纯化技术和工业应用的最新进展：综述

摘要 乳清被认为是乳制品工业的副产品，通常被视为废物。尽管它是营养物质（乳糖、矿物质和生物活性肽）的良好来源，但通常作为废水丢弃。诸如膜过滤、色谱法（亲和和离子交换）、化学处理和/或这些方法的组合等创新技术用于提取这些成分。乳清中这些成分的存在使其在食品和制药行业中发挥作用。本文旨在补充有关用于分离乳清成分及其工业应用的不同新技术的现有文献的最新信息。在未来，
