Due to lactose intolerance, there is a growing need for lactose-free or low-lactose dairy products. Herein, a combination of three membrane technologies (UF, electrodialysis (ED), and nanofiltration (NF)) was used as a novel green technology to replace the enzymatic preparation of low-lactose milk powder in the traditional industry. In which, large molecules such as proteins and fats are first retained using UF, mineral salt was intercepted and re-added into milk by electrodialysis, and finally, lactose is recovered by NF. Finally, low-lactose milk powder with a lactose content of less than 0.2% was obtained; meanwhile, the high purity (95.7%) of lactose powder could be effectively reclaimed from the NF concentrate (lactose concentrate). The whole membrane process is based on the physical pore size screening mechanism, without adding any chemical reagents with minimal impact on the physical and chemical properties of milk. These results indicate that process development and optimization coupling of three membrane technologies is very promising in preparing low-lactose milk powder and recovering lactose.

“…The major advantages of dynamic filtration are more profound in low MWCO membrane as they will enable operation at high TMP and rise flux until 4000 kPa owing to the extended pressure-controlled regime and lower concentration polarization. Both promising concentration factor (CF) (defined as the ratio between concentration of the concentrate recovered after filtration to initial concentration of solution filtered) and membrane selectivity can be gained with highly viscous solution, and these are implicated in high water recovery [141,142]. Moreover, using the second generation of shear-enhancing modules like vibratory shear-enhanced processing (VSEP) or multishaft rotating membranes (RDM) and choosing ceramic (not polymeric) membranes, the performance of dynamic UF can be powerfully enhanced [33,143].…”

Recent Advancements of UF-Based Separation for Selective Enrichment of Proteins and Bioactive Peptides—A Review

Proteins are one of the primary building blocks that have significant functional properties to be applied in food and pharmaceutical industries. Proteins could be beneficial in their concentrated products or isolates, of which membrane-based filtration methods such as ultrafiltration (UF) encompass application in broad spectra of protein sources. More importantly, selective enrichment by UF is of immense interest due to the presence of antinutrients that may dominate their perspicuous bioactivities. UF process is primarily obstructed by concentration polarization and fouling; in turn, a trade-off between productivity and selectivity emerges, especially when pure isolates are an ultimate goal. Several factors such as operating conditions and membrane equipment could leverage those pervasive contributions; therefore, UF protocols should be optimized for each unique protein mixture and mode of configuration. For instance, employing charged UF membranes or combining UF membranes with electrodialysis enables efficient separation of proteins with a similar molecular weight, which is hard to achieve by the conventional UF membrane. Meanwhile, some proposed strategies, such as utilizing ultrasonic waves, tuning operating conditions, and modifying membrane surfaces, can effectively mitigate fouling issues. A plethora of advancements in UF, from their membrane material modification to the arrangement of new configurations, contribute to the quest to actualize promising potentials of protein separation by UF, and they are reviewed in this paper.

“…Ultrafiltration (UF) is an emerging low pressure membrane technique that separates macromolecular proteins, organic contaminants, microorganisms and tiny particles present in the feed streams with relatively simple operation . In contrast, membrane fouling that arises from continuous accumulation of solutes on the membrane surface (active layer) limits its widespread application .…”

BACKGROUND: Ultrafiltration (UF) is a promising separation technique for the removal of macromolecular contaminants. However, the hydrophobic polymeric UF membrane performance suffers from fouling in the long run due to clogging by contaminants at the surface and pores. In this study, anti-fouling hydrophilic polyacrylonitrile (PAN) UF membranes in the presence of an amphiphilic triblockcopolymer, Pluronic F127 (PF127) were prepared via a phase inversion technique. RESULTS: The effect of varying concentrations of PF127 on PAN UF membranes was analyzed by attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The filtration characteristics of the membranes were measured in terms of pure water flux, membrane porosity and water content. The separation efficiency of the membranes is explored for contaminants such as bovine serum albumin (BSA), humic acid (HA) and oil. The results revealed that the PAN membrane with 4 wt% of PF127 produced greatest permeate flux of 391 L m −2 h −1 with minimal fouling. A higher solute rejection of more than 90% was observed for the tailored membranes due to the improvement in surface properties. CONCLUSION:The inherent hydrophilicity of the high density poly (ethylene oxide) brush-like layer of PF127 at the membrane-water interface is utilized effectively to restrict the adsorption of the organic contaminants onto the membrane surface. After simple hydraulic washing of PAN/PF127 UF membranes, the flux recovery ratio was augmented which is ascribed to their excellent antifouling property and potential use in water treatment.
