“…The current efficiencies obtained for all hCEMs used for whey demineralization are lower than those obtained by Francesco et al [ 13 , 14 ] for NaCl desalination (44.28% vs. 93.42%) due to the complexity of the whey solution. In addition, these observations are as expected since the current efficiency for laboratory cell setups can reach up to 90%, whereas it can only reach up to 50% for industrial installments [ 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 ]. The setup for this present study is closer to an industrial commercial installment.…”

Hierarchical cation-exchange membranes (hCEMs) fabricated by blade coating and UV crosslinking of ionomer on top of a porous substrate demonstrated promising results in performing NaCl demineralization. In the food industry, complex solutions are used and hCEMs were never investigated before for these food applications. The performances of two different coating chemistries (urethane acrylate based: UL, and acrylic acid based: EbS) and three crosslinking degrees (UL5, UL6, UL7 for UL formulations, and EbS-1, EbS-2, EbS-3 for EbS formulations) were formulated. The impacts of hCEMs properties and crosslinking density on whey demineralization performances by electrodialysis (ED) were evaluated and compared to CMX, a high performing CEM for whey demineralization by ED. The crosslinking density had an impact on the hCEMs area specific resistance, and on the ionic conductance for EbS membrane. However, 70% demineralization of 18% whey solution was reached for the first time for hCEMs without any fouling observed, and with comparable performances to the CMX benchmark. Although some properties were impacted by the crosslinking density, the global performances in ED (limiting current, demineralization duration, global system resistance, energy consumption, current efficiency) for EbS and UL6 membranes were similar to the CMX benchmark. These promising results suggest the possible application of these hCEMs (UL6, EbS-2, and EbS-3) for whey demineralization by ED and more generally complex products as an alternative in the food industry.

Electromembrane processes are well‐established techniques for the production of potable water from brackish water. During recent years, these processes have witnessed penetration into many areas such as energy production, food processing, personal care products, healthcare, production of high quality water, biomolecules separation, sensors, organic separation, industrial effluent treatment, etc. In this article, the principle of the electromembrane process is described along with its advantages and limitations for various applications. Recent developments in ion‐exchange membranes and their utilization in various areas are also described briefly.

Biological activities of chitosan oligosaccharides (COS) are well documented, and numerous reports of COS production using specific and non-specific enzymes are available. However, strategies for improving the overall yield by making it monomer free need to be developed. Continuous enzymatic production from chitosan derived from marine wastes is desirable and is cost-effective. Isolation of potential microbes showing chitosanase activity from various ecological niches, gene cloning, enzyme immobilization, and fractionation/purification of COS are some areas, where lot of work is in progress. This review covers recent measures to improve monomer-free COS production using chitosanase/non-specific enzymes and purification/fractionation of these molecules using ultrafiltration and column chromatographic techniques. Various bioprocess strategies, gene cloning for enhanced chitosanase enzyme production, and other measures for COS yield improvements have also been covered in this review. COS derivative preparation as well as COS-coated nanoparticles for efficient drug delivery are being focused in recent studies.
