The depectinised juice was processed according to a batch concentration confguration in selected operating conditions (transmembrane pressure, 1.6 bar; feed flowrate 70 L/h; temperature, 25±2 °C) up to a volume reduction factor (VRF) of 1.8. The quality of clarifed juice was analysed in terms of total antioxidant activity (TAA), content of ascorbic, malic, succinic and citric acid, total polyphenols, suspended solids and total soluble solids (TSS). The prepared membranes allowed to remove suspended solids producing a clear juice with a content of organic acids, vitamin C and polyphenols comparable to that of the fresh juice. Accordingly, the TAA of the fresh juice was well preserved in the clarifed juice.}, keywords = {Kiwifruit juice,Hollow fber membranes,Poly (ether ether ketone) (PEEK-WC),Fruit juice clarifcation}, url = {https://www.msrjournal.com/article_26316.html}, eprint = {https://www.msrjournal.com/article_26316_adebc5653310d6ae99d3e87566d1aa7f.pdf} }
