HIGHLIGHTS

● Green production of sugar by membrane filtration is proven to outperform the traditional process.

● Although widely studied at lab/pilotscale, industrialization of membranebased sugar production is still challenging.

● Serious membrane fouling and incomplete cleaning protocols are the most urgent problems to be addressed.

● Development of advanced membrane materials and process intensification technique may solve the problems.

● Integrated membrane process is likely more promising as it enables foulants distribution in different membrane stages.

Abstract

Application of membrane filtration in sugar production is attractive because it can reduce the usage of chemicals, produce high-quality clarified juice, and obtain various high value-added products. However, some technical problems, such as insufficient membrane performance, high sucrose loss in membrane retentate, severe membrane fouling, and incomplete cleaning protocols, limit its industrial applications. In order to facilitate the development of membrane technology for sugar production, this review summarizes recent progress on the applications of membrane filtration in different stages of sugar production as well as the integrated membrane processes for various purposes. Moreover, some important issues including membrane fouling, membrane cleaning, economic feasibility and engineering problems of the membrane-based sugar production process are discussed. Finally, the existing challenges and future research prospects for the industrialization of this green technique are pointed out.
